a pretty little village not to be missed in the Yvelines: you wouldn't think you were in the suburbs of Paris!

Beautiful forest between Garancières and Bazainville with many trails, perfect for gravel or mountain biking. Don't miss the small, very wild Pimardière pond. A small path allows you to go around it.
