Randonnée pédestre

Mysterious canyon


A track from Tête-Noire takes you down to the bottom of the gorge in 25 minutes. Here, there are 120 metres of footbridges above the river, from which you can look down into the Nymphs' Cave. Allow an hour for the walk back.

Take the 120-metre footbridge above the river to reach the bottom of the gorge where you can admire the mysterious and impressive Nymphs' Cave.

The return journey is partly via the former international road section (footpath) linking Martigny to Chamonix.

A slightly longer track also enables walkers to reach the Mysterious Gorge from Finhaut.
