The dive

The resurgence lies in the Baume-les-Messieurs show cave. You dive in turbid water with a lot of old line; over 200 m of it was cleared in 2015.

Lots of old line in the sump (partly cleared in 2015): entanglement risk.

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

You carry your gear through the Baume-les-Messieurs show cave to the sump. In 2015 a club team did this during opening hours, among the visitors. No rules for visiting divers are published: ask the show-cave operator for permission.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training.
