Gouffre de Lantouy
A deep spring pool near Salvagnac-Cajarc, about 70 m below a limestone (castine) quarry and surrounded by trees. The cave opens at -8 m in the middle of the basin; a steep slope of pebbles and sand 2 × 5 m wide drops to -44 m 100 m from the entrance, and a difficult squeeze leads on to -52 m. Visibility rarely exceeds 5 m, so it is a short, deep dive.
depth: 0–52 m
