It is a hydrological basin in its natural state dug into the stone of a valley. In Cavascura it is possible to relive the very ancient times because it still retains its caves, its small waterfall, its boiling springs that continue to come down from the mountain at a very high temperature.It is located about 300 meters from the Maronti beach and is accessed by following a stream of hot water that opens onto a small bed between the tuffaceous walls of the hill.
