Start from the roadside of the D 9. Take the path lined by ash trees that heads west. Once you are on the heights of the Can de l’Hospitalet, take the path on the right that goes down into the Tarnon valley. NB: The path may be difficult to see. Follow this small steep path to where it crosses the Broussous trail, and turn right towards L’Hospitalet. At the next crossing, continue straight. The path becomes rather steep for a few metres. At the next crossing, turn right to return towards L’Hospitalet.
