Heritage & Nature

Keep your eyes peeled! The scenery you pass through is not only beautiful, it’s full of secrets and age-old traditions:

The Lac du Plan du Rocher: This lake occupies a “glacial depression”. Thousands of years ago, when the glaciers retreated, the relief was sculpted, leaving these natural hollows on the Chavannes plateau, which then filled up with water.
The “Mouilles”: In Savoyard dialect, a “mouille” is a damp area or spongy ground. On this slope, water stagnates on the flats, creating mountain marshes that are essential to local biodiversity (and where you may be lucky enough to spot the famous tadpoles that give their name to the trail!)
