Playa de Cobijero, Inland beach in Llanes, Spain

Playa de Cobijero, also called Playa de Las Acacias, is an inland beach in a limestone depression in Buelna, Llanes. It is cut off from the coast and linked to the sea by a crack tens of metres long, so tides and waves reach it from below. To the north, an eroded rock outcrop forms the stone arch known as Puente Caballo and a blowhole; to the south, a small stream drains through a channel cut in the limestone.

The Complejo de Cobijeru, covering 8.73 hectares around the beach, was declared a Natural Monument by Decree 140/2001 on 5 December 2001 and included in the Paisaje Protegido de la Costa Oriental de Asturias. The complex comprises the Cobijeru depression, the El Molín depression with its old tidal mill, the karstic Cobijeru cave and the northern cliff.

The beach is also called Playa de Las Acacias. It lies in the Cobijeru Complex, declared a Natural Monument by Decree 140/2001 on 5 December 2001 and included in the Protected Landscape of the Eastern Coast of Asturias. Nearby stands an old tidal mill by the muddy, vegetated depression of El Molín.

The beach lies in a limestone depression northeast of Buelna, inside the 8.73-hectare Cobijeru complex, and is cut off from the open coast; the sea enters through a fissure tens of metres long, so the sand is covered at high tide. A small stream drains the depression on the south side and can swell after rain. The neighbouring El Molín depression has a muddy, vegetated floor.

What sets this cove apart from nearly any other beach is that there is no conventional shoreline where waves roll in: the sea enters entirely through cracks and fissures in the surrounding rock. Watching the water rise and fill the pool from below gives the place a quality that is hard to find elsewhere on the coast.
