Dive-site story
Located along the volcanic coastline of Ustica within its marine protected area, Grotta Totò is a wide cavern system featuring volcanic rock formations and vaulted ceilings. Diffused ambient light filters through the main entrance, illuminating rocky recesses where invertebrates take shelter. Divers traverse sandy patches and rocky ledges before penetrating the sheltered interior chambers, requiring steady buoyancy to avoid disturbing bottom sediment.
