Your starting point is the Parc de la Vallee de l'Aure, the riverside park at the foot of the old town — about a 5-minute walk from the Bayeux tourist office. This is self-guided: no guide meets you. Just start at the park and follow the route on your own phone.
The route finishes at the Museum of the Battle of Normandy on Boulevard Fabian Ware. From here it is about a 10-minute walk back to the cathedral and the old town.
