Pleasant, cool, shaded, to do during the week, not crowded! On the other hand, avoid on weekends and by bike, pedestrians don't pay attention, dogs are at granny's, children are not kept in check... etc. 28 km of flat.

Here, on a clear day, you can admire one of the most unique views of the Parisian skyline, even though it is 40 km away, with the silhouette of La Défense, the Eiffel Tower and the Montparnasse Tower.
