Why Bilbao is a perfect base for walking
In less than an hour, you go from the tram to the trail, which makes Bilbao a very practical base for walking. Between the estuary and the Cantabrian Sea, there are cliffs, beaches, marshes, and gentle mountains, with very different landscapes at short distances.
The levels are balanced: family walks of 2–3 hours, half-day trips with moderate elevation gain, and a classic mountain route that requires a bit more physical fitness.
You can fit a route into a morning with a seaside lunch afterwards or dedicate a weekend to the coast and the mountains. Rounding a headland, the salt spray on your face and the dull thud of the waves against the rock accompany the path.
Before setting off, check the forecast and have an alternative ready: in Bizkaia, the weather changes quickly and the sea or fog can make the plan tougher. For meteorology, AEMET and Euskalmet/MeteoEuskadi are useful; to get around, use Metro Bilbao, Euskotren, and Bizkaibus.

The essentials: climate, seasons and how to get there from Bilbao
In Bizkaia, distances are short and public transport reaches almost the entire coastal strip. This means you can consider a one-day route from Bilbao without a car and without waking up too early.
Spring and autumn are the best seasons due to mild temperatures and fewer people. In summer, the beaches invite you to swim, but it is advisable to get up early to avoid the heat and crowds, and you must be extremely cautious on the cliffs due to the heat and trail traffic.
The flysch requires you to watch the tide. With high tide, some areas become flooded, and with high coefficients, the difference in level is at its maximum. Check the tide tables for the Basque coast and avoid venturing onto the beach if the tide is rising. Flysch means the rhythmic alternation of hard and soft layers formed on the seabed, now exposed and eroded like a stone book.
Wear hiking boots with grippy soles for the coastal rocky terrain and the mud after rain. Add a lightweight waterproof layer for all year round, because the north wind can pick up suddenly with sudden squalls. Don't forget water (1–2 l depending on temperature), a cap, sun protection, and a salty snack.
By car from Bilbao, Sopela is 19 minutes away; Bakio, 28–35 min (29 km); Bermeo, about 35 minutes (34 km); Zumaia, 60–75 min; La Arboleda, 25–35 min; and Monte Oiz, 44 minutes (42 km). Euskotren towards Zumaia and Deba, on the Bilbao–Donostia line, takes approx. 90–110 min depending on the stop; confirm schedules as there are variations due to works. Bizkaibus brings you to Bakio and Bermeo for Gaztelugatxe: in summer, line A3517 operates, and during Holy Week, the A3524, with more services in summer, Holy Week, long weekends, and high season. Outside of the tourist season, the service between Bakio and Bermeo only runs from Monday to Friday.
On the coast, keep your distance from the edge: the sandstone and clays crumble with the rain. In the flysch and in enclosed coves, enter and exit only with the tide going out and with enough time margin to return via the top if necessary. The sea breeze brings the smell of seaweed to the coastal ridges, and a gust of wind can change the thermal sensation in minutes.
Check AEMET and Euskalmet the day before and on the day itself, and have an alternative urban plan ready if the weather gets complicated.
Where to sleep: Bilbao, coastal towns and rural houses
Choosing a base sets the pace for your getaway: Bilbao offers urban comfort and connections, the coastal towns place you at the foot of hiking trails, and the countryside provides rural calm. If you are travelling without a car, Bilbao is practical: hotels and B&Bs are well connected with Metro Bilbao, Euskotren and Bizkaibus; returning from a route and having dinner in the Casco Viejo or Ribera is a plus. If you have a car, sleeping near the routes saves transfers at dawn and makes it easier to park before peak hours.
-
Bilbao (urban hub):
-
Ideal if you combine museums, bars and short walks (Artxanda, Plentzia–Gorliz, Sopela–Barrika).
-
Frequent connections to the coast and Urdaibai without worrying about parking.
-
-
Recommended coastal towns:
- Sopela and Plentzia: quick by metro, perfect for linking Bilbao coast trails, surfing and beach restaurants.
- Mundaka and Bermeo: gateways to Urdaibai routes, marshes and excursions to Gaztelugatxe; a maritime atmosphere and taverns with grilled fish.
- Zumaia: strategic base for the flysch, with marked trails and guided tour options of the geopark.
-
Rural near Urdaibai and Gaztelugatxe:
- Farmhouses and guesthouses in Busturia, Gautegiz Arteaga or Kortezubi; tranquillity, easy parking and short access to marshes and beaches.
- Criteria for choosing: proximity to train/bus stops if you do not drive, parking in high season, dining options within walking distance and nocturnal noise in summer.
