Cueva de los Cerebros is an advanced cave dive off Playa San Juan.
Boat access from Playa San Juan is best handled by a local cave-capable operator.
Cueva de los Cerebros is a boat-access cave dive off Playa San Juan, with volcanic tubes, small arches, and a shadowed interior that make the route feel very different from an open reef. The cave is known for brain-shaped sponges, and if conditions are calm you may reach a fresh-air pocket at the end. It is an advanced dive that rewards a light, steady pace and a torch. Expect moray eels, conger eels, shrimps, crabs, nudibranchs, wrasse, bream, and rays.
