Advanced Ustica cave dive with shrimp, lobsters, and a huge chamber.
Advanced Ustica cave dive with shrimp, lobsters, and a huge chamber.
The site is normally arranged through local Ustica dive centers that handle cave-qualified groups.
Grotta dei Gamberi is Ustica's classic overhead cave dive off Punta Galera, run as an advanced boat site for divers with the right qualification. The route drops through a wall into a huge chamber, then threads the cave system while shrimps, lobsters, conger eels, and other cave life crowd the darker sections. It is a planning-heavy dive where lights, buoyancy, and a local briefing matter more than easy reef sightseeing.
