Gastelugache (its full name is San Juan de Gastelugache, San Juan de Gaztelugatxe) is a tiny island in northern Spain, off the coast of the Bay of Biscay.
The island is connected to the mainland by a narrow path and to get to it, you will have to overcome not only two arched bridges, but also 230 steps, of course, provided that the purpose of your hike is a hermitage, which has already gone the eleventh century.
