Cala Goloritzé, Sardinia
Must-DoIconicThe limestone arch, the pinnacle, and absurdly clear water — snorkelling off the beach here reveals posidonia meadows, damselfish, and octopus. Reach it by boat from Cala Gonone or a 1.5-hour hike.
Riserva dello Zingaro, Sicily
Must-DoSeven coves with rocky entry and excellent visibility. Cala dell'Uzzo and Cala Marinella are the best for snorkelling — bream, sea urchins, and colourful wrasse among the rocks. Bring your own gear; no rental inside.
Portofino Marine Park, Liguria
Must-DoSnorkel at Paraggi beach or San Fruttuoso to see the Christ of the Abyss statue at 17m (visible on calm days). Grouper, moray eels, and sea fans close to shore in the protected zone.
Isola dei Conigli, Lampedusa
IconicThe most famous beach in Italy — turquoise lagoon with sand so white and water so clear it looks tropical. Snorkelling the rocky edges reveals parrotfish and loggerhead turtles (nesting season Jun–Aug).
Panarea, Aeolian Islands
Hidden GemVolcanic rocks and thermal vents create a unique underwater environment. Snorkel at Cala Junco (a prehistoric bay) for warm-water fish and bubbling seafloor. The smallest Aeolian island with the clearest water.
Our pick
Sardinia's east coast (anywhere from Cala Gonone south) has the best snorkelling water in mainland Europe. Lampedusa for the full tropical experience.
