A lovely spot for a picnic. There's even a crêpe vendor. You can cross the Seine by ferry. Bicycles are welcome. Check in advance for opening and closing dates.

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.
