In the Valley of Trévelo, follow the hillside and go left (junction with the path of the Valley of Trévelo of Limerzel). Many water mills were built along this valley. The creek is very rich in fish. At the end of the woods, turn left on the first road and then quickly, at the cross, go up 30m on the path to the left and turn right on the rocky path. Turn right at the road until the bend of the Grées de Coq and take the grassy path to the left that runs along the hedge. Turn right on the path between the grasses. Go down to the river (steps and footbridge) and climb up a steep path through the undergrowth. The trail turns right and then left. At the road, turn left and, before the farm, take the path on the right. After the houses, get off the road and go down through the undergrowth. After the footbridge, to the right, follow the creek.
