Introduction

A beech forest after the rain sounds of soaked leaves and water running down between the branches. Spain holds corners like this, and many others that almost nobody expects to find.

These 15 facts about Spanish nature bring together little-known surprises of the countryside. Each one gives you context and a practical tip so you can go out and see it for yourself, near home or on a weekend getaway.

Context to understand the territory

Spain fits into a medium-small part of Europe and, even so, brings together alpine, Mediterranean, Atlantic and subtropical climates. That mix explains why the landscape changes so much in just a few kilometres.

More than 27% of the land territory is part of the Natura 2000 network, with 1,479 SCIs and 659 SPAs and more than 336,000 km2 of total surface area. Add to that 16 National Parks and first place in the world for UNESCO Biosphere Reserves.

When you plan an outing, check the climate of the area and the protection figure that covers it: it will tell you what to expect and which rules to follow.

What you'll take away from this read

Fifteen facts about Spain's nature, each one with a specific place where you can check it. The article brings together key landscapes, biodiversity, parks and possible activities, and adds a section of frequently asked questions.

It smells of thyme when you open the car door on a country track. That is the gateway to a route that also tells you the best time for each phenomenon or landscape and how to move around safely and respectfully.

By the end, you'll know where to go, when to go and how to look after what you visit.

Where, when and how to see the essentials

Planning well multiplies the quality of the experience and reduces impacts. Spain is easy to travel by train and plane between capitals, and by car or bus you reach the last valley.

The Atlantic north (Galicia, Asturias, Cantabria, the Basque Country and the Cantabrian Mountains) has deciduous forests, cliffs and brown bears, with a humid, mild climate. The Mediterranean (Catalonia, the Valencian Community, Murcia and eastern Andalusia) adds coves, marshes and coastal steppes, with dry summers and mild winters. In the interior (the Meseta, the Central System and the Iberian System) you find dehesas, juniper groves, high plateaus and gorges, with marked temperature extremes. The Canary Islands bring volcanoes, laurel forest and a coastline of cetaceans, with a subtropical climate and trade winds, and the Balearic Islands, Posidonia meadows, coves and wetlands such as s'Albufera.

The mountains are visited from late June to September; for alpine blooms, from mid-June to July. In wetlands and marshes there are migratory peaks in March-May and September-November, and wintering of Anatidae in December-February. Dunes and coastlines call for spring and autumn to avoid heatwaves and overcrowding, and checking the tides to cross tombolos and sandbars safely. Dehesas and Mediterranean forests are at their best in autumn (mushrooms, the rut) and spring (blooms).

To get around, AVE/AVLO/SNCF reaches Madrid, Barcelona, Valencia, Seville and Málaga, and regional trains bring you close to provincial capitals next to natural parks. Planes connect the islands and main cities, and ferries go to the Canary and Balearic Islands from Huelva/Cádiz and Dénia/Valencia/Barcelona. A shared or rental car gives you flexibility for valleys and tracks: respect closed tracks and signage.

Sleep in rural accommodation (country houses, inns, cortijos) near trails and observation points, or in campsites and authorised motorhome areas, never wild camping outside the regulations. Some parks have mountain refuges (e.g. the GR-11 in the Pyrenees) and visitor centres with up-to-date information. Check the regulations on the MITECO and each region's websites: some accesses limit visitor numbers (Doñana, Teide, Sierra de las Nieves). Don't leave the waymarked trails, don't remove sand or flora and keep quiet during breeding seasons.

Practical tip

Travel light but with 8x32 binoculars, a headtorch, an offline map and extra water; prepare a plan B if the weather changes.

15 facts that will surprise you

1. Climatic diversity: from ice to trade wind in hours

Spain brings together alpine, Mediterranean, Atlantic and subtropical climates, and that mix is one of the greatest climatic variations in Europe over short distances.

That gradient creates very different biomes: alpine grasslands, damp beech woods, Mediterranean scrub, cold deserts and laurel forests. The thermal and rainfall swing between slopes and latitudes sustains much of the country's biodiversity.

