Catania's dive sites are shaped by volcanic geology, with lava rock walls, pinnacles, arches and caves forming the backbone of nearly every dive. Two wrecks add variety for advanced divers, while natural and artificial reef combinations suit beginners. The Mediterranean Moray, Common Octopus, European Common Cuttlefish and Great Barracuda are the signature sightings, joined by an exceptional range of nudibranchs and slugs. Conditions favour May and October as peak months, with water warming steadily through summer.

Shore entry is possible at Tre Punte and Baia Verde, giving independent divers some flexibility. Panettoni can be reached from either shore or boat. The wreck Relitto Toikosan Maru requires an authorised guided dive.
Volcanic geology dominates the underwater landscape around Catania. Lava rock walls, pinnacles, arches and caves are the most common site types, and the formations at sites like Archi e Grotte were shaped by ancient lava flows reaching the sea. Wrecks at Capo Mulini and the Relitto Toikosan Maru offer contrast, while Panettoni and Baia Verde combine natural reef with artificial structures.
