Barrage d'Arzal walks

A country walk between Cosca, a stone's throw from the Arzal dam, and the Templar village of Lantiern.This walk along beautiful tree-lined paths and a few small roads connects the banks of the Vilaine estuary to the beautiful Saint-Jean-Baptiste Chapel, through pleasantly rolling countryside.The end of the route follows the botanical trail.The trail has been modified after the point (1), following the clear-cutting of the wooded area it used to cross, which made the trail disappear.
