Off Punta del Papa, just outside zone A, from the detrital bottom of about 45 meters there is a sequence of limestone reliefs that continue the profile of the tip underwater. The bank is divided in two by a sand channel (Papa 1 and Papa 2) and the upper part of the first relief is 15 m, the second one at 24 m. Each of the two parts is served by a mooring buoy.
To the west of the promontory, the cave of Nereo has an extension of about 350 meters and in some places the height of the vault exceeds 10 m. The main entrances are three: one at 20 m depth, one at 18, the most spectacular also called Archi di Nereo and one at 32. Only the areas near the entrances receive light from the outside. The internal tunnels are completely dark and you need to use a cave diving organization.
The wreckage is that of a large merchant ship large enough armed for defensive purposes, sunk by a famous English submarine which, in 1943, was the origin of numerous shipwrecks. It is located in two sections at a distance of about 1.5 km: the deepest arch at -45, the stern and the central part between -34 and -42, this will be the goal of the dive. This part of the wreck is about fifty meters long, the general state of conservation is quite good and the ship still seems to be underway, they are possible with great caution and the necessary preparation for the penetrations into the hold, in the engine room and on the bridge.
Also called Secca Washington, it consists of a vast rocky relief whose hood reaches up to 6 meters from the surface.
It consists of huge granite blocks eroded in an aerial environment, surrounded by rocks, landslides, tafoni and depressions which, in the deepest points, slightly exceed 25 m. The many possible and varied routes start from the four buoys anchored on the bottom which reach about 4 m from the surface, clearly identifiable in unfavorable weather conditions.
