Autumn in the forest: colours, calm and paths that invite you to stop
Between late September and November, beech, oak and chestnut forests dye hills and valleys in ochre, red and gold for a few days. The crunching of leaves under your boots sounds like rest.
This guide brings together ten forests in Spain with their location, their best dates and their access points, and explains why each one deserves a visit in autumn. There are three families of forest, each with its own colour calendar: beech forests (Fagus sylvatica), oak forests (Quercus robur, petraea or pyrenaica) and chestnut forests (Castanea sativa).
To plan your day, the guide tells you how to arrive by car or by public transport, where to sleep nearby (rural houses, paradores, campsites) and what to bring for a full day. On marked routes, PR is Small Route (10–50 km) and GR is Great Route (50+ km), a useful reference for choosing an itinerary safely.
Before setting off, check the weather forecast and respect the signage: close the gates, do not stray from the paths and take your rubbish with you.

Where they are and when to go: keys to choosing your autumn forest
In Spain, the type of deciduous forest depends on the climate. The north and the mountains concentrate beech forests, with long autumns and leaves that turn from green to copper.
The plateaus and the temperate mountain ranges hold oak forests, which withstand drought better and change colour later. In cool valleys with deep soils, large chestnut forests grow, the first to announce the season.
In nearby villages, the smell of early firewood warns that the chimneys are already lit. Choose the beech forest if you are looking for mountains and humidity, the oak forest if you prefer open mountain ranges and the chestnut forest if you want to see the leaf fall sooner.
The season runs from late September to mid-November, depending on the altitude. Check the condition of the trails and book accommodation in the local villages in advance: October weekends fill up.
Mind map: regions and forest types
Spain brings together beech forests, oak forests and sweet chestnut forests in four large mountain zones. This quick guide helps you choose a destination depending on the tree you want to see and the region you are travelling to.
The humid north (Navarra, País Vasco, Cantabria) is a land of beech and mixed beech and fir forests. There you will find the Selva de Irati (Navarra), the Gorbea Natural Park (Bizkaia/Álava) and the Saja-Besaya natural reserve (Cantabria). In the Pyrenees and the Pre-Pyrenees (Navarra, Aragón, Cataluña) the beech forests occupy north-facing slopes and ravines.
The Cantábrica (Asturias, León, Lugo) mixes beech forests with extensive oak forests and has Muniellos (Asturias) as its emblem. There are also patches of sweet chestnut in valleys such as Ambroz (Extremadura) and Ancares (Lugo/León). In the Sistema Central (Guadarrama, Gredos, Sierra de Ayllón) relict beech forests grow, such as Tejera Negra, and powerful sweet chestnut forests like El Tiemblo, on north-facing slopes at mid-mountain altitude.
Castilla y León adds wide oak forests and local beech forests like the Faedo de Ciñera (León) and the Busmayor Beech Forest (El Bierzo). The north of Extremadura preserves classic sweet chestnut forests like Hervás (Valle del Ambroz) and San Martín de Trevejo (Sierra de Gata), with chestnut festivals in autumn.
If you want accessible sweet chestnut forests with living traditions, aim for Ambroz (Cáceres) or El Tiemblo (Ávila). For iconic beech forests, go to Irati (Navarra) or Tejera Negra (Guadalajara).
Inside the sweet chestnut forest, do not stray from the paths to avoid soil compaction and do not climb the trees.
Colour calendar: altitude, climate and the “golden week”
Autumn paints the forests in waves: first the high mountains, then the mid-altitude, and from north to south. A light frost and mild days with cold nights accelerate the palette.
The general window goes from late September to late November. Each type of forest has its moment, and altitude rules.
- Beech forests, between 1,000 and 1,600 m: the peak arrives between mid-October and early November in the north and in the mountain ranges.
- Oak forests, between 800 and 1,400 m: the peak is slightly later, from late October to mid-November.
