Sea caves and lava arches are where the Canaries stop being just sand and water and turn architectural. On these volcanic islands the Atlantic has hollowed the coast into caves, channels and broken rock — the literal cave that gives Cueva de Lobos on Fuerteventura its name, the volcanic rock formations that shelter Playa de los Roques on Tenerife, and the rock formations that ring the calm pools of Los Charcones on Lanzarote. This guide includes only beaches whose own descriptions record those features, so it stays tighter than a general scenery list.
Many of these places double as cliff beaches or natural rock-pool spots, and a cave is not always swimmable or safe to enter — swell, boat wake and wind can change that hour to hour, so treat the feature as scenery and a planning signal, not a promise. For neighbouring themes such as cliff-backed and natural-pool beaches, browse the guides index; to compare on other criteria see the best Canary beaches, or place each cove on the map.
