Via Alpina Red R125

Modane - Granges de la Vallée Etroite

Covering 20.7 km, this demanding trail is best tackled by experienced walkers in good condition. Budget roughly 4 hours and 36 minutes or consider splitting it across two days.

This linear trail moves from one end to the other without looping back. A return journey by transport — or retracing the path — is needed to get back to the start. The trail is officially waymarked as VA-R125, so look out for the trail markers along the way.

Part of the International Walking Network (IWN), this route connects to a continent-spanning long-distance trail system. It meets the highest standards of waymarking, surface quality, and route documentation.
