The Brougnat

Go around the lake to the right in the undergrowth as close as possible to the fence.
On leaving the wood, descend to the right above the weir.
Cross a wet zone, pass in the middle of the hedge of trees. Then turn immediately right, walk along the edge of the forest and join the chemin du Brougnat. Take it to the left, pass in front of beehives, climb through the undergrowth to recent buildings, and come out on the D24.
