Turquoise to emerald waters!
The Ouysse rises at Espeyroux in the foothills of the Massif Central in the north-east of the Lot département.
What makes this tributary of the Dordogne so special is that most of its course is underground, and its exact course is still largely unknown! In fact, the stream disappears underground at Thémines, only to reappear on the surface several dozen kilometres downstream in the form of resurgences! Two of these resurgences are especially sensitive and well-preserved natural areas that are a must-see. These enchanting resurgences of emerald or turquoise water are the Cabouy and Saint-Sauveur chasms.
There are a number of hiking trails to discover these natural wonders.
Saint Sauveur is well known as a diving spot, but only for professionals!
