The Tremiti Islands deliver a diving landscape built around walls, pinnacles, caves and reef structures, all draped in Red Gorgonian and Yellow Gorgonian. Advanced sites such as Gli Archi and I Picchi di Elena drop to serious depths with drift conditions, while shallower beginner reefs and the freshwater cave dive at Lago di Capodacqua broaden the range considerably. Mediterranean Moray, Conger Eel, Scorpionfish and the occasional Ocean Sunfish are reliably observed across the sites.