Booking tips:
- For July–August and bank holidays, book 3–6 weeks in advance and confirm cancellation policies.
- On sunny weekends, beach and Gaztelugatxe car parks fill up early; if you stay overnight nearby, start before 9:00.
- If you are looking for silence, ask for an interior room or one with double glazing in areas with summer evening strolls.
Waking up to distant bells and the smell of freshly baked bread in a farmhouse adds a layer of calm that sets the tone for the day. Find a balance between logistics and atmosphere: moving less and walking more almost always wins.
Eight routes to fall in love with the coast and the mountain
Sopelana – Barrika: cliffs, beaches and coastal path
The Sopelana – Barrika path connects Atxabiribil/Arrietara beach and Barrika beach via a high path, between cliffs, wild beaches and nearby viewpoints. It is 6–9 km round trip depending on the descents you take, with low difficulty and some short climbs.
The stairs providing access to the beaches should be descended with caution. The area is notable for the Bizkaia Flysch, with great geological and landscape value, and the side light of the sunset highlights its textures at low tide. The smell of salt and sand in your trainers accompany every climb from the beach to the high path.
Barrika beach has been a setting for the series "Game of Thrones". If you come to surf, you will find powerful waves with NW swell: respect the flags and the currents. Do not go down to the platform if the tide is rising and avoid unstable cliff edges after rain.
You can do variations: a circular route linking with Meñakoz or short family routes focused on the viewpoints. The starting point is the Atxabiribil beach car park; the Barrika Beach car park is free and the car parks fill up quickly, so arrive early.
San Juan de Gaztelugatxe: climb to the islet and views
A narrow isthmus, 241 steps and a chapel facing the Cantabrian Sea: San Juan de Gaztelugatxe is a hiking classic near Bilbao. The roar of the sea echoes under the arch while the wind gusts between the stones of the staircase.
The route lasts between 1.5 and 2.5 h. The difficulty is moderate due to the elevation gain and the terrain, which can be slippery, and the steepest slopes occur on the return leg.
During high season and on weekends, a free reservation with a time slot may be required: capacity is limited to 1,462 people per day. Controlled capacity is in place during Holy Week, weekends and holidays from May to October, and from 15 June to 20 September, between 09:30 and 19:00 h (until 17:00 h from late October). Access to the stairs may be temporarily closed for maritime safety or construction works.
It is advisable to avoid 24 June, 31 July, 29 August, 31 August and 30 December due to local celebrations. To avoid the crowds, arrive before 09:00 or late in the afternoon; on days with heavy swells, the views are more dramatic from the high viewpoints. Keep your distance from the edge and do not approach the waves on the bridge if the sea is rough.
By car, you can reach it via the BI-3101 between Bakio and Bermeo; by public transport, there are Bizkaibus buses to Bakio or Bermeo and a short taxi ride, so check the current schedules before setting off.
Urdaibai – El Puntal and Laida: marshes, birds and beaches
In Urdaibai, a UNESCO Biosphere Reserve, walking along its shores lets you see tides, waders and dunes. The air smells of salt and damp mud while a group of Kentish plovers takes flight low over the ground.
The estuary is a great place for birdwatching: waders, great herons and, during migratory passage, osprey. In spring and summer, birds that return from southern Europe and Africa nest in the Atlantic countryside and the reed beds.
Go in spring or autumn and with mid-to-low tide to see them in the mudflats. The estuary interpretation centre is a living museum dedicated to the world of birds and their migrations; confirm opening hours before your visit.
Respect the nesting areas and the signage, and do not step on dunes or salt marshes. Laida is 4 km from Bermeo; from Bilbao, take the A-8 (Gernika exit), the BI-2235 and the BI-3234 towards Elantxobe (52 km, 55 min).
By bus, you have the Bizkaibus A3518 or local lines from Gernika; outside of season, the frequency is 2-3 services daily. There is dirt parking in the Renteria neighbourhood (end of Huarte kalea), outside the blue paid parking zone.
Zumaia – Flysch route: geology and viewpoints
In Zumaia, you walk upon a stone book: hard and soft layers that preserve millions of years.
It is 14–16.8 km and 2.5–3.5 h with low-moderate difficulty, featuring stairs and irregular sections. In those layers, extinctions and climate changes can be read, and the Basque Coast Geopark covers Zumaia, Deba, and Mutriku, with a geological sanctuary linked to the extinction of the dinosaurs.
The sharp rock crunches under your sole as if you were stepping on dry stone leaves.
