Please note: there are two tricky sections between points (9) and (10); ropes are in place.

Start from the large car park situated in the middle of the Solaison Plateau. Access via Brizon (A40 Bonneville exit) or Mont Saxonnex (A40 Marnaz exit).
(S/E) Head towards the roundabout, then follow the road towards Pointe d’Andey for approximately 200 metres.
(1) At the first junction, turn right between the houses. You’ll come to a fork in the road.
(2) Follow a small sign indicating a right turn (north). You’ll then begin the climb up through the mountain pastures; the slope is short but steep, straight up the hillside, with hardly any flat sections. Look back from time to time to admire the view. You’ll reach the Pointe d’Andey (views of Lake Geneva, the Salève and the Arve Valley, as well as the Bargy Range and the southern face of Mont Blanc).
(3) Then continue westwards, begin your descent and, after a few minutes, you’ll reach a pass.
(4) Turn left towards the Plateau de Solaison. The descent becomes less steep. You’ll reach the junction you passed earlier on the way up.
(2) Carry on straight ahead and rejoin the road.
(1) Follow the road to the right for about 500 metres and you’ll reach the Col de Solaison.
(5) Head south towards the Rochers de Leschaux via Les Berriers. After 200 m, turn left.
Initially, the path through the forest is easy, then you’ll start climbing up through the sharp limestone pavement.
Take great care: even in dry weather, the rock is slippery. Follow the yellow markings (or any other painted markings).
Reach the summit of the Rochers de Leschaux at an elevation of 1936 (views over Lake Geneva and the Bargy and Bornes ranges).
(6) Head towards Solaison via the Grotte de la Glacière. The path is easier on the descent but remains slippery nonetheless. You will eventually emerge from the sharp limestone pavement. At the fork in the path, turn left until you reach another fork.
(7) From this junction, you can:
- head straight to the junction at Le Perthuis by turning left.
- or make a round trip to the Col de Cenise by turning right and following these directions. From the Col de Cenise, you can see the altiport, as well as a stunning view of the Bargy Massif and the Plateau de Cenise with its grassy slopes.
(8) Retrace your steps back to the fork.
(7) Turn right to reach another fork – Le Perthuis.
(9) Turn right towards Solaison and head for the Grotte de la Glacière. Beware of difficult sections: a ravine on your right, followed by two sections with ropes to help you descend.
The path is narrow in places, then you reach the cave.
(10) Continue along the rest of the path, which is straightforward: first downhill, then slightly uphill until you emerge from the forest and reach the road.
(11) Turn left onto the road, heading uphill towards the car park where you started (S/E).
