Park in the car park near the customs office on Route du Pas de l'Échelle.
(S/E) General direction: Château de Monnetier in the hollow between Grand Salève and Petit Salève (visible from bus stop 8 in Veyrier-Douane).
After the Veyrier customs office (400 m above sea level), cross the D1206 (formerly the N206), which connects Annemasse to Saint-Julien. Continue straight ahead towards Salève. 200 m after the D1206 (formerly the N206), cross the railway line. Continue straight ahead and pass the restaurant "Au P'tit Four'No" on your left. 30 m further on, avoid Impasse de la Touvière and turn left, following the road towards Annemasse (Chemin du Bois Mériguet, parallel to the railway line for 150 m). 300 m further on, cross the bridge over the A40 motorway.
(1). After the bridge, turn left and after 20 metres, turn right, leaving a house on your left. 20 metres further on, behind some stone blocks, you will find the edge of the forest and a sign saying "Monnetier: 1 hour; Orientation table: 2 hours 35 minutes; Croisette: 4 hours; Pas de l'Echelle (Bourg): 0 hours 15 minutes". Follow the fairly steep path, which climbs in large switchbacks (markings and protective barriers where the slope is steep). After about 40 minutes, you will arrive at a commemorative plaque.
(2) Take the stairs and climb the 110 steps (partly carved into the rock, with an iron handrail). The path leads to the exit of the disused railway tunnel on the Monnetier side. Turn left and pass the entrance porch of the Château de Monnetier on your left. 200 m further on, you will arrive at the church of Monnetier (700 m above sea level).
(3). From Monnetier Church (700 m), turn right onto Route des Deux Salèves. Cross the D41A and continue along Rue Bernadette. Return to the D41, follow it for a few metres on the left and take a wide path ascending to the right that runs alongside a private property (chalet). Pass an old quarry on your left. Further up, after a left-hand bend, turn right onto a narrow path that initially follows a small rocky ledge. Pass an ammonite fossil and you will arrive at an oratory.
(4) From this oratory, take a path ascending to the left into the forest. (Caution! On the descent, 20 m upstream from the oratory, there are rock slabs that are very slippery when wet: please be careful). Reach the D41A road 150 m downstream from the Croix restaurant (890 m). Cross the road and continue uphill, veering to the left. The path crosses the road four more times. Pass to the right of the former Hôtel-Restaurant du Mont Blanc (1050 m), then, further up, to the right of the CAS chalet.
(5) You will arrive at a four-way junction (1080m): on the left is a private road to Grange Passey; on the right, a path leads to the upper station of the cable car. Continue straight ahead until you reach a bridge, then the old Treize Arbres station (1150 m, a former restaurant). Walk up Chemin des Treize Arbres until you cross the D41A again.
(6) Cross the road and walk diagonally across the fields to the left towards the antenna. Climb the stairs and cross the children's playground on the right, then cut across the D41 twice. You will arrive at an old orientation table and a take-off area for paragliders and hang gliders (1212 m altitude).
(7) The antenna is 300 m ahead on your left.
(8) The descent follows the same route as the ascent (S/E).
