From Rachou bridge to Lanne-en-Barétous

Just before the Rachou bridge (Vert stream), turn right onto a secondary road (optional, possibility of reaching Aramits opposite). At the Y-intersection of the Escary houses, continue on the path to the left, in the middle of the fenced meadows. Then follow the Aren farm and drive directly on the asphalt. At the Sau bridge, turn left towards the Lanne bell tower and then, 350 m further, turn right to pass under the castle of Porthos. A final push of the battery will take you to a crossroads (stop) where you turn left to return to the starting point.
