Just north of Punta Libeccio, at about 100 m from the coast, a site known as the “Relitto dei Cannoni” (the “Wreckage of Cannons’’) can be found at a depth of 15 m. The gently sloping seabed, which is characterised by naturally split rocks alternating with clearings of sand and gravel, contains traces of an ancient shipwreck: eight cannons of uniform size and characteristics, six of which are lying in disarray along a vaguely rectilinear axis, while the other two are offset by about 20 m to the west. The total distance between the farthest cannons is about 30 m. 

Cala Gadir offers itineraries that are suitable for divers with open water licenses, as well as more advanced divers. The dive begins near the first slipway, which reaches a depth of 6 m at the entrance corridor marked by yellow and white buoys. Heading about 20 m to the north, you will come to a rocky ridge.