The contrast shows on routes such as the GR-11 (Pyrenees), the GR-7 (Andalusia–Valencia) or going from the Caldera de Taburiente to the Garajonay forest in the Canaries. The GR-11, also called the Senda Pirenaica, crosses the Spanish Pyrenees from west to east with sections in Andorra: it exceeds 800 km, is mainly a mountain route and is signposted almost entirely with white and red marks. It runs from Cape Higuer, on the Cantabrian Sea, to Cape Creus, on the Mediterranean. The GR-7 is 2699 km long and is waymarked with red and white signs. The Caldera de Taburiente stands out for its great quantity of water resources, both surface and underground.

This fact helps you choose the season: a Cantabrian beech wood is not planned the same way as a volcano under the trade winds. Compare forecasts by district and design the itinerary with a plan by altitude.

2. Microclimates and rocks: valleys that keep their own time

A beech wood can survive in a shady cirque surrounded by dry holm oak groves. It happens when topography and rocks change the local weather: enclosed valleys, north-facing shady slopes, sunny slopes and materials that retain or drain heat and moisture.

The shady slopes of Montseny preserve damp relicts. The park has been a Unesco biosphere reserve since 1978 and keeps relict species such as the sundews, the Sant Segimon herb or the gentian. There are European beeches and firs above 1000 m, and on the summits scrub and meadows of subalpine character appear.

The Picos de Europa include the largest limestone formation in Atlantic Europe. In Tenerife, the Barranco de Masca shows the contrast between shady and sunny sides within a few metres. The Desfiladero de los Gaitanes (Málaga) is 10 metres wide at its narrowest stretches and reaches more than 400 metres in height.

The rock sweated after a short fog smells of stone and moss.

Spring and autumn maximise the thermal contrasts and the flowerings; in summer, you should visit early. These refuges keep sensitive species: walk along signposted trails and avoid shouting in narrow gorges where birds of prey nest.

3. Glaciers and peaks: the last ice of the Pyrenees

Less than 200 hectares of active ice remain in the Pyrenees, according to the Pyrenean Institute of Ecology (CSIC). The Spanish glaciers survive in high cirques and have been retreating rapidly since the 19th century.

In the 1980s there were 50 glaciers; today there are 14. The average thickness has dropped by 7 metres in Monte Perdido, Maladeta and Aneto, and between 2016 and 2020 more than 10% of the ice mass was lost.

Three massifs concentrate the views. The Maladeta/Aneto Massif is in Huesca. Monte Perdido, in Ordesa, is the highest limestone massif in Europe, with Punta de Treserols (3348 m) as its highest peak. The Vignemale, on the border, reaches 3299 m and its Spanish face lies in the Bujaruelo Valley.

Before you go up, check the AEMET snow and weather bulletin. Don't step on live ice without a guide because of the risk of crevasses and snow bridges, and follow the GR-11 or HRP tracks with official IGN maps.

These glaciers are indicators of climate change. Scientific monitoring campaigns depend on responsible access with no shortcuts that cause erosion.

4. Moving dunes: beaches in constant transformation

Coastal dunes are living mountains of sand: they advance with the wind and European beachgrass and other pioneer plants gradually fix them in place. In Spain they act as natural shields against storms.

In Cádiz, the Bolonia dune is a climbing dune of about 30 m next to Baelo Claudia. Corralejo (Fuerteventura) has the largest dune fields in the Canary Islands, protected, with a mobile dune field over Upper Pleistocene fossil dunes and outcrops of a fossil beach with remains of marine organisms.

In the Ebro Delta (Tarragona) you'll find bars such as the Trabucador, 6 km long, which reaches the Salinas de la Trinidad. Spring, especially from April to May, coincides there with the breeding of the greater flamingo; in winter large flocks gather in the lagoons as temperatures drop.

Step only on the sand: your footprints on the fixing vegetation speed up erosion. Don't remove sand or shells either, because it is punishable and harmful. Watch out for temporary access points closed for nesting and visit at sunrise or sunset, when there are gentle breezes and fewer people. These dunes change their profile every season.

5. Marshes and wetlands: airports for birds

Every year, millions of birds migrating between Europe and Africa stop at Spanish wetlands to refuel. Doñana and the Ebro Delta concentrate waders, herons and waterfowl in numbers counted in the thousands.

