Émergence du Martinet
Closed to divers
Not accessible to divers: the spring is not on the CDS du Lot's list of sites where diving is allowed (November 2026). According to the CDS the other springs are closed, for example because the owner refuses or because drinking water is pumped there.

Profile and sections
You go in through an entrance shaft of 1 x 0.7 m. Beyond it is an oval passage, 2 m wide and <1 m high, with 6–8 m visibility going in; sand, silt and clay make it variable on the way out. A permanent, measured line with two T-junctions is in place, the first at 40 m. The cave is 805 m in total; allow ~2 hours to S3 and back.
Practical: the pool is very small, so two divers at a time at most. The Martinet is 600 m from Gouffre de la Berrie.

How to get there
Commune of Catus. From Catus head for Saint-Médard, past the Lac Vert; after the lake leave two roads on the right. The spring is at the second right-hand bend, on the right behind the trees, ~20 m from the road. There is room for two cars one behind the other: reverse in, or getting out after the dive is very awkward.
