This route passes through the three hamlets that make up the municipality. It leads from the valley to the sea, where you will discover the little resort town of Pourville-sur-Mer and its beach enclosed within two cliffs. The next part of the loop will take you to the Bernouville coastal woods, a natural, unspoilt area at the edge of the Alabaster Coast.
Departing from the beach in Sainte-Marguerite-sur-Mer, this hike will lead you to Cape Ailly and its clifftop lighthouse. You will pass through Ailly Woods, one of the region’s three Special Areas of Conservation. Its subsoil and the species that populate it make this spot one-of-a-kind in Upper Normandy.
The 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.