Doñana (Huelva, Seville and Cádiz) is Europe's largest ecological reserve and a UNESCO World Heritage Site since 1994. Endangered species such as the Iberian lynx and the Spanish imperial eagle live there, and more than 400 bird species are observed throughout the year. The peaks come in March-May and September-November, and between December and February geese and ducks overwinter.

In August the extreme heat bears down and wildlife hides during the central hours of the day. Book your excursions well in advance so you don't miss out on a place.

The Ebro Delta (Tarragona) combines rice fields and lagoons, with flamingos all year round and marked migrations in spring and autumn. Las Tablas de Daimiel (Ciudad Real) are a fluctuating oasis that depends on the inputs from the Guadiana and on rainfall, between the municipalities of Daimiel and Villarrubia de los Ojos.

Observe from hides and boardwalks, with 8x32 binoculars or a 20–60x telescope. Avoid drones and noise, and respect track closures.

Wetlands filter water, buffer floods and store carbon. SEO/BirdLife and Ramsar recognise their global value, and you can contribute to citizen science with eBird or Observado without revealing sensitive locations.

6. Singular forests: beech woods, cork oak groves and laurel forest

Spain has forests from three worlds at once: Atlantic deciduous, Mediterranean evergreen and subtropical relicts. In one and the same country there is room for beech woods that grow in cold mists, cork oak groves with rich undergrowth and humid forests of ancient origin.

The Irati beech wood is in Navarra. The cork oak groves of the southwest are concentrated in Los Alcornocales, between Cádiz and Málaga, with humid canutos and rich undergrowth.

Anaga is the place with the greatest number of endemics in Europe and the most important natural area in Tenerife after the Teide National Park.

There the laurel forest is a relic of the Tertiary Era, with flora that occupied Europe millions of years ago. Its vertebrate fauna is limited to birds and bats, with the endemic laurel pigeon and bolle's pigeon as the most representative birds.

These forests support key fauna (woodpeckers, mustelids, endemic invertebrates) and local economies such as cork, guided tours and mycology. It is best to visit them outside the peaks of overcrowding and to walk on boardwalks where they exist so as not to compact the soils.

7. Endemics you'll only see here: from the lynx to unique lizards

More than 1,000 Iberian lynx were estimated in Spain in 2023, Europe's most threatened feline and today recovering. Seeing one requires choosing the right place and the right company.

The Iberian lynx (Lynx pardinus) is sought in Sierra Morena, Montes de Toledo and Doñana. Routes with accredited guides improve your chances of a sighting.

The Iberian ibex is endemic to the Iberian Peninsula and lives in mountain ranges between 500 and 3,400 metres of altitude, such as Gredos and Cazorla. The males sport lyre-shaped horns up to 75 cm long, with rings that indicate their age.

In the Canary Islands, island isolation explains cases such as the Tenerife blue chaffinch (Fringilla teydea/polatzeki) and the Gallot's lizards (Gallotia spp.). The dragontree (Dracaena draco) is native to Macaronesia and north-west Africa.

Tenerife blue chaffinches are seen in the high mountains of Tenerife and in the pine forests of Gran Canaria. A hum of cicadas underlines the silence when a feline silhouette appears.

Their uniqueness demands distance, silence and not feeding the animals. Responsible tourism funds conservation and rural employment.

8. Migration corridors: a bridge between two continents

Every autumn, thousands of white storks, kites and eagles cross the Strait of Gibraltar heading for Africa. Spain acts as a natural funnel for birds between Europe and Africa, and the Strait of Gibraltar is a great migratory gateway.

Soaring birds make use of thermals to gain altitude without spending energy. The column of birds circling in a thermal looks like a living whirlwind.

To see them, there are key wetlands: Doñana, the Ebro Delta, Gallocanta and Villafáfila, with great bustards and Anatidae. Gallocanta is Europe's largest endorheic saltwater lagoon and the best-preserved saline wetland in the West, with its common cranes; in Villafáfila you'll see great bustards and Anatidae.

This geographical position explains part of Spain's biodiversity and justifies the protection of strategic points. The post-nuptial passage runs from July to October, so that's your window.

Observe from the official viewpoints of Cazalla and Algarrobo, in Tarifa, without invading the roosts. If you're a beginner, count on accredited local guides.

