Grand Montoir is the nicest route to lead to the Parmelan.
The steep path climbs through a weakness of the rock face. The fast height gain with the help of chains and rails seems magical but the difficulties remain moderate for experienced hikers.
From Annecy, take the N 203 and turn right to Villaz. Follow the D 5 during 1 km on the left in N direction. Turn right and take the forest trail of Parmelan (signs) till the end. Park.
Follow the path on the right through the forest. In 20 minutes, you arrive to Chalet Chappuis. Nice view on the Annecy town and lake and on the Lanfon teeth.
Climb steep to the Parmelan cliffs and follow the foot of them on the left.
At the fork, turn right and enlist in the Grand Montoir.
The ascent becomes magnificent in the middle of the cliffs. The path is airy and steep, but good ensured with handrails and chains. The level difference is rapidly climbed and you open out into the Parmelan plateau.
Continue through a karstic landscape. After a short ascent, you arrive to the Camille Dunant Hut. The summit is now very near on the right.
Crampons are absolutely necessary if the Grand Montoir is snow-covered.
