The dive
This sea cave/spring lies below the ~400 m cliffs of the Baunei coast. Huge halls and formations run inland parallel to the coast. The Ispuligidenie spring, ~100 m further south, connects to it.
Profile and sections
This sea cave/spring lies below the ~400 m cliffs of the Baunei coast. Huge halls and formations run inland parallel to the coast. The Ispuligidenie spring, ~100 m further south, connects to it.
It was explored in the early 1990s by A. Mahler, L. Fancello and M. Slezák (570 m) and in 1997 by the Höhlenforschungsgruppe Kirchheim; lines were laid by Rick Stanton and Markus Schaffhäutle among others. Since 2006 there has been an exploration project led by Thorsten Wälde (SKEP), with 9–11 hour dives and a deco habitat.
- Depth and profile
- Entrance ~-12/-13 m, triangular shaft to -28 m; main galleries -35 to -45 m. Deepest points: -78 m (older source), ~-120/-125 m on recent expeditions (2019: +200 m to a dead end at -101 m). Length: 1,459 m (cadastre, 1997), 3,060 m (DeepDivingAcademy), 4.5 km main passage (Protec).
- Configuration
- CCR suits best; backmount or sidemount with several stages is possible. Nitrox for short penetrations, trimix to go further.
- DPV: DPV-suitable
- Long, roomy galleries (4.5 km main passage); the exploration project uses scooters.