9. National parks with a personality of their own

Spain has national parks with landscapes that don't resemble each other: the largest limestone formation in Atlantic Europe in Picos de Europa, Monte Perdido in Ordesa y Monte Perdido, a volcanic cone of 3,715 m in the Teide, the volcanoes of Timanfaya and the marshes of Doñana.

Each one has its best moment. In the Teide, look for clear skies in winter and the flowering of the viper's bugloss in May-June. In Doñana, migrations arrive in spring and autumn, and breeding is concentrated in spring. Picos de Europa and Ordesa call for hiking in summer and colourful autumns.

Ordesa y Monte Perdido receives an average of more than 600,000 visitors a year, so it's worth choosing the date well. In Timanfaya, the 2 km route is of minimal difficulty and lasts about 3 h; the 3.5 km route is done in 2 hours. The meeting point for the Litoral route is the north car park of the village of El Golfo.

The parks are laboratories of conservation and responsible visiting. Stop by the visitor centres to get updated routes and rules before setting out.

10. Living volcanoes: the Canaries as an open-air classroom

In the Canaries the steep relief, the young soils and the endemic species all stem from volcanism. Historic eruptions such as that of Cumbre Vieja (2021) are a reminder that the land is dynamic.

At Timanfaya you feel the faint heat radiating from the ground when you bring your hand close. Volcanic soils and the trade winds favour species such as viper's bugloss, bridal broom and laurel forests.

There are also fossil continental volcanoes: the Campo de Calatrava (Ciudad Real), with maars and lava flows, and volcanic rocks in Cabo de Gata-Níjar. In Cabo de Gata-Níjar the massif is made up of andesitic, dacitic and rhyolitic rocks, and at the Playazo de Rodalquilar the sand is dark because of the volcanic minerals.

La Cala de San Pedro is reached from Las Negras along a coastal path of about 4 km or by sea, and it has a freshwater spring that filters through the volcanic rock.

To visit it, always follow the waymarked paths and respect the closures in force because of gases or rockfalls. On the Teide you need a permit for the last stretch to the peak. Take water, a cap and sun cream: the dark rock multiplies the heat.

11. Underwater treasure: Posidonia and Iberian cetaceans

Forests grow beneath the water of the Balearics: the meadows of Posidonia oceanica oxygenate the water, fix carbon and stabilise the beaches. Mediterranean tapeweed is the longest-lived species in the biosphere, with stems that grow roughly one centimetre a year and leaves up to a metre long.

Between Es Freus (Formentera) and Las Salinas (Ibiza) the meadow extends for some 700 km². In the calm Mediterranean, the smell of salt and of stranded Mediterranean tapeweed is its signature.

Cetaceans are part of the plan too. In the Strait of Gibraltar pilot whales, short-beaked common dolphins and bottlenose dolphins are sighted, as well as sperm whales in transit.

Choose operators with official badges and a code of conduct, who respect the minimum distances and do not chase the animals. When snorkelling or diving, do not touch or step on the meadows and avoid anchoring over the Mediterranean tapeweed: ask about the eco-friendly mooring buoys. The health of the meadows protects the beaches and small-scale fishing.

12. High mountains: life at the limit

Above the forest the radiation is intense, the wind rules and the growing season is short. Plants become cushions, like the piorno serrano, turn into miniatures or grow creeping. Animals adjust their coats, schedules and routes to that tight calendar.

Each sierra has its own version. In Sierra Nevada endemics such as the snow star (Plantago nivalis) grow, and there are routes to the Veleta and the Mulhacén. The Pyrenees have alpine pastures, Pyrenean chamois and bearded vultures in high flight. In Guadarrama the piorno serrano flowers at the beginning of June on the summits, which turn yellow and smell of vanilla, and its highest peak is Peñalara, at 2428 m.

The season runs from July to September in most sierras, with late May and June depending on the snow. Take layers, an IGN map and expect afternoon storms; do not underestimate the distances. These are fragile ecosystems: stepping off the path erodes the ground and opens scars that are hard to close.

13. Working landscapes that endure: dehesas and rice fields

One holm oak every few metres and a grassy floor: that is what a dehesa looks like, an open woodland managed extensively. It is a humanised landscape that maintains biodiversity, and on estates with sustainable management, steppe birds, bats, fungi and pollinators thrive.

