Description: The Basque coast is rough in this area. The sea ceaselessly erodes the rocky coast creating tunnels, arches and caves. The island of Gaztelugatxe is in the center of this section of coast next to the small Aketx island, a sanctuary for marine birds. Next to the hermitage there is a small shelter with sea views that is used for picnicking and for refuge from the wind. The hermitage is accessed by a narrow path, crossing the solid stone bridge, and going up 231 steps (other sources cite the number as 229 or 237). According to legend, after the slightly strenuous climb to the top of the crag one should ring the bell three times and make a wish. HBO filmed scenes for season 7 of its fantasy series Game of Thrones at the islet. Gaztelugatxe stood in for Dragonstone, with a digitally created castle on top of the islet.
