About Sirena hole
Sirena hole is an advanced Adriatic chimney dive on the Luštica coast for divers who want a rock-walled overhead route rather than open reef. The site drops through a narrow vertical shaft into a deeper exit, so steady buoyancy and relaxed movement matter more than speed. Plan it as a guided boat dive with a torch and choose calm seas for the cleanest entry and passage. It suits experienced scuba divers more than casual holiday snorkellers.
