The Cala Martino dive begins on the rocky outcropping that extends in a southerly direction, and reaches the bedrock at a depth of 12 metres, with a uniform cover of sea grass. From the edge of the rocky strip, it descends rapidly to 23 m in depth, where the sea floor consists of a landslide of boulders and sand. The dive continues over the landslide in a south-easterly direction for about 40 metres, maintaining a maximum dive depth of 25 m, even if the seabed continues to slope downward. At the base of the rock wall, and between the boulders from a landslide, numerous crevices and small caves with sandy bottoms can be observed. Re-ascending along the same pathway in reverse, at the depth of 15 m you will encounter a wide cave with the sandy bottom. On the left hand side at the end of the cave, there is a siphon about 1.5 m wide that offers an easy exit route, after which you will find yourself on the rocky strip.
