San Juan de Gaztelugatxe, Bilbao

Island and Monastery near Bilbao

CC BY-SA 4.0 / Clementp.fr

San Juan de Gaztelugatxe is a small rocky islet near Bilbao, Spain, reached by a stone bridge and a steep climb of 241 steps. The site is best known for its hermitage at the top and its exposed position above the Bay of Biscay, where waves, wind, and cliff edges shape the experience as much as the chapel itself.

Visitors come here for the coastal walk and the setting, not for a long list of sights. The approach can take effort, especially in wet or windy weather, but it rewards you with wide views and a clear sense of place. It suits travellers who enjoy outdoor visits, sea landscapes, and a short stop that feels active rather than polished. Those who prefer easy access or step-free sightseeing may want to stay at the viewpoints instead of doing the full climb.

History and Significance

San Juan de Gaztelugatxe’s history stretches back over a thousand years. The hermitage atop the island was first built in the 10th century by the Knights Templar and has been rebuilt several times after suffering fires and pirate attacks. Its name in Basque - “Gaztelu-aitz” meaning “castle rock” or “Gaztelu-gatxe” meaning “inaccessible castle” - perfectly describes its striking form. For centuries, it has been a site of pilgrimage, with worshippers climbing the steps to ring the small bell three times and make a wish. The view from the top, where the land meets the endless Atlantic, offers a glimpse into the Basque people’s enduring relationship with both nature and faith.

Things to See and Do

The main attraction at San Juan de Gaztelugatxe is the climb itself - 241 uneven stone steps that zigzag dramatically up to the hermitage. Along the way, small rest points and viewpoints provide stunning photo opportunities of the coastline and sea arches below. Once at the top, visitors can explore the small chapel dedicated to Saint John, light a candle, and ring the bell to bring good luck. The surrounding cliffs and waves crashing below make this one of the most photogenic spots in the Basque Country. Back on the mainland, a scenic coastal trail connects to viewpoints overlooking the island, offering perspectives equally beautiful from a distance.

How to Get to San Juan de Gaztelugatxe

San Juan de Gaztelugatxe is located near the town of Bermeo, about a 40-minute drive from Bilbao. Visitors arriving by car can follow the BI-631 road through Mungia and Bakio, where parking areas are available near the viewing points. If you are looking to rent a car in Spain I recommend having a look at Discover Cars, first, as they compare prices and review multiple car rental agencies for you. From there, a 15- to 20-minute walk leads down to the start of the bridge. Public buses also run from Bilbao to Bakio and Bermeo, though schedules can be limited outside peak season. Guided tours from Bilbao are a convenient option, often including stops at coastal villages like Bermeo or Mundaka. The site can be quite busy in summer, so early morning or late afternoon visits are recommended for a quieter experience.

San Juan de Gaztelugatxe sits on a rocky promontory reached by a winding cliffside trail offering dramatic coastal panoramas and a small chapel; visitors say the climb down and up is steep with unpaved, potentially slippery sections so sturdy boots and preparation are advised, and many find the effort—rain or shine—rewards with unforgettable views and a powerful atmosphere even if the chapel isn't always open.

"Just beautiful. Note the hike is not your typical stroll, it was very steep getting down to the actual crossing and sections were unpaved so if it'srained it will be slick and muddy. Totally worth it though, and a lovely way to see the coastline...."

"At first, the drive down didn’t convince me it was worth it—but this spot absolutely deserves a place on your list. The setting is incredible, almostsurreal, making even the most dramatic Game of Thrones scenes feel tame in comparison. We caught it right at sunset, and the views were unforgettable. Fair warning: the hill is steeper than it looks, so be ready to give your calves a workout...."

"Gaztelugatxe was by far the most impressive experience of my trip through the Basque Country. Come rain or shine, the sea crashing against the rocks,the path across the bridge and up the stairs to the chapel. One of the few tourist hotspots that you can still enjoy to some extent. The small effort required to walk to the hermitage itself enhances the experience. The registration requirement and the associated access restrictions add to this. Unfortunately the chapel is not permanently open. Please don't let the weather dictate your trip here! Even in rain, wind and storm (perhaps especially then) this place exudes a unique aura...."

"A bit overrated tbh - careful on the way down - long and steep, can be slippery when the fog comes down. U need to walk all the way down to sea leveland then all the way up to the church - plus the same on the way back.. it‘s a nice place to visit but not a „must see or do“..."
