Gorges du Pichoux and Lac Vert

The Undervelier region lies at the heart of the Gorges du Pichoux, which are listed in the federal inventory of natural landscapes, sites and monuments. This typical gap in the folded Jura houses springs of remarkable quality. An extremely rare species of mayfly (Baetis nubecularis) was discovered here in 2002. It is only found in the cold and oxygen-rich waters of the Jura.
Nearby, the valley of Soulce boasts diverse vegetation with an extraordinary variety of plants and wilflife. Here you will find varied environments ranging from rough pastures and areas with more than 20 species of orchid to the springs where the streams teem with salamanders.
