The cave of Palm mar is one of the main dives in the south of Tenerife. Once deep down the dive is articulated between large rocky boulders and sand where it is easy to meet turtles and rays that reside here. At a depth of 30 mts is the entrance to the cave which is thought to extend for about 60 mts with different ramifications. During the dive it is recommended not to enter the cave but to stay close to its entrance, which is full of marine life. Outside the cave there is a cross, in memory of the four people who lost their lives during the exploration of the cave.
