Baia, in the Phlegrean Fields, in the province of Naples, at the time of the ancient Romans became a thriving health and holiday location, near the important commercial port of Portus Julius and the base of the military fleet of Capo Miseno. In this area the phenomenon of “bradisismo” , due to the volcanic action of the territory, caused the sinking of part of the important ruins. Imperial baths, precious mosaics, sinuous statues and marble floors have been found underwater.

To protect all this, in 2002 the Archaeological Marine Park of Baia was created with an incomparable historical and cultural value. There are 5 underwater sites, ranging from 5 to a maximum of 13 meters of depth, therefore suitable both for SNORKELING, for SCUBA DIVING (scuba diving for certified divers) and, for TRY SCUBA diving for beginners.
