Saint-Guérin Dam

Highlight • Other

Imposing arch dam that was completed in 1961. The building can be walked on freely, but the hiking trail on the west bank has been closed since 2015 due to the risk of falling rocks. In order not to put yourself in danger, you should turn around here and hike to the suspension bridge on the east bank and back the same way.

Lake Saint-Guérin

Highlight • Lake

Lac de Saint-Guérin was built in 1961 as part of a hydroelectric complex, which also includes nearby Lac de Roselend and Lac de la Gittaz.

The car parking around the north-western edge of the lake is a great place to access many different trail running Tours in the area.

There's a buvette selling drinks and snacks between June and September and also a public toilet on the lake shore.

Himalayan footbridge of Lac de Saint-Guérin

Highlight • Bridge

The Himalayan suspension footbridge that crosses the gorge at the southeastern tip of Lac de Saint-Guérin is a truly spectacular site. Spanning the turquoise waters of the lake between its rocky edges, it allows access to the southern end of the lake and the trails up towards Cuvy and the Grand Mont.

The bridge is constructed from steel grids, so you can see between your feet down to the sunken trees and rocks beneath the water. These are remnants of a former valley flooded to create a reservoir to provide hydroelectric power.
