There is a monument there commemorating the local resistance fighters, who used this meadow to parachute in equipment for the British secret services during the Second World War.

A stronghold of resistance and an ancient milestone on the Sardinian road that led to the Netherlands in the 17th century. A very beautiful view of the Jura Mountains, too.

Nice place. Too bad the forest was destroyed by large machines going up to cut down trees. This makes traveling by mountain bike very difficult. Nice place anyway.

Magnificent small summit with a view of the Alps and the Mont-Blanc massif. Depending on whether you go through the back or over the ridges, the ascent can be easy or technical and tricky. There is a bench at the top to enjoy the view.
