Main image

Gaztelugatxe is a small rocky islet on the Basque coast linked to the mainland by a stone bridge and a long stepped path, located in the Basque Country of northern Spain. It is crowned by a small chapel dedicated to Saint John (San Juan) and is a prominent coastal landmark.

The islet and chapel are popular for the distinctive walk to the hermitage, coastal views and the rocky coastline; the route culminates at the chapel after the series of steps and the short bridge. The site is known for its dramatic setting rather than extensive built fabric.

The hermitage dates back to the medieval period and has been rebuilt and repaired on multiple occasions; it has served as a small pilgrimage site and local devotional place. The causeway and steps are the principal historic access and have been maintained for visitors.

Gaztelugatxe sits on the Bay of Biscay coast in the Basque Country, near towns on the coastal strip and within driving distance of Bilbao and other coastal communities. The islet projects from a rugged coastline of cliffs and surf.

  • 241 steps: The walk from the mainland to the hermitage involves climbing a long stone staircase of 241 steps and crossing a narrow stone bridge to the islet.

What to See #

  • Hermitage (San Juan): Hermitage of San Juan de Gaztelugatxe - Small medieval chapel on the islet, historically rebuilt several times and reached by a stone bridge and long stepped path.
  • Staircase and bridge: The stone stairway and bridge - A man-built causeway and staircase connecting the islet to the mainland, commonly reported to include 241 steps and forming the main visitor route.

How to Get to Gaztelugatxe #

Tips for Visiting Gaztelugatxe #

  • Walk the stone bridge's 241 steps slowly - the climb is scenic and often windy; there are railings at intervals but some sections are exposed.
  • Arrive early to avoid bus tours and to catch morning light striking the hermitage's red-roofed islet.
  • The site can be combined with nearby San Juan de Gaztelugatxe approaches and the fishing village of Bakio for a full coastal day.
