Source Bleue

Source Bleue is a karst spring near Touzac that brings underground water to the surface, feeding directly into the Lot River. The spring emerges from limestone formations where water travels through hidden cave systems beneath the ground.

The spring was known by the name Fontaine de Cach during the Middle Ages, indicating it held local importance long before modern times. A mill was built near its waters around 1464 to harness the water's power for grinding grain.

The spring has been a source of fresh water for people living nearby for hundreds of years, shaping how communities settled and organized themselves around it. Local residents still view it as an important part of their landscape and daily connection to nature.

The spring is reachable from the D65 road just south of Touzac, with a short walk to reach the source itself. Sturdy shoes are a good idea since the ground can be wet and slippery near the water.

The spring functions as an exsurgence, where groundwater naturally flows up through the Earth without being pumped or directed by humans. This type of water emergence is relatively uncommon and shows how complex the hidden geology beneath the region truly is.
