Gulpiyuri is one of the most unusual beaches in the world: a small enclosed beach, about 40 metres wide, that sits entirely inland in a grassy meadow with no visible connection to the sea. When the tide rises, water fills the bowl through an underground cave system in the limestone, creating a miniature beach surrounded by green fields and hedgerows. At low tide the sand lies exposed, the water retreats, and it looks like an inland pond. At high tide, it becomes a proper swimming beach, albeit a tiny one.
The beach is about 12 km east of Llanes near the village of Naves. A signed path from the road leads down through fields to the beach — the walk takes about 10 minutes. Do not come at low tide expecting to swim; it is the incoming tide that makes Gulpiyuri magical. Check the tide tables before visiting. There is no infrastructure at all — no toilets, no shade, no facilities. It is a Natural Monument and strictly protected, so do not damage the cliffs or vegetation.
