This walk is a summary of south facing slopes in the Valgaudemar area. It starts in the warm scree that it more or less vegetated. It then progresses over lawns and moors of juniper, blueberries or bearberries... They give way to mountain ash, whitebeam and amelanchiers indicating that the forest will soon take over. Higher up, the beech forest casts shade on the walkers, next a beautiful larch forest is a sign that the forest environment will give way to the high altitude moors and lawns. The Lautier lake and the surrounding ponds are a haven for aquatic species. Still higher, is the realm of rocks and chamois.
