PLAYA DE AS CATEDRAIS 43°33.240′ N · 7°9.480′ W 1 km SCHEMATIC
Schematic shoreline — real coastline pending

Gothic arches of slate that only exist at low tide, with entry rationed by a permit system.

Praia das Catedrais — the Beach of the Cathedrals — is on the Galician coast near Ribadeo, in north-western Spain. Its official name is Praia de Augas Santas, and the popular one comes from the arches and buttresses the Atlantic has cut into the slate cliffs, which resemble a ruined nave.

It only exists twice a day. At high tide the beach is under water and the arches are inaccessible; at low tide a wide platform of sand opens up and the formations can be walked among. Everything about a visit depends on the tide table, and arriving at the wrong hour means seeing nothing.

Visitor pressure forced a rationing system. Since 2015 access during the summer months and at Easter requires a free permit booked online in advance, with a daily cap in the low thousands; without it the beach was taking numbers that damaged the formations and made the narrow access unsafe. The permit is free, it is checked, and it runs out. Galicia's coast holds the Rías Altas and Baixas, drowned river valleys that give the region its shape and its shellfish industry.

The rock is slate and schist, layered and fractured, and it is eroding — arches collapse, and sections are fenced after falls. The water is cold Atlantic and swimming is not the point; walking among the formations at low water is. The Rías Altas either side hold dozens of beaches with no permit system at all, and Praia de Rodas in the Cíes Islands further south is the Galician beach that appears on lists.

Two hours of arches and then the sea takes them back. Book the permit, read the tide table, and understand that arriving at high water means seeing nothing at all — a fact the photographs cannot convey and that catches out a great many visitors each summer.

Questions

Do you need a permit?

Yes, during the summer months and at Easter. It is free, booked online in advance, capped daily, and checked at the entrance.

When can you see the arches?

At low tide only. At high water the beach is submerged and there is nothing to see. Check the tide table before travelling.

Why is it called Cathedrals?

The Atlantic has cut arches and buttresses into the slate cliffs that resemble the nave of a ruined church. The official name is Praia de Augas Santas.

Is Praia das Catedrais safe?

The rock erodes and arches have collapsed; sections are fenced after falls. Observe barriers and do not be caught by the returning tide.

Is Praia das Catedrais good for swimming?

It is not really a swimming beach — cold Atlantic water, and the sand exists only at low tide. Walking among the formations is the activity.