In dehesa landscapes, cork and ham coexist with Spanish imperial eagles and booted eagles. The rice fields of the Ebro Delta are agricultural wetlands where 95 species nest and many others rest and feed during migration.

The world's largest population of great bustard is concentrated in Castilla y León and Castilla-La Mancha. It is the heaviest flying bird in the world: males can exceed 16 kg and it reaches 60 km/h.

To visit it, follow signposted routes, avoid off-road driving, buy local products (cheeses, oil, honey) and ask about demonstration dehesas or ecomuseums.

14. Conservation successes: when patience works

The bearded vulture is flying over the Picos de Europa again thanks to coordinated reintroductions. Today there are around 50 individuals in the park and the species is moving towards self-sustainability, with the release of animals expected to be suspended in a few years.

This bird feeds on bones and shells that it drops from great heights to break them against the rocks and swallow them. The Cantabrian brown bear also shows a positive trend: it is spreading across the Cantabrian Mountains, from the Ancares de Lugo (Galicia) to western Cantabria, in two nuclei (western and eastern) with little exchange of individuals between them.

The lesson is repeated in both cases. Protecting corridors and base prey is as key as releasing animals, and local involvement — farmers, reserves, guides — prevents conflicts.

You can help too. Choose operators that contribute to conservation and avoid revealing the locations of sensitive nests. If you are interested in citizen science, take part in responsible programmes, without fine geolocation.

15. Deserts and semi-deserts: when Spain looks like another planet

In Almería, the Tabernas desert is the only hot desert in Europe: it receives around 200 mm of rain a year and its gullies have been carved by torrents. It is protected as a natural area across 280 km² and extends through Tabernas, Gádor, Santa Cruz de Marchena, Alboloduy and Gérgal.

There, maximums exceed 45 °C and can approach 50 °C in the shade, with some 3000 hours of sunshine a year. In Bardenas Reales (Navarra) and Los Monegros (Aragón) you find badlands and cereal steppes with birds such as the pin-tailed sandgrouse, the black-bellied sandgrouse and the Eurasian stone-curlew.

These landscapes break the green-blue cliché of mountains and coast and shelter species adapted to saline soils and droughts. If you go in summer, avoid the middle hours of the day, carry extra water and a hat. Walk on authorised tracks: the clay mud after the rain is a trap. Keep your distance from steppe birds, which are very sensitive to trampling and noise.

Landscapes and habitats you shouldn't miss

Spain is best understood through its great habitats. Rockrose and rosemary accompany the route in many of them, and each one has its keys to visiting it well.

  • Mountains and peaks

The mountains are distinguished by a rapid altitudinal gradient, fossil glaciers, scree slopes and ice-carved lagoons. La Alpujarra takes in the slopes of the southern side of Sierra Nevada and the sierras of Lújar, La Contraviesa and Gádor.

Plan for elevation gains and mountain huts, check the afternoon storms and use signposted GR and PR trails.

  • Coasts and dunes

The coastline is diverse: cliffs (Costa da Morte), estuaries (Galicia), salt marshes (Doñana), sandy bars (Ebro) and mobile dunes (Bolonia, Corralejo). The network of coastal parks and marine reserves shows this dynamism; urban beaches do not reflect it.

In the dunes of Bolonia, the whole western sector of the beach has been a natural monument since 2001. European beachgrass is a pioneer plant adapted to burial that helps stabilise the dune, and the natural advance of the sand over the pines must not be prevented.

Check tides and winds, avoid stepping on the dune vegetation and get up early to see wildlife and avoid the crowds.

  • Islands and volcanoes

Basaltic and phonolitic substrates, fog gradients caused by the trade winds and a high number of endemics mark these islands. El Teide is a volcano of 3,715 m and Timanfaya is a park of volcanic origin; the Anaga massif is a mountain formation in Tenerife.

Cabrera is an island south of Mallorca, owned by the Ministry of Defence and part of the Archipiélago de Cabrera Maritime-Terrestrial National Park since 1991. Its conservation is due to the military presence since 1916.

You need permits for summits such as El Teide, hydration and sun protection, and accredited operators for whale and dolphin watching.

