Giannutri's diving is defined by dramatic vertical terrain. Walls and drop-offs plunge to serious depths at sites like Punta San Francesco and Secca di Mezzo Canale, while caves at Grotta Maurizio Sarra and Argentarola Caves reward technical divers. Gentler reefs at Gli Archetti and Cala dei Santi suit beginners. The Anna Bianca wreck adds variety. Common Octopus, Mediterranean Moray, Gorgon's Head and a rich nudibranch fauna appear consistently across the sites.
