Zia Lisa is a boat-accessed cove on the southern side of Ustica, known for crystal-clear water, boulder-formed passages, and a cave-and-wall landscape that creates strong light effects. The walls carry Astroides, sponges, starfish, and bryozoans, while the passages can turn up large groupers, moray eels, octopus, and nudibranchs. It suits divers who like terrain-rich dives with steady control through rock openings.
