La Spezia's dive and snorkel sites centre on reefs, caves and pinnacles spread across both shore and boat entries. Most sites suit beginners, with shallower reefs giving way to deeper slopes and walls at spots like Punta Persico and Punta dell'Isola Palmaria. Caves at Grotta Byron, Cala Grande and Grotta del Tinetto add variety. The Common Octopus and European Common Cuttlefish are the area's standout encounters, alongside a reliable cast of bream, wrasse and nudibranchs across almost every site.

Autumn remains comfortable and is worth considering for quieter dives, while winter diving is possible but demands more thermal protection.
