Hike to the Lac de Lauzon (1998 m.) to enjoy views of the Cirque glacière du Gioberney at the head of the Valgaudemar valley in the Écrins. The cirque is surrounded by a number of peaks of more than 3500 m. and their glaciers. A wonder to walk this landscape early after the snow melt when the footpaths become practicable again without technical alpinism.
