What it is like

Characteristics published by official sources

Playa Os Castros - Illas is a 500-metre fine-sand beach with the usual conditions of an open beach. Its length gives it a prominent presence on the Ribadeo coast, while the sandy composition defines a continuous surface with a fine texture. Its public name retains two references, Castros and Illas, which form part of the recorded identity of the place. The listing records no details about relief, the immediate surroundings, access or services, so those aspects are not included in the description.
