Things to see and do Villards-D'Héria

Lake Den boasts more than one title. Its waters disappear in the ground and emerged at the Gallo-Roman sanctuary of Villards d'Héria, after an unknown underground journey of 12 hours. Was there a mysteriously disappeared city near the lake? Nothing is less secure. But a temple dedicated to Mars was erected in antiquity. In the th century, the hydrogeological specificity of the site was exploited: hydraulic machines are installed below the lake. Valves are opened and closed to regulate their operation. A beautiful walk on the GR 9 leads to the belvédère rock belvedere which dominates the lake at 961 m above sea level. Do not hesitate to take the climb, because if it is not possible to approach the banks by the bottom, this belvedere offers a superb view of the lake of Den, set in a dark setting of trees and cliffs. Beyond that, we also see the Jura peaks and, in clear time, to Geneva.

Gradually, this little lake envase, it will soon become a simple marsh, then a meadow and finally the forest will take the place, according to an inevitable process natural: . To see it while still time, in Onoz, take the D 3 departmental Road and then turn slightly on the left (D 60). The lake is on your left.
