The GrottaTrombetta has the entrance shaped like the musical Instrument. The muddy bottom starts from - 35 mt at the beginning arriving at -12 mt Inside. We enter close to the celling (-20 mt) so we keep far from the mud. The mediterranean feather star Antedon medíterronea, the spirograph Sabella spallanzani, the yellow clathrina sponge Clathroa clathrus and various crustaceans live here. At the end of the main way we reach the base of a narrow  chimney ending with an air bubble. Only three divers can surface. On the way there are beautiful cave formations. We reserve this part of the cave for very experienced and equipped divers because claustrophobia and equalization problems haven't an easy solution. Close to the muddy bottom starts another extremely narrow tunnel I explored many years ago with my friend Marco Oliverio. We called It the Crypt. It's very dangerous because the return is always with zero visibility. Before going out, the blue in sight, let's stop at the striped cave prawns Plesioniko narval niche. Fifty metres separate this cave from the Stairway cave. Its worth covering the distance at a depth o` 20-25 metres. Look at the blue, some groupers moves there. This is the octopuses road because the number of these cephalopods was elevate. I say was because Idiot divers fish them while venting eggs. At minus twelve metres the flat and rocky bottom of the Stairway cave opens We visit only the atrium because the cave is part of the White Point Complex, reserved at very experienced and equipped cave divers. The walls are orange for the presence of the star coral Astroides .Easy to meet the cave spider crab. After ten metres looking at the top we nave a fine view of surface between rocky walls in front of us starts a small tunnel giving access to a very dangerous pit. Let's stop here.
