Park in the Signal car park near the hamlet of Pierre Longue.
(S/E) Take the path opposite, which soon leads onto theGRP® Tour des Monts du Lyonnais. Take theGRP® on the left, pass close to the mast and, at a bend to the left, reach a crossroads of paths.
(1) Continue left along theGRP®, ignoring the paths branching off to the right or left at each junction. This will take you to the hamlet of Les Flaches.
(2) Go round this hamlet on the left, passing the farm in particular. You will then begin a very pleasant walk through the woodland.
As you emerge from the woodland, turn right onto the dirt track until you reach the D113, cross it, then pass through the farm buildings at Le Sapin.
Continue following the red and yellowGRP® markers. Reach the junction with the path leading to Moulin Bernard.
(3) Continue straight ahead on theGRP® to reach the houses at Les Fanges.
(4) Turn right and stay on theGRP® until you reach the junction with the botanical trail. Turn left onto this trail to end up in a park where there are a few tables where you can rest.
Enjoy the view of Saint-Martin-en-Haut.
Note: as the village centre is nearby, it is worth visiting.
(5) Return via the same route to reach the car park where you started (S/E).