- Sweet chestnut forests, between 500 and 1,200 m: early-mid colour, from early or mid-October to early November in temperate valleys.
As a practical rule, for every 300–400 m of ascent, the colour arrives 5–7 days earlier. Orientation also matters: north-facing slopes (north) turn earlier and maintain the colour longer, while south-facing slopes (south) change later and the leaves fall sooner, especially after dry winds. Autumn mists stabilise the colour; storms of rain or strong wind can cause leaves to fall within 24–48 hours.
To get it right, follow the networks of parks and town halls, which publish the "colour status" and visitor numbers. Check the 5-day forecast and the wind: gusts exceeding 50 km/h signal leaf fall. Book flexible accommodation for 2–3 possible weekends to "hunt" the golden week. And keep a plan B nearby at a lower altitude if a front brings the leaf fall forward at high altitudes: sometimes, 300 m below, the forest is still ablaze.
Arriving and staying: transport and accommodation near the forest
Almost all of these forests are next to small villages, with access via local roads and a final stretch via track or path. It is advisable to plan for that final stretch on foot or by track, with suitable footwear and enough time.
The nearby villages are the usual base for visiting them, so look for accommodation in them. Book in advance if you are going in autumn, when more people head up to the forest.
How to get there: car, train and the final stretch
Having your own car or a rental gives you the flexibility to adjust schedules and avoid peak times from the large cities. The local roads are well-signposted, but the last 2–10 km can be narrow and bumpy. Download offline maps: coverage fails in valleys.
In high season, there are regulated parking areas with reservations or fees on peak days in Tejera Negra, El Tiemblo and Irati. It is advisable to arrive early, between 8:30 and 9:30.
The train does not reach all forests. Muniellos can be reached from Cangas del Narcea by regional bus (bus + taxi), car or taxi; there is no train service. Irati can be accessed by bus (Pamplona-Ochagavía line) or by car; Ochagavía has no train station. El Tiemblo can be reached from Ávila by regional bus (Autocares Grupo Samar, ~58 min); there is no train option.
Check "nearest station + name of the forest" and coordinate with a rural taxi for the final stretch. Baby carriers and walking poles make muddy and root-filled sections easier. Ask about boardwalks or compacted tracks: some visitor centres lend all-terrain wheelchairs upon reservation.
Avoid traffic jams by planning your route in reverse: photography first and a walk afterwards. If there is a capacity limit, confirm on the park or town hall website.
Where to sleep: rural, camping and paradores
Sleeping next to the forest allows you to enter with the first light and avoid the busiest hours. In autumn, additionally, the night in the valley is part of the trip.
When booking, ask about early breakfast and whether they serve light dinners late at night.
Campsites and bungalows open selectively in autumn: confirm opening times before booking, as some offer heated cabins. If heavy frost or intense rain is forecast, consider whether the accommodation has covered parking. Autumn has high demand on weekends, so book 3–6 weeks in advance.
Indicative prices to help with your calculations:
Respect silence hours, avoid intense outdoor lights and follow local recycling rules. Shop in the valley's shops and markets: that spending supports the network that looks after paths and mountains. If you want to combine a beech forest and a sweet chestnut forest in the same trip, create two different bases: you will save kilometres and gain sunrises.
Ten forests that burn with colours: essential beech, oak and sweet chestnut
In autumn, the golden light pierces through the canopy and draws dust in suspension. It is the best time to explore the forests of Spain, and here are ten.
The selection balances tree type, accessibility and natural value. There are beech forests, oak forests and sweet chestnut forests spread across the Spanish geography, with options for all hiking levels.
Each forest has its moment: the colour changes according to the altitude and the species. Check the autumn status before setting out and book accommodation in the most visited areas.
1. Montejo Beech Forest: autumn a stone's throw from Madrid
An hour and a half from Madrid, in the Sierra del Rincón, the Montejo Beech Forest is one of the best options to see autumn without moving far from the capital. The forest grows at the southern limit of the Iberian distribution of the European beech and forms a cool space among oaks and birch. One of its specimens, the "de la Roca" beech, is over 250 years old, and the beech forest is a UNESCO World Heritage Site.