You can arrive without a car: Euskotren connects Bilbao with Zumaia and the station is a 12 min walk from the Itzurun Flysch. From there, follow the Basque Coast Geopark signage. By car, park in the village and walk 10–20 min to Itzurun to avoid coastal congestion.
Walk across the rocky platform only with low tide and calm sea, and check the tide tables and the weather. With high tide, use the viewpoints and the high path. During the season, there are guided geopark tours and an interpretation centre in Zumaia with clear panels; bookings are made at geoparkea.eus.
Artxanda Mountain: urban viewpoint and easy route
From above, the murmur of the city rises muffled while a cool breeze stirs the tops of the plane trees.
You can combine the funicular and the path: go up in the Artxanda Funicular and walk down via the marked path to Bilbao, or do it the other way around to finish with the views. The route measures 3–6 km depending on the layout.
The Artxanda Funicular departs from the Funicular square, next to Castaños street, with a frequency of 10 to 15 minutes. On foot, there are different marked access points from Deusto and Castaños.
Go at sunrise or sunset, when the low light highlights the meander of the estuary; avoid the middle hours if it is hot. For families, there are sections of stairs and a comfortable path: bring a lightweight pram only if you are doing a round trip via asphalt or park.
Ganekogorta from La Arboleda: classic mountain route
Ganekogorta (998 m) is a wide summit in Alonsótegui, Bizkaia, with views of the estuary and green ridges.
The difficulty is moderate and sustained, without noteworthy technical sections, although the terrain can become muddy. At the top, the wind smells of heath and the ancient iron of the mining spoil heaps.
The ridge has three peaks: Biderdi (871 m), the central peak (999 m), and Galarraga (901 m). From the summit, you can see Bilbao, Pagasarri, and Sollube mountain.
Wear boots or trainers with good tread, a windbreaker, and a map or track: the fog rolls in quickly. If you want more, link up with Pagasarri for a demanding traverse; if the weather changes, shorten the return from a col.
La Arboleda is 25–35 min from Bilbao.
Plentzia – Gorliz: beach stroll and tranquil coast
Fine sand slips between your fingers while the murmur of the estuary sets the pace.
If you add the lighthouse and the cliffs, the circular route is 6 km with low difficulty.
To eat, take sandwiches to the shade of the pines by the beach or sit in a tavern with a menu of the day just a stone's throw away. The starting point is the Astondo beach car park, next to the Gorliz Hospital, which you can reach by car or by public transport from Bilbao.
Mount Oiz: summit and panoramas of the Bizkaia interior
Mount Oiz (1,026 m) is a summit in the interior of Bizkaia, with grassy hills and wind turbines on the ridge. Its wind farm has made it a symbol of Bizkaia.
The classic ascent starts from the Balcón de Bizkaia and follows a clear route via track and path up to the summit cross. The round trip totals 9–12 km, with 419 m of elevation gain and a duration of 3–4 h. The difficulty is moderate due to the elevation gain and the frequent wind at altitude.
At the summit, there is a monument to the Virgin and panoramic views of Urkiola, Anboto and the Bizkaia mountain ranges; on clear days, you can see the Cantabrian Sea to the north. In mythology, Oiz is the home of the goddess Mari alongside Mount Anboto, and its slopes contain dolmens and burial mounds from ancient pastoral activity. At the summit, the air bites your face and the slopes smell of grass freshly combed by the wind.
Avoid foggy days and strong gusts and take a thermal layer even in summer. From towns such as Munitibar or Ziortza-Bolibar, you can climb via local roads to the Balcón de Bizkaia, which has limited parking on weekends. Public transport is limited, so it is advisable to plan a carpool or a rural taxi for your return.
What to see and do on the route: flysch, viewpoints, beaches and heritage
In the flysch, the hard rocks resist and form ridges; the soft ones erode, leaving parallel grooves that look like ploughs in the stone. The landscape reads like a record of time, with alternating layers of limestone and marl, folds and faults visible from the high paths.
The polished areas of the flysch are slippery: use grippy footwear and do not access them as the tide is rising. For photography, the natural viewpoints on the coast work well with long exposure at sunset, and the beaches allow you to swim at the end of your hike.
Sopela, Gorliz and Laida have showers, lifeguards in summer and wide sandy areas. In coves below cliffs such as Barrika and Meñakoz, keep in mind that they are difficult to access by land and that the rocks increase their danger. The Barrika coastal path is of low difficulty, connects with Gorliz beach and has views of Cabo Villano; its surroundings are of high geological value, with transparent waters at Muriola beach.
