About Grotta delle Stalattiti
Grotta delle Stalattiti is a submerged karst cave at Punta Giglio near Alghero, inside the Capo Caccia - Isola Piana marine area of northwest Sardinia. The route follows smooth limestone into a larger chamber with old stalactites, a former sea-level mark, and an internal air pocket, so the dive is about careful overhead movement and slow navigation rather than open-water cruising.

Scuba Diving
Primary points of interest include submerged stalactites and a marked old sea-level line near the entrance around 7 m, with a ~50 m penetration to an air pocket after a 90-degree turn.
Freediving
Not a freedive-first site; the overhead section and air-pocket route make it a scuba cave dive rather than a breath-hold swim.

Not a practical snorkel site; the interesting section is submerged overhead cave passage, not the surface.
