This dive site, Brains Cave, is a fascinating underwater cavern located just a 10-minute boat ride from Playa San Juan. The cavern features two distinct halls, with the left hall distinguished by a natural hole in its ceiling that beautifully illuminates the interior. Divers navigate through these shallow halls, experiencing the unique geological formations and interplay of light and shadow. There's no specific history or story provided for the site, its name likely deriving from its most famous inhabitant.
The main highlight of Brains Cave is the rare brain-looking sponge, Corallistes nolitangere, which is exclusively found in caves between Portugal and Cape Verde that have freshwater access. Beyond this unique macro life, divers can expect to encounter various common reef fish species typical of the Canary Islands, inhabiting the cavern walls and surrounding reef.
The best time to visit Brains Cave is generally year-round, as the Canary Islands offer stable diving conditions. Divers should be comfortable with cavern environments, although the natural light makes it suitable for many. It is also an excellent site for freedivers and snorkelers who wish to explore the well-lit entrance and shallower parts of the cavern, offering a memorable experience for all.