Visits have limited capacity and prior booking is mandatory during high season through the Ministry of Environment of the Community of Madrid. If you are going to take photos, look for the light from 09:30 to 11:00 and from 16:30 to 18:00: after a light rain, the colour saturates. Avoid tripods on narrow paths during peak hours.
Bring boots with gripped soles for the mud, a lightweight raincoat and layered clothing. You can combine the visit with villages in the Sierra del Rincón such as Horcajuelo and Prádena, with crafts and simple bars.
2. Irati Forest: the beech-fir forest that never ends
The Irati Forest comprises about 17,000 hectares of continuous forest mass in the Navarrese Pyrenees. It is one of the most extensive and best-preserved beech-fir forests in Europe.
Car parks are regulated with a fee during the season and there are bridges; the signage is clear.
The Irabia Reservoir Route is circular, 10–14 km long via local PR-NA paths, with 80 m of elevation gain. The forest is reflected in its still banks. You arrive by car from the Mendilatz diversion towards Irabia, passing the Information Point and the Arrazola customs. There are two small car parks, so it is advisable to get up early. Vehicle access to Irabia is regulated to avoid traffic congestion on the paved road.
With children, the Route of the Senses is easy and measures 2–4 km.
Do not leave the marked path, respect the fenced regeneration areas and do not collect leaves or mosses: it is a sensitive habitat. There is a high influx on weekends, so arrive early or go during the week. Pyrenean weather calls for thermal layers, thin gloves and a headlamp for the short afternoons.
3. Tejera Negra beech forest: a tale of mists and colours
In a glacial valley in the shadows of the Sierra Norte de Guadalajara Natural Park, European beech trees grow at an unusual latitude. The Tejera Negra beech forest is one of the few beech forests so far south, and in autumn, it goes through a palette of reds that is not seen in other forests.
The Robledal Path starts from the visitor centre. The Carretas Path is 6.5 km with white and blue markers and a very varied mosaic of colours. The Robledal Path is 17 km with green markers, demanding, with a wide view of the beech forest and the adjacent oak forests. If you want both, there is a combined 20 km route that links the Robledal Path with the Carretas Path and passes by the Matarredonda viewpoint and the charcoal burner's hut.
Days with high clouds provide a soft light ideal for the red tones. To avoid crowds, arrive before 09:00 or enter after 15:30 for short routes, and prioritise Monday to Thursday.
Access is via Cantalojas and the final track is accessible by tourist vehicles. In autumn, parking requires a reservation. The access hours are from 10:00 to 15:00 and you must leave before sunset; the space reservation is valid until 13:00 on the day of the visit.
For the Robledal Path, you can park in the visitor centre car park without reservation or size limits. For the Carretas Path, use the internal car park (Casarejo), which cannot be entered by buses with more than 35 seats.
Check the snow reports: the first snowfalls can arrive at the end of October at high altitudes. With heavy rain, carry poles and gaiters due to the slippery clays on the paths.
4. Ciñera Faedo: small, ancient and nearby
The Ciñera Faedo, in León, is small, ancient and nearby.
The circular route measures 4.5 km, is of easy difficulty and takes 2 to 2.5 hours to walk along a path equipped with wooden walkways.
After a light rain, the moss and the leaves look varnished. For photography, look for low focus with leaves in the foreground and carry a small tripod for the wide walkways.
The path was promoted by neighbours and local entities: respect the walkways and close the gates. You can combine the visit with La Pola de Gordón or with a tasting of cured meats and Bercian broth.
From León capital, it takes 40–50 min via national and local roads.
5. Peloño beech forest: endless slopes
More than 1,500 continuous hectares of European beech and oak cover the slopes of Peloño, in the Ponga municipality. The forest surrounds Collado Les Bedules and Arcenorio, between 400 and 1,500 m above sea level, with English holly, common juniper in the high areas and bilberry.