In Astondo, there are petrified dunes that are 6,000 years old. Gaztelugatxe can be seen from the high viewpoints and Cabo Matxitxako: bring a lightweight tripod, a polarising filter and a waterproof jacket for your equipment if the sea spray intensifies.
Hermitages such as San Telmo (Zumaia) or San Juan (Gaztelugatxe) and bridges over the estuary (Plentzia) dot the routes. In Urdaibai, birds can be observed during the spring and autumn migrations, and in spring and summer many nest in the Atlantic countryside and the reed beds.
You can complete the day with surfing in Sopela and Mundaka (with previous experience recommended in Mundaka), paddleboarding in Plentzia and Gorliz with calm seas, or kayaking through the Urdaibai estuary with the tide rising to take advantage of the current. As you reach the top of a lighthouse, the smell of iodine and pine mixes while the horizon turns orange.
Plan with plenty of time, ask locals and respect the signs: coastal communities live here all year round.
Itineraries for 1–3 days: maps, times and combinations
Bilbao allows you to put together a one-day getaway without a car and a weekend with a car along the coast. Before setting off, download official maps and apps with reliable tracks and topography: OpenStreetMap and the cartography from the Diputación Foral de Bizkaia work well. Mark waypoints for car parks, train and bus stops, and safe alternatives if the weather worsens.
A day without a car, looking out at the sea. Take the Metro Bilbao L1 to Sopela early and return to Bilbao on the L1. In the afternoon, walk through Plentzia to Gorliz and have a swim.
Gaztelugatxe has a steep path ascent with 241 steps; the full visit lasts between 1.5 and 2.5 hours. In high season, you must book for the peak hours. Stay overnight in Mundaka or Bermeo to reduce travel times.
The driving times are these:
-
Bilbao–Gaztelugatxe: 45–60 min.
-
Oiz–Bilbao: 44 min.
Buy your tickets in advance and check for works on Euskotren; if you combine car and train, use park and ride facilities.
Depending on your level. If you are starting out, Plentzia–Gorliz, Artxanda and short sections of Sopela.
Keep the Metro Bilbao, Euskotren and Bizkaibus timetable apps and the Puertos del Estado tide tables at hand. Leave plenty of time: the weather can take a turn and rushing is a bad companion.
Frequently asked questions
What is the best time to go hiking near Bilbao?
Spring (April–June) and autumn (September–October) are the best times: mild temperatures, fewer people and good light for photography. In summer you can also walk and combine the route with beaches and coastal walks, but get up early and avoid the midday hours on hot days.
Winter brings clear days and intense greens, with more rain: bring a waterproof jacket and an urban plan B. On the coast and the flysch, the north wind and rain can suddenly make the route tougher, so check AEMET or Euskalmet on the same day.
For the flysch, check the tide tables and the coefficient: the greater the range, the more water covers the platform. With a strong swell or high tide, stay on high paths and viewpoints. After the rain, the walkways and rocks can be slippery; on that day, the smell of seaweed will accompany you on the path.
Which route is most suitable for beginners?
To start, two safe bets: Plentzia–Gorliz and Monte Artxanda.
Plentzia–Gorliz follows the promenade that connects Plentzia and Gorliz, with 4–6 km of promenade and sand and the possibility of extending to the lighthouse. It has public transport available, so you can go and return without a car.
Artxanda adds urban views with low difficulty and access via funicular or marked paths. Walking while listening to the seagulls over the Plentzia bay will remind you that starting slowly is also a way to enjoy.
Three tips before setting off:
- Wear footwear with grippy soles even if the profile is easy: wet wood and rock are slippery.
- Carry water and a snack even on short walks; the salt spray makes you thirsty.
- Check the return transport schedules so you don't have to rush.
Can you do the flysch route without technical experience?
Yes. From the viewpoints and the prepared walkways, the flysch route is suitable for everyone and the geological reading can be appreciated just the same.
Going down to the rocky platform is another matter: it requires low tide and calm seas. The striated rock is slippery and some exits via the beach become blocked when the tide rises. The sound of the waves between the stone ridges is deceptive: when the tide rises, it rises for real.
Check the tide tables and plan to enter as the tide is going out, leaving a margin to get out. If you have doubts, opt for the guided tours of the geopark or stay on the high marked paths.
Avoid smooth footwear and bring poles: they help on wet rock.
What public transport is available for these routes?
Towards the flysch, Euskotren goes to Donostia with stops in Zumaia and Deba; check schedules and possible works before setting off.
Plan your return: save the Metro Bilbao, Euskotren and Bizkaibus websites on your mobile and note down the last departure of the day. Hearing the screech of the train arriving at the platform as evening falls feels like well-earned rest.
