Source du Solnan

River 61.8 km long before it flows into the Seille.
This Vauclusian type spring is a karstic emergence whose waters come from Val d'Epy (Jura). In rainy weather, it feeds a resurgence in the rock and a cavity called "Le Dauphin". In case of exceptional rainfall, the Dauphin releases a magnificent waterfall on the cliffside.
