Le Chemin de Grande Randonnée GR2, a long sign-posted trail, goes from Havre to Dijon, passing by Paris. It follows the loops of the Seine, passing by Courcelles sur Seine, 6 kilometers from La gentilhommière de Normandie which will be delighted to receive hikers who want to rest in its charming Bed & Breakfast rooms.

An excellent internet site has been done by the local schools:
