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.

small viewing summit at Playa des Illas. only accessible at low tide (on dry feet) it is not as crowded here as the completely overcrowded As Catedrais beach, but almost as Instagrammable warning: as of 08/24, the Portuguese man o' war is hanging around here, which can be very painful (at least) if touched

The most spectacular features of the natural monuments, especially the arches and caves of Beach of the Cathedrals, are only accessible at low tide. It is crucial to check the tide schedules before your visit to ensure you can fully experience the beach floor. During high tide, the dramatic scenery can still be admired from the clifftop paths.