The first section has a wooden walkway accessible for strollers and people with reduced mobility.
The Les Bedules – Arcenorio route is long and of very high difficulty, only for prepared hikers. The track ascends to Collada Güaranga and leads to the Roabín stream and the Arcenorio valley.
The Cantabrian weather changes quickly: bring a waterproof jacket and a thermal layer even if the forecast is mild. To take photographs, get up early to avoid the low mists and look for soft backlighting next to the clearings on the track.
To get there, take the PO-2 road from San Juan de Beleño towards Viego to Collada Llomena, where a track turns right towards Les Bedules. There is an area to leave your vehicle and continue on foot or by bicycle. The roads are mountain roads: take them slowly and park without blocking the entrances to forest tracks, which are service roads.
Peloño is perfect if you like walking without rushing and seeing autumn in large format, with slopes carpeted to the horizon.
6. Muniellos forest: the kingdom of oak in silence
Only 20 people are allowed into Muniellos per day. The Integral Natural Reserve protects one of the best-preserved oak forests in Europe and limits access to safeguard its balance.
The forest extends between the Cangas del Narcea and Ibias municipalities and includes the Muniellos, La Viliella and Valdebois mountains, with altitudes between 680 m and 1,640 m (Candanosa peak). It is a primeval oak forest with little intervention, with a diversity of Quercus and discreet fauna; it is home to at least 160 species of Asturian fauna. The smell of dry oak leaves has a hint of walnut.
Book your permit months in advance during the season. Entry and exit are done exclusively through the Tablizas Centre, the entrance and control point of the reserve, which closes from 1 to 6 January and on 24, 25 and 31 December.
You have two routes. The Lagunas Route is circular, 18–20 km, demanding, with sustained ascent and absolute silence; it is not accessible for strollers or people with reduced mobility.
The full colours of autumn arrive from late October to mid-November if there are no strong storms. It is a route only for hikers in good shape, due to the notable elevation gains and length. Bring food and water for the whole day, as there are no services on the route.
7. Ancares oak groves: living landscapes among pallozas
Between Lugo and León, the Ancares hold oak groves, sweet chestnuts and patches of European beech in narrow valleys, with pallozas and teitos as traditional architecture. In autumn, the colour of the leaves changes at the same time as the stone landscape.
In Piornedo, 14 pallozas are preserved, declared a Historical-Artistic Site since 1931. The Casa do Sesto, an ethnographic museum, shows the central fire, farming tools and original beds; it has no fixed schedule, so ask in the village before heading up. Walking through the village and among the pallozas is free.
In the surroundings, horses and cachena cows, an endangered native breed, graze. The Piornedo – Lagos de Villouso route is demanding and offers views of the entire massif, between Lugo and León.
Local viewpoints towards the Ancares Valley follow one another on cliffside roads. For photography, head up to the high roads at sunrise, when layers of mist step over the oak groves.
The weather changes abruptly, so bring a windbreaker and a second layer. You can visit ethnographic museums and pallozas, and buy honey and chestnuts from the valley.
8. El Tiemblo sweet chestnut grove: giants with history in Gredos
At the foot of Gredos, in El Tiemblo (Ávila), centennial sweet chestnuts grow alongside comfortable paths for going with children. It is one of the great sweet chestnut groves in Spain due to its easy access, its monumental trees and the living tradition of the sweet chestnut.
"El Abuelo" is a sweet chestnut tree of more than 500 years that summarises centuries of relationship between the people and the mountain. The circular route measures 4.4 km, is easy and works well with children; along the way there are marked diversions to unique trees and viewpoints. The leaf litter crunches like tissue paper.
The colour arrives from the beginning to the end of October, depending on the autumnal warmth. Among the sweet chestnuts, discreet birds such as woodpeckers and Eurasian jays can be seen, and in the nearby villages there are tastings and fairs according to the municipal calendar.
