Playa de Borizu, Sandy beach in Celorio, Llanes, Spain

Playa de Borizu is a shell-shaped beach of fine white sand between Barro and Celorio, in the municipality of Llanes, measuring 400 metres long and about 65 metres wide on average. It faces the small island of Arnielles or Borizu, whose western part is called Las Cabreras, and at low tide a strip of sand joins beach and island. Its vegetation places it within the Paisaje Protegido de la Costa Oriental de Asturias.

Borizu lies in the municipality of Llanes, between the villages of Barro and Celorio, on the Costa Verde of eastern Asturias. Its vegetation led to its inclusion in the Paisaje Protegido de la Costa Oriental de Asturias, a protected landscape designated under the Principality of Asturias and listed by Spain's Ministry of Agriculture, Food and Environment.

The beach lies between the villages of Barro and Celorio, and the island facing it is called Amielles or Borizu, with its western part known as Les Cabreres. The Asturian name Borizu and the Spanish Borizo both appear on local signs, and the sandbar linking beach and island shifts with the tide.

The beach is easily accessible with plenty of parking nearby and good basic facilities for visitors. The best time for swimming is from June to September, when a rescue service is on duty.

The island facing the beach carries two names: Arnielles or Borizu, and its western end is called Las Cabreras. At low tide a strip of sand links the beach to it, so bathers walk across the same channel the sea covers at high water.
