Waymarked with a red ring, this loop starts at the Étang de Hanau and reaches the Erbsenthal valley: it passes the Erbsenthal cave and pond (Erbsenweiher), a stone's throw from the chapel of Notre-Dame-des-Bois. It then climbs to the Erbsenfelsen sandstone arch and returns past the ruins of Waldeck Castle.
A good day's walk, or a long half-day for regular walkers.