  • Forests and unique habitats

There are humid cloud forests of laurel, cork oak groves with canutos, beech woods with soft soils, juniper groves and Spanish fir forests (Sierra de las Nieves).

Respect conservation closures, do not collect without permission and wear footwear that does not damage soft soils.

  • Rivers, gorges and wetlands

You'll find karst canyons (Hoces del Duratón), river terraces, endorheic lagoons and estuarine salt marshes. Daimiel and Villafáfila bring together steppe and water birds.

Take a telescope for the cliffs, keep quiet in the colonies and do walks or kayak routes with authorised guides.

In all habitats, prepare realistic logistics: access, water, alternatives and weather. Many estates and mountains are communal or private with traditional uses, so say hello, ask for information and share the path with respect.

Spain's biodiversity: endemics and challenges

Spain is one of the European countries with the greatest biological wealth, and a good part of that wealth lives in the Canary Islands and in the Baetic mountain ranges. Its biogeographical position, its relief and its dual continental and island nature explain why.

The Natura 2000 network covers more than a quarter of Spanish territory and protects thousands of species of birds, mammals, reptiles, amphibians and plants. In total, Spain has 7,600 vascular plants, with a high percentage of endemics, especially in the Canary Islands and in the Baetic ranges.

On the islands, isolation has created species of its own: Tenerife blue chaffinches, gallot's lizards and high-summit flora. The Gran Canaria blue chaffinch (Fringilla polatzeki) is endemic to the island.

The buzz of a bumblebee on a high-mountain flower sums up an invisible chain of relationships.

The threats are spread out: habitat loss and fragmentation due to coastal urbanisation and infrastructure, climate change with glacier retreat, heatwaves and water stress, invasive alien species such as the American mink, the wels catfish, the raccoon or aquatic plants, and overexploitation of water in aquifers with diffuse pollution.

There is progress too. Protected areas are being expanded and LIFE projects and recovery plans for the Iberian lynx and the bearded vulture are working. Riverbanks and wetlands such as Daimiel and the marshes are being restored, land stewardship is growing, and a rural economy linked to sustainable products such as cork and extensive sheep farming is being sustained.

To see endemics, choose your spot well. In the Canary Islands there is the laurel forest; in Sierra Nevada, Plantago nivalis and Artemisia granatensis; in the Sistema Central, flowering broom.

Follow a few basic rules: don't use playback with sensitive birds, keep your distance, don't share nest locations and hire local guides when access is complex. Your responsible visit counts if you buy local, reduce your footprint and choose operators that offset emissions and contribute to conservation.

National parks, activities and tips to minimise your impact

Spain has sixteen national parks and each one protects a natural process that is not repeated anywhere else. All of them have good visitor facilities: visitor centres, car parks and signposted trails.

El Teide, in Tenerife, is a dormant active volcano with a sea of clouds and endemic flora. Spring is the best time because of the flowering. The trail climbs from La Rambleta to the summit and some sections require prior authorisation.

Doñana, in Andalusia, has dynamic marshes, lynx and birds; the best peaks come during migration. Picos de Europa, between Cantabria, Asturias and León, includes the largest limestone formation in Atlantic Europe. In Ordesa y Monte Perdido (Huesca) you'll find glacial canyons, autumn colours and waterfalls.

Timanfaya, in Lanzarote, shows a recent malpaís with routes regulated because of the fragility of the terrain. Aigüestortes (Lleida) brings together more than 200 lakes or estanys, crags such as Els Encantats and high-mountain meanders; go in summer and early autumn. Sierra Nevada (Granada/Almería) keeps the highest summits on the peninsula, with summit flowers in June-July.

You can go signposted GR/PR hiking, guided traverses and ascents. You can also watch wildlife from viewpoints and hides, and practise ethical photography. There is kayaking in wetlands and estuaries, snorkelling where compatible and whale watching with accredited operators.

Get up early and avoid peak times: many car parks fill up early. Take water, food, layers and a headtorch, as well as offline maps and an extra battery. When choosing an operator, ask about certifications, group ratios, insurance and contribution to conservation.

Frequently asked questions and planning

Do I need permits to enter or camp in protected areas?

In most national and natural parks you can enter freely along public paths and trails. There are areas with a quota or prior booking to protect fragile habitats, so it's worth checking the regulations before you set off.

