Lac Bleu, Mountain lake in Val d'Herens, Switzerland
The Lac Bleu reflects deep blue waters at 2090 meters elevation, surrounded by dense larch forests and rocky mountain slopes in the Valais region.
The lake formed through natural geological processes during the last glacial period, when ice movements carved the depression in the mountain landscape.
Local mountain guides regularly lead groups to the lake while sharing knowledge about Alpine flora, geology, and traditional Valaisan mountain life.
A marked trail from La Gouille takes visitors to the lake in 45 minutes, with mountain restaurant Chez Leon offering refreshments along the path.
The lake's water flows from a spring located 10 meters above, containing specific algae and glacial clay that create its characteristic blue color.
