Advanced volcanic cave dive off south Tenerife
Palma Mar Cave is a demanding boat dive off south Tenerife with a volcanic plateau, a deeper cave entrance, and a route shaped by lava walls rather than open reef. The site rewards steady buoyancy and a calm plan, with the main draw being the cave mouth, the surrounding rock, and the fish life that gathers around the structure rather than any long penetration.
