Confluence of 2 streams with basins and waterfalls that give birth to the Dourdon. very beautiful quiet and well-hidden place below an imposing farmhouse (Samson). If you are by bike (MTB or gravel) in the area you can reach the waterfall by coming from the south via a forest path partly practicable for about 800m, the last 100m on foot.

A beautiful cave, a good idea for a family outing. Not very satisfied with the guided tour, though. It's worth seeing nonetheless.

At the old Moulin de Roure it is lovely to bathe in the river (we were there at the end of June). The descent from Aujac is quite steep and can be hot, but the path is well passable.

A cave system over 35 million years old, which was discovered in 1952 and of which only a tiny part is open to the public. You can also stay overnight in the cave for €600/night 😉. Temperature constant 14 degrees. Opening times and admission prices can be viewed on the website. In the off-season there are far fewer visitors on weekdays, so you get more of them.
