Country walk lasting about one hour. Visit recommended from end of April to start of September. Wear boots if it has been raining. Respect the silence and the cleanliness of the site, At the start of the route, upstream from the waterfall, you will see Lammerville Castle, about which very little is known (no doubt built by the Hotot family, then destroyed by Richard Lionheart... while Lammerville was in England). Lammerville centre is a listed site. The electric and telephone cables have been buried.
From the Town Hall car park, descend to the church, take the bridge over the Vienne and make your way to the wayside cross at the start of the route. Follow Chemin des Chasse-Marées. Continue through the forest for about 1.5 km before visiting the panoramic viewpoint over the hamlet of Flamanville, on the way out of Folie Forest. Descend towards this hamlet to the D127 and return along this road to the centre of the town.
