Portofino's dive sites span a wide range of formats: shallow beginner reefs, multi-environment walls, technical wrecks, caves, and open-water pinnacles. The wreck catalogue alone runs from accessible intermediate dives like the Relitto Sarchiapone to deep technical targets such as the KT Eros UJ-2216. Nudibranch diversity is a defining trait, with species including the Mediterranean Violet Aeolid, Cratena Slug, and Giant Doris observed across most sites. The Great Barracuda and Mediterranean Moray are encountered with high regularity.

The peak diving window runs from late spring through autumn, when conditions are most inviting and site variety is fully accessible. Some exposed sites such as Faro di Portofino and Secca Isuela carry moderate currents, so conditions vary meaningfully between sheltered and open-water locations.

Yes, several sites are well suited to beginners. Sant'Anna and Santa Reef both offer shallow shore entries, while Scoglio Nave and Isola Gallinara are accessible beginner boat dives. Intermediate and advanced divers have an equally wide range of options, from walls and caves to deep technical wrecks, so groups of mixed experience levels are well accommodated.
The large majority of sites require boat access, and operators such as Haven Diving Center srl, Dimensione Diving, Abissi, and Seasub provide guided boat diving across the area. Shore entry is available at a small number of sites, including Santa Reef and Sant'Anna in Santa Margherita Ligure, which are useful for training or introductory dives.
Wrecks and reef walls are the two defining site types. Wreck dives range from intermediate-level targets like the San Guglielmo to deep technical dives on the KT Eros UJ-2216. Wall diving is prominent at sites including Faro di Portofino, Il Bigo, and Grotta dei Gamberi, the latter also featuring cave and canyon topography. Pinnacles such as Secca Isuela add further variety for advanced divers.
