I loved it, it's a shame that once we got to 500m from the ferry we had to make a big detour by road to take the Quellebeuf ferry to get to Pont Audemer... but I'd do it again

Beautiful walk among the thatched cottages and in the forest. This route, rather flat, is accessible by mountain bike because the paths are passable.