Access is regulated from 10 October to 31 December 2026, with advance booking on Saturdays, Sundays and holidays. The shifts are from 8:00–11:30, 11:30–15:00 and 15:00–18:30 h, with a limit of 35 vehicles per shift.
- It costs 6€ per car plus 2€ for each companion.
- You can only enter in a private vehicle: there is no access on foot or by bus this season, and the car park is in El Regajo.
- From Monday to Friday, it is advisable not to go up due to logging and supply works on the path.
- During long weekends there is high attendance, so go during the week and in the early hours.
Bring footwear with good grip for the mud and clothing in layers. Do not pick sweet chestnuts without permission or outside private reserves.
9. Hervás sweet chestnut grove: long autumns in the Ambroz Valley
The Hervás sweet chestnut grove occupies temperate slopes on the foothills of the Béjar mountains, north of Cáceres, and has a mild and long autumn. It is one of the most important and best-preserved sweet chestnut forests in southern Europe.
The air smells of roasted sweet chestnut and wet rockrose.
The Sweet Chestnut Route starts from Hervás: a 5 km circular route, of easy-moderate difficulty, with wide tracks and shade. During the route, you will see five centenarian sweet chestnut trees about 700 years old in Casas del Castañar, declared Singular Trees by the Junta de Extremadura. To preserve them, do not approach the trunk or the roots.
If you go with a camera, look for the intense golds at sunset on the western slopes and use a polariser to reduce glare on the leaves.
On the table, there are migas, cured meats and sweets with sweet chestnut; eating early avoids waiting. You arrive via good roads from the A-66, with parking in the village and signposted walking exits. Hervás combines forest, a charming village and an autumnal agenda for families and groups of friends.
10. Oma Forest: art and landscape in Urdaibai
In Kortezubi (Bizkaia) there is a painted forest: the Oma Forest, recreated and reopened in a new location within the Urdaibai Biosphere Reserve. There, art and nature go together.
The trees have paintings that, from certain positions, form geometric, human and animal figures. The route is designed so that you align those figures with your gaze.
Around it there are pine forests and mixes with oak and sweet chestnut that provide autumnal colour. Oma offers a different autumn: less sea of leaves and more dialogue between art, trees and Basque forestry tradition.
The itinerary is signposted and on peak days there is capacity control, so check the local regulations before going.
Do not touch the paintings and respect the markers and the rest areas. The best light to see the colours arrives with cloudy skies, without glare.
What to do among golden leaves: routes, viewpoints and useful tips
In autumn, the light fades early in the forest, so it is advisable to choose your route according to your level and set off with plenty of time. Here you have options ranging from 2 to 9 hours, ideas for photography and wildlife watching, and what you cannot leave out of your backpack.
The Castañar circular route starts from the El Regajo Recreational Area. Pets on a lead are allowed.
The best light for photography arrives 30–90 min after sunrise and before sunset, and overcast skies saturate the colour. Look for soft backlighting through the canopy, leaf details against dark backgrounds, and reflections on thin sheets of water like Irabia. A mobile phone with RAW mode or a lightweight camera, a polariser, and a microfibre cloth for droplets are enough.
Get up early and keep silent to see Eurasian jays, woodpeckers and roe deer, and in the Cantabrian region, look out for wild boar signs. A pair of lightweight 8x32 binoculars is sufficient, and it is not advisable to follow tracks off the path. Regarding mushrooms, ask for permission if there are mycological reserves and respect municipal quotas: cut with a pocketknife, carry an airy basket and do not disturb the leaf litter. Do not collect chestnuts on private estates, as many chestnut groves are local community property.
In your backpack, you must have waterproof footwear with good grip, a thermal layer and a waterproof jacket, water (1–2 l per person), energy food, an offline map and a power bank; on long routes, add a basic first aid kit and a thermal blanket. Inform someone of your route and return time, step on mud without creating new tracks, and keep dogs leashed in areas with livestock or sensitive wildlife, always picking up their droppings.
A well-planned full day would look like this: main route in the morning with low light, lunch in the village and a visit to an interpretation centre at midday, and in the afternoon a short walk to a nearby viewpoint and local shopping (honey, chestnuts, cheeses). Allow for a time margin: light fades earlier in narrow valleys and the walk back to the car can take longer than expected on muddy paths.
Frequently asked questions
When is the best time to see autumn in the forests of Spain?
The exact date depends on the type of forest and its location.
The "golden week" arrives 5–10 days after the first light frost. To refine the date, check the social media of parks and town halls and avoid days with strong wind gusts, which blow the leaves off. If you can, block out two weekends to hit the peak moment.
Do I need permits or bookings to enter these forests?
It depends on the space and the season. Most public mountains allow free visits via paths, but several forests regulate access in autumn for conservation and safety reasons.
Muniellos requires a very limited daily permit, which must be requested months in advance. During high season, there are parking lots with reservations or fees in Tejera Negra, the Selva de Irati and the El Tiemblo Chestnut Grove.
Official guided tours help you understand the forest and, in places with quotas, guarantee access in specific time slots. It is advisable to book them in advance, especially during bank holidays.
Book in advance before setting off: in autumn, weekends and bank holidays get busy.
What basic equipment should I carry for an autumn hike?
In autumn, the ground is wet and the afternoons get shorter: prepare your backpack with mud and light in mind. Dress in layers and wear waterproof boots with gripped soles. Bring spare socks, a thermal layer, and a lightweight raincoat.
If the route reaches 1,200 m or more, add a hat and thin gloves. For short afternoons, pack a headtorch with batteries, an offline map, and a power bank.
For photos, use your phone in RAW mode or a lightweight camera, with a cloth for droplets and a polariser. Bring energy food and water (1–2 l per person); on long routes, add a first aid kit with bandages, adhesive tape, and an emergency blanket.
With families, pack an ergonomic carrier, a rain cover for the backpack, and wipes. If you are going to take photos, add a mini tripod and a lens cover. On long hiking routes, take poles, gaiters, and an extra layer.
Is it safe to visit with children and pets?
Yes, with a sensible choice of routes and some basic guidelines. Choose easy itineraries, 2–6 km long with little elevation gain, and plan stops every 45–60 minutes. Bring snacks and extra layers of clothing.
On boardwalks and embankments, hold the child's hand and maintain continuous attention. With children, limit the outing to 2–3 hours depending on age and temperature. Mud can make children cold: keep a change of dry clothes in the car.
Dogs must be kept on a lead in many areas, especially in zones with livestock, reserves, or sensitive fauna. Check local regulations and avoid letting them loose in beech forests with delicate soils. Avoid unknown mushrooms and fruits, and set a meeting point if someone gets ahead.
Where can I find updated information on the state of the forests?
Before setting off, check what natural parks, environmental departments, and town halls publish: capacity notices, colour status, and specific closures due to wind or snow. Valley and regional tourism offices provide daily reports on attendance and last-minute recommendations.
On social media, the official profiles of parks and provincial councils share recent photos of the state of the forest. Reliable hiking apps have PR and GR tracks with updated reviews.
Always check the weather forecast and alerts for fires or adverse phenomena from AEMET before setting off. If you have doubts about access, fees, or bookings, call or write to the tourism office before leaving.

Conclusion
Autumn in the forest doesn't last long: the colours change every week, so choose your destination and set the date as soon as possible. The soft afternoon light brings brightness to every leaf.
Book your accommodation in advance and prepare equipment in layers. Have a nearby plan B ready in case the wind causes the leaves to fall early at high altitude.
If you travel as a family, look for easy objectives and set off early. If you walk more, calculate the light and the elevation gain realistically.
Upon returning, share your photos and a review of the forest: it helps other travellers and those who look after these mountains.
