The Mario Wreck is probably one of the most snorkeleable wrecks along the Corsican coast. Located about 150 m from a beach and at a moderate depth (26 to 30 ft/8 to 9 m), it is easily accessible and can be enjoyed from the surface of the sea. Covered with algae and sponges, the wreck attracts around it many fish such as damselfish, combers, saddled seabreams and red mullets.

How to get to the Mario Wreck snorkeling spot?

The Mario Wreck is located in Pietrosella, a coastal village located about 13 km south of Porticcio and 24 km south of Ajaccio. The wreck is about 150 m in front of Stagnola Beach (Plage de Stagnola).

If you come by car, the easiest way is to park at the Isolella car park, about 300 m on foot from the beach, but there are also a few parking spaces closer. Once on Stagnola Beach, walk up towards the east (on your right when you are facing the sea) until you encounter a stone wall.

Mario Wreck snorkeling exploration tips

To reach the wreck, snorkel perpendicular to the beach for about 150 meters. You should soon see the shape of the wreck on the seabed.

The Mario Wreck, a tug almost 18 meters long, is placed on the sand, 26 to 30 ft/8 to 9 m deep. Sunk in 1993, the wreck is in very good condition and offers a very beautiful underwater landscape.

If you skindive, you can get closer to the structure and observe the underwater life that calls the wreck home. The Mario has been covered over time by different types of algae and by sponges from Dictyonella genus, forming an oasis of life in the middle of the sandy beds.

Structure of the Wreck of the Mario
The wreck offer lots of hiding places.

The Mario supports shoals of saddled seabreams and damselfish, as well as many painted combers which like to shelter in the hiding places offered by the wreck. Red mullets are common around the wreck, busy feeding on the sand.
