On the Divonne-les-Bains forest road, after 500 m, park at the Fleutron reservoir car park, the starting point for walks.
(S/E) Take the track that climbs gently to the left and follow it, staying firmly on the main track.
(1) The track levels out slightly here; this is the only challenging part of the route. Continue to the Carrefour du Comte (signposted).
(2) At the crossroads, turn right onto the bridle path for an almost level stretch through the forest with a few views of Lake Geneva, the Alps and Mont Blanc in the background.
(3) The track crosses the path leading to the Jura peaks (a quick descent is possible). Continue along the track until you reach the forest road.
(4) Head down this road to return to the car park (S/E).
