The GR21The GR21 national hiking trail runs the whole length of the Seine-Maritime department.
In Dieppe, the trail begins on the cliff, at Notre-Dame de Bonsecours Chapel, and heads out towards Le Tréport (to the northeast). The distance between the two towns is close to 35 kilometres. It is a chance to visit the hanging valleys forming the connection between the cliffs.
If you head southwest, in the opposite direction, the route features many remarkable viewpoints in both Pourville-sur-Mer and Varengeville-sur-Mer.
