Villasimius offers a varied dive portfolio built around reefs, pinnacles and a remarkable collection of Second World War wrecks. Beginner-friendly shallow reefs such as Sassone and Punta Molentis sit alongside deeper advanced dives on the Romagna, Lt221 and Isonzo. The signature species are the Common Octopus, European Common Cuttlefish and Dusky Grouper, while Turkish Wrasse, European Parrotfish and Painted Comber appear across virtually every site. Almost all diving is boat access, served by a strong local operator community.

Villasimius has several distinct wartime wrecks spread across a range of depths. The Entella, a troop transport, sits shallow enough for intermediate divers, while the Romagna tanker places its deck at a depth accessible to advanced divers. The Lt221 tugboat lies on its side and split in two at greater depth, and the Isonzo, an armed cargo ship also resting on its side, reaches the deepest of the group. Each wreck has its own character in terms of structure and penetration potential.
The great majority of dive sites in Villasimius require a boat, and the area has a substantial number of local operators including Tamatete, Oceanblue Diving, Seaworld Diving Center and Archeo Diving among others.
