Map and photos


To reach the starting point of the Via Ferrata de Moiry, head towards Grimentz village. If arriving by car, take the A9 to Sierre, then follow the road into Val d’Anniviers toward Vissoie, then Grimentz and continue towards Lac de Moiry until you reach a parking lot beneath the dam. Note that there may be Winter closures depending on snow conditions. If traveling by train or bus, take the postbus from Sierre to station Grimentz, Torrent, right under the dam. Return by bus is from Moiry VS, Barrage station, near the restaurant at the eastern end of the dam, where you descend after finishing the route.

Approach to start

Follow the road uphill until you see a steep path leading to the entry point, well marked by a sign, before the car tunnel.

The route

The route winds its way up the valley’s right side (on your left as you look up from below the dam), offering shaded climbs in the morning. As you ascend, marvel at the imposing arch dam below until you surpass its height and are rewarded with panoramic views of the turquoise Lac de Moiry and snow capped mountains in the distance, where you can see the Moiry glacier as well.

Notably, since 2009, a suspension bridge adds an extra element of excitement to the experience. A zip line (tyrolienne) is also available, where you need to bring your own pulley.

Before the net there is a wooden table with benches, where you can stop and have a snack while still being clipped to the wire. Climbing the net starts on one side of it, then you cross on the other side, this time slightly overhanging.


Follow the small footpath towards the dam and the restaurant near it. Here you’ll also find the bus station to return down in the valley. If you parked the car at the beginning of the route, cross the dam on foot and descend on a path on the other side.

Good to know

  • Open from June to mid/end of October
  • Built in 2005, with the bridge added in 2009
  • The long, narrow, winding road to the start makes the trip worth it all by itself
  • You can visit Grimentz village when coming to or returning from the Moiry dam
  • After the dam you can follow the road up to Lac de Châteaupré, where the bus has a station as well
