High place of pilgrimage (in the region anyway) between the 15th and 18th centuries. The water from this fountain was said to have the power to cure various skin diseases (scabies for example). This pilgrimage ceased shortly before the French Revolution.

A difficult corner off the track on foot or by mountain bike. The sand is soft! One has the impression of being in another region with this dune.

This bucolic path runs along the Stors marsh nature reserve. The ground quickly becomes muddy in bad weather and the days following the rain. That said, the setting is beautiful along the rock faces. For the rest, it's a fairly easy single.
