Rocky Sant'Antioco boat dive with gorges, walls, and octopus.
Isola La Vacca is a cluster of six rocky dive spots around Sant'Antioco, with gorges, walls, and boulder fields that create a varied underwater landscape. The area rewards divers who like reading structure and moving carefully through changing terrain rather than simply cruising a featureless bottom. The dives suit a broad range of experience levels and are best approached on settled days, when the rock relief, crevices, and smaller life are easier to enjoy. The appeal is the combination of rugged geology and classic Mediterranean sea life.
