A nice walk to the waterfalls of Cernay in the Valley of Chevreuse 1 h from Paris.
A pleasant walk in the Valley of Chevreuse. The departure of the walk is not difficult to find, there is a parking lot right next to the starting point. Then simply follow the path along the stream or climb on the top of the hill to discover this nice place. The walk along the river is quite short. Alternatively, you can visit the Abbey of Vaux de Cernay, which is located a few kilometres away. Beware, there is a large wall that surrounds the Abbey, to go inside you have to to make a detour and walk on the road.
