A nice walk to the Cernay waterfalls in the Chevreuse valley park, 1 hour from Paris.
A nice Sunday walk in the Chevreuse valley to get some fresh air. The start of the walk is not difficult to find, there is a parking lot right next to the starting point. Then you just have to follow the path along the brook or go up on the top of the hill to discover this beautiful place. The walk along the creek is quite short. You can also take the opportunity to visit the Abbaye des Vaux de Cernay which is located a few kilometers away. Be careful, there is a big wall surrounding the abbey, to get inside you have to make a detour and walk on the road. It is better to take your car to get to the Abbaye des Vaux de Cernay.
