The GR738 pays homage to the pastoral and mining past of the massif, where iron was once extracted. From the north, the ascent towards the Col de la Perche and Col de la Perrière plunges hikers into a world of granite solitude, far from ski lifts. The demanding and technical route then crosses the Col de l'Aigleton to reveal magnificent panoramas of the sharp peaks of the range, a veritable crystal spine. Water is the other jewel of this journey: the legendary Lac du Crozet, with its famous spillway that feels like the end of the world, reflects the surrounding peaks before the trail reaches the Chamrousse resort. The final descent towards Vizille crosses the Lac Luitel National Nature Reserve, the oldest in France, protecting an exceptional peat bog and a fragile biodiversity inherited from the last ice age.
