The dive
You pass a hydrogen sulphide layer and haloclines into clear fresh water; visibility is excellent after that. The walls are full of fossil shells, there is a colony of large mussels, and you see pillars and stalactites.

You pass a hydrogen sulphide layer and haloclines into clear fresh water; visibility is excellent after that. The walls are full of fossil shells, there is a colony of large mussels, and you see pillars and stalactites. There are two jumps in the line.
Risorgenza di Cala Luna is the perennial freshwater spring of the Codula Ilune karst system, with two branches. It was surveyed in 1990 by Czech cave divers (Prague/Olomouc); Protec is looking for a connection to the other side of the mountain.
- Depth and profile
- High, narrow gallery at -12 to -15 m for ~500 m; one chamber drops to -37 m (cadastre), the centres quote max -40 m; average ~-14 m. Surveyed 634 m, plus ~1,500 m of side passages (Hasenmayer).
- Configuration
- Backmount and sidemount both work; a narrow gap makes sidemount more comfortable. Air or nitrox.
- DPV: DPV possible (estimate)
- ~500 m gallery, high but narrow: a scooter is possible but gains little.
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 40 m (trimix or deco may be needed)
This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
By boat from Cala Gonone to Cala Luna; the entrance lies a few tens of metres south of the beach below a high cliff and is barely visible from the boat. Entrance partly above water.
