Satoriz, Ornex to Divonne

This route avoids roads busy with vehicles as much as possible.

Coming from Divonne, the single track "chemin de la vie du pont" passes the Old Mill house on the left and then takes a left turn to circumnavigate a field, which avoids vehicules but which may be muddy depending on the recent weather.

After Villars Dame the route enters the trees where one needs to look out for a right fork off of the main track (not recorded on the map database); the designated left turn before the CERN outpost is doable but difficult.

Note also that the Chemin des Trevys is unmade and will be very muddy in wet conditions.
