Perched at an altitude of 2,247 m, the strenuous hike is well worth the glorious surprise that awaits you here!
Visitor NotificationThe sheep and livestock guard dogs currently at Soi d’en Bas will be returning from the alp on Thursday 15 October. We advise hikers, particularly those with dogs, to avoid this area on that day. From Friday onwards, the area will be clear of livestock guard dogs for the autumn season.
Plan de Soi (route des Rives) – Signal de Soi – Lac de Soi – Cascade de Frassenaye – Plan de Soi
The aquamarine jewel in the Dents du Midi’s crown, this limpid alpine lake is set in an improbable labyrinth of stone artwork, as if surrounded by the ruins of a fairytale civilization.
Departure point on the Les Rives road at point 1206.
Follow the steep trail from Plan de Soi ascending NE in zigzags. At the pass, a path follows the Soi Ridge. After the pastures, the path crosses two rivers and a small ravine to reach the lake. Descend by the same path; if you have the energy, you can take a short detour from the pass, following a trail to the Signal de Soi viewpoint
A little history:
In 1989, Pierre-Marie Cherix brought his brother to visit this magnificent site. The two brothers fell hopelessly in love with the magic of this place, with its sparkling alpine lake and abundant local stone scattered throughout the plateau. The first cairn they built triggered a lifelong passion which has resulted in an intricate dry-stone landscape which showcases the raw, mineral beauty of the Alps.
In the Soi area, in August, September and October, sheep and livestock guard dogs may be in the area.
Camping prohibited.
