This threatening right has only recently started to be surfed, having gained notoriety in recent years due to its spectacularity. It is extremely radical, tubular and risky. With an angle of the coast still facing south, it breaks over a reef plate that does not connect with land, located at very little depth. The suction of water from the bottom of the wave towards its top is so intense that this part below the water line – hence the name -, with the tube that forms there to become progressively more hollow, wide and flat as the wave approaches the end. The Cave is only intended for experienced and technically advanced surfers, and even these are advisable to use protections.
