The dive

A real cave dive inside the AMP: no daylight reaches the chamber, there is a lot of fine sediment and the passage loops back on itself.

Lots of fine sediment: visibility in the chamber can vanish in seconds. Line and good finning technique.

AMP rules (2025, unchanged in 2026): in this cave only with a Cave Diver card (2nd level). On your own only with the AMP's authorisation, in daylight, with at least a 2nd-level card, max 4 divers and within 50 m of the buoy or your dive buoy; otherwise only guided by an authorised centre (guide at least Cavern Diver, max 4 divers per guide). Max 6 divers per dive and 3 dives a day; no night dives.
