Island and Monastery in Bilbao

Perched dramatically off the Biscay coast, San Juan de Gaztelugatxe is one of northern Spain's most unforgettable sights. This tiny rocky isle, connected to the mainland by a winding stone bridge with 241 steps, offers sweeping ocean views, centuries of legend, and a sense of wild isolation that's deeply evocative. The hermitage crowning the island dates back to the 10th century and is dedicated to Saint John the Baptist, who is said to have once set foot here. With every step you climb, the Atlantic wind, the sound of crashing waves, and the scent of salt in the air create an experience that feels almost timeless.

Located about 35 kilometres east of Bilbao, this dramatic setting has long inspired locals and travellers alike. In recent years, it gained global fame as Dragonstone in season seven of Game of Thrones, but even without the cinematic connection, its beauty is undeniable. Whether for its medieval mystique, spiritual calm, or cinematic appeal, San Juan de Gaztelugatxe is one of the best trips to go on from Bilbao and a must-see for anyone exploring the Basque coast.

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.
