The Roch ar Boch is a spectacular outcrop of rock hidden in the forest of Coat Liou to the North East of Bourbriac.

It is well marked on the map in the car park at the entrance to the forest, but not particularly well marked once you enter the forest itself: follow the trail, and it is round a bend from the tower (La Tourelle), and on a path leading down into the wood.

The path leads down to what appears to be a small group of stones that afford a spectacular view over the forest and the surrounding countryside. More careful investigation, however, reveals these 'stones' to be the top of an enormous outcrop of rock standing on the side of the valley.

The forest is privately owned and closed to visitors during the hunting season - so make sure that you visit during the summer months.
