Description
The resurgence of La Doux (private property), was made famous by the exploration of Nicolas Hulot within the framework of the emission Ushuaïa in 1994. It is in this siphon (the longest known in France) of more than 5000 meters of depth that is born the stream of Coly which comes out at 13°C, and which will hardly have time to warm up during its 10 km of race in the open air.
