Playón de Bayas (Castrillón)
The longest beach in Asturias at nearly 3 km, on the Castrillón coast near Salinas. The left-hand half is a marked, year-round dog zone of around 250 m, separated from the human side and equipped with showers and fountains for dogs and people. This is the closest fully reliable dog beach to Oviedo and the best bet for a summer swim with your dog when the urban beaches are closed. Verify the current dog-zone limits with Castrillón turismo before going.
Normas: On lead outside the marked dog zone. Bag required. PPP breeds always leashed & muzzled.
