Park near the church in Esserts-Salève.
(S/E) With the church on your right, head towards the nearby junction.
(1) Turn right and stay on the tarmac road. Continue to the Mornex Golf Club.
(2) Turn left onto the path leading to the tennis courts, then immediately turn right onto theGR® (red and white markings). Follow the path as it climbs steeply through the woods.
(3) At the signpost “Chemin du Funiculaire”, turn left towards “Téléphérique par Chemin du Funiculaire”. You can either continue along the Chemin du Funiculaire or take the rural path known as the Prévuaz, which runs parallel on the left and is also a mountain bike trail. This option, which I chose, is more interesting as the path winds through the woods, but it is more challenging. Please note ⚠️ this track is used by mountain bikers, so please be careful and give way to them.
(4) At the junction of the two paths, you can either continue on the mountain bike trail or take the Chemin du Funiculaire to have a bit of a rest, as the climb is steep (choice of route).
(5) At the wooden bridge, rejoin the MTB trail on the left, descending slightly through the woods. Keep going straight ahead, maintaining the same direction. This will take you to the Chemin du Funiculaire and then the tarmac road known as the Chemin de la Grange Passey.
(6) Turn right ontothe GR® and head towards the cable car, which is 10 minutes away, not 5 as indicated on the sign. Follow this route to the cable car station. Go up to the terrace and admire the view of Geneva, Lake Geneva and the Jura Mountains (orientation table).
(7) Continue along theGR® towards the Observatory. Pass by Les Treize Arbres and the paragliding launch pad, then stop off at the Buddhist monastery if you wish to rest a while and meditate.
Continue towards the Observatory and along the ridge, admiring the many magnificent views of Geneva, Lake Geneva and the Jura Mountains on one side and the Mont Blanc range on the other. Pass the Observatory on your right and continue along theGR® towards La Croisette. Join a tarmac road and follow it for about 150 m.
(8) At the sign for "Sur la Grande Gorge - car park", turn left towards Esserts-Salève and follow the path through a mountain pasture and then a wood.
(9) At the sign for “Grand Gaby”, continue along the path opposite towards Esserts Salève. Follow this path, which descends steeply after bending to the right.
(10) Turn left, still heading towards Esserts Salève, and continue down the steep path, ignoring the paths branching off to the right or left.
(1) Once you reach the tarmac road at the “Chemin de La Sauge” sign, turn left to finish at the church square (S/E).
