This is about the visibility inside the cave, not in the head pool or the open water at the entrance.

Report what your dive computer showed in the cave. Only the number of reports, the temperatures and the latest date are public.

Stingrays often rest on the sand. The roof of the air bubble shines like a silver mirror.

Profile and sections

Stingrays often rest on the sand. The roof of the air bubble shines like a silver mirror.

Depth and profile: A large, open cave with a sandy floor that goes back only a few metres. At the back a shelf ~3 m above the floor, and above it an air bubble that four divers can surface into (a 2008 photo at the air bubble gives 9 m). No maximum depth published.
Configuration: Short and with large openings: recreational gear with a torch; cavern training is wise for surfacing in the air bubble (estimate).
