Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.

The dive

Sea caves with shrimp, the odd catfish and walls full of soft corals. In the Bat Cave a layer of sulphur-rich water below the surface gives a misty effect.

The first cave starts with a hidden entrance at -30 m and a narrow passage: for Advanced divers only.
