Las Catedrales beach is a natural monument of extraordinary dimensions. All you have to do is wait for low tide, take off your shoes, start walking... and you'll feel like you're in heaven. There's nothing like enjoying the view of the 30-metre-high flying buttresses, discovering unusual perspectives of arches within other arches. Or simply, letting yourself be carried away by the sandy corridors between slate walls, like in an imposing and whimsical central nave.

A ticket is required for access from July to October, which is available here: https://ascatedrais.xunta.gal/monatr/inicio?lang=en is to get. The tide times are also noted here.
