The dive

The entrance is a muddy chamber full of bats, and the water starts brown and murky. Sinking through that layer, you enter what Phillip Lehman called 'the most decorated cave anyone has ever seen'.

Brown water near the surface with almost no visibility, with rotting bats, cockroaches and centipedes.

The entrance is a muddy chamber full of bats, and the water starts brown and murky. Sinking through that layer, you enter what Phillip Lehman called 'the most decorated cave anyone has ever seen'.

In 2014 the team heard rumours of caves 80 km north of Toliara. The villagers at first would not have their sacred places disturbed, but after seeing footage of cave dives elsewhere, chief Fahazoa performed a cleansing ceremony and the team was allowed in.

Practical: only with an organised expedition, permission and the ceremony.

Depth and profile
The first dive went to 22 m; maximum depth not published. Axolot does a shorter dive here without a stage.

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

In the Mikea Forest, on the tribal land of the late chief Fahazoa's village: a longer hike through the forest, then a steep slope with thorn bushes and big boulders. A ceremony is needed before you enter the water.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Nov 2026): the XDEEP Exploration Support Program's project pages on the Mahafaly Karst Exploration Project (2013–2019), the Madagascar Cave Diving Association and Axolot Diving Expeditions' trip programme. No cave has a public coordinate: pins are missing on purpose. Certification and configurations are estimates.
