(S/E) From the car park at the Veyrier-du-Lac school, cross the village by taking the Route de Morat, then turning left onto the Chemin des Mottes, before joining the Route de la Corniche (no. 48).
(1) Cross this road and head up into the woods opposite via the Chemin de la Merle (listed as Chemin des Mottes by IGN), a path that runs alongside a stream and climbs for about 15 minutes before quickly disappearing into the woods.
(2) At the junction, there is a small scree slope of white pebbles on your right, but turn left. Be careful: the path may be covered in leaves depending on the season. Several side paths lead to the climbing cliffs: stay on the main path, which becomes narrow and exposed; there are a few sections where you’ll need to scramble.
As you approach the cave, a cable is fixed to the cliff face to hold on to. This section is short but exposed: turn back if you do not feel comfortable. In wet weather, the rock is slippery, so caution is advised.
(3) Grotte des Sarrazins (776 m). The return to the car park (S/E) follows the same route as the outward journey.
