Moiry via ferrata

Grimentz - This is graded TD (very difficult) and gives a vertiginous view of the Moiry dam. This extraordinary via ferrata is a must for all experienced aficionados!

The Moiry via ferrata is practicable from the beginning of June to the end of October, depending on the weather conditions. Vehicular access depends on whether or not the road to the Moiry dam is open. Outside these periods, it can be reached on foot (1½ hours’ walk from Grimentz).


From the car park at the foot of the dam, follow the road for 150 m, then take the track that goes up on the right to join the starting point of the via ferrata.