In El Teide National Park, the final trail (PNT 10 Telesforo Bravo) requires a time-slot booking. In Doñana, some itineraries and accesses are regulated. Special Areas of Conservation (SAC) and Sites of Community Importance (SCI) may have their own rules on transit, dogs on leads or climbing.

Camping is usually prohibited in national parks. Bivouacking may be allowed above certain altitudes or in time slots in some natural parks, but you always have to check the regional regulations.

To find out and request permits, go to the official website of the park or the regional government, in the public use section, and check the signs at visitor centres and car parks. Plan ahead on long weekends and at weekends, because quotas run out. Respect the signs, don't improvise overnight stays and keep your booking receipts on your phone to avoid fines.

What precautions should you take in the mountains, on the coast and on the islands?

AEMET's forecast by district and altitude determines the kit you put in your backpack. Check it the day before and adapt your clothing and equipment to the route you're going to do.

In the mountains, take layers, a windproof and a thermal, boots, water, a headtorch, a first-aid kit, an IGN map and a reliable track. Prepare a plan A and a plan B, set a return time and let a contact know. Calculate times by the elevation gain and the terrain, not just by the kilometres, and check the snow reports if there are still snowfields.

On the coast and dunes you need sun cream, a cap and water. Check the winds, levante or poniente, and the tides, and don't go into rip currents.

On the islands, pay attention to the calimas, the radiation and sudden changes in wind. If you go up a volcano, wear sturdy shoes and apply for the permit when required.

With wildlife, keep a safe distance from large ungulates and don't go near nests or young. In fog or a storm, come down off the ridges and avoid isolated trees and exposed areas.

If there's an emergency, call 112 and give your coordinates in latitude and longitude or in IGN UTM. And don't force the goal: the summit can wait.

When is it ideal to visit each ecosystem?

In Spain every ecosystem has its window: high mountains call for summer and marshes for the migrations. Choose the date according to what you want to see and not the other way round.

In the mountains, from late June to September for high mountains; May-June and September-October for mid-mountains and to see the colours of the forest. In wetlands and marshes, March-May (pre-nuptial passage), September-November (post-nuptial) and December-February for wintering birds. On the coast and dunes, spring and autumn to avoid the heat and the crowds; winter for storms and seabirds.

The islands can be visited all year round; in the Canaries the flowering on the summits comes in May-June, and it's best to avoid intense calimas. To watch birds, go at dawn and at dusk and at the migration peaks; take a guide and a tripod. If you go hiking, set off on weekdays and in the first hours of the day; in summer, get up early. For diving and snorkelling, look for clear, calm waters in summer-autumn and don't anchor over the Posidonia.

The smell of earth after the first autumn rain marks the moment to return to the forest. In high season, book in advance in the most famous parks and use public transport or the shuttle buses where they exist.

How do I get around and where do I stay while respecting the environment?

Moving less and better reduces your footprint and also the stress of the trip. Before choosing a destination, look at what transport there is and how many kilometres you're really going to cover.

For long journeys, prioritise trains and regional buses and combine them with local taxis or a bike for the last stretch. If the valley has no public transport, share a car and park in designated areas. On islands, consider ferries and public transport and avoid unauthorised tracks.

Sleep in rural houses and agrotourism establishments that buy locally and manage waste and water. Eco-lodges with renewable energy and good practices are another option. Use authorised campsites and motorhome areas and don't spend the night freely outside the regulations.

When choosing operators, ask about certifications, small groups, insurance and contribution to conservation. Read the codes of conduct for each activity, especially for cetaceans, birds and caving. On Picuco you can browse activities by region and theme and compare options using sustainability criteria.

Conclusion

In just a few days of travelling, Spain goes from changing climates to glaciers, shifting dunes, marshes, ancient forests and unique endemic species. There are also conservation projects that work, and that changes the way you travel through them.

Before you set off, choose the season and confirm the necessary permits. Travel light and leave the place better than you found it.

To plan, use official maps, check the AEMET forecasts and go to the visitor centres to get up-to-date routes. To move from reading to action, look for responsible guided activities and support the rural communities that keep these landscapes alive.

The key to the getaway is to travel at your own pace and with respect.
