One of this dive’s main peculiarities is the vertical extent of the volcano’s wall. It ranges from 10 to 15 m in depth next to the rocks above the surface, to abysmal depths below. The area is characterised by awe- inspiring lava rock and black sand, with yellow nuances caused by the sulphur residues. You will see small columns of bubbles escaping through the cracks in the seabed and racing towards the surface. The dive takes place along the wall, first proceeding in one direction, and then returning to a lower depth in the other direction. The route follows the channel of sand, and arrives at the edge of the shoal that marks the boundary between the coast and the cliffs on shore. One of the small caves along the coast continues into the rock for a few metres and ends at a small underground lake. Turning right at the exit from the tunnel, you will find a small indentation where the sand has turned yellow due to the sulphur released by the minute gas emissions.

IMPORTANT. Due to the gas emissions and veins of hot water, the water of the bay that houses the Sirenetta rock outcropping and the on-shore caves is turbid for the first few metres.
