Gyr (cours d'eau) - Affluent de la Gyronde walks

This third stage of the crossing of France, following the 45th parallel as closely as possible, is long and difficult but absolutely magnificent. You will discover or rediscover the two jewels that are the Écrins and Meije massifs. Most of the route is on the GR® 50 and GR® 57. The paths are well marked and well maintained. This stage can be divided into four sections: 1) an ascent to the Col du Chardonnet; 2) the descent to Lauzet; 3) the ascent to the Col du Lautaret; 4) the descent to Arsine.

A beautiful hike with magnificent scenery. The climb to the Ricou refuge is a little steep but not particularly difficult. Once you reach the circular path, the route is very easy, almost flat until you reach the Torrent de la Cula. The view over the entire valley is truly superb. From the lake, the trail descends to Laval.

A beautiful and challenging hike in the hills, varied with some unexpected sections. Stunning views. Be careful, there are many tricky and slippery sections. Avoid in wet weather.

From the Vallonpierre refuge, the hike takes you to the Rif du Sap chapel, then to the charming village of La Chapelle-en-Valgaudémar, where you can stop for refreshments at a local grocery store. The route then crosses the Valgaudémar National Forest before reaching the magnificent lakes of Pétarel and Sebeyras.

The hike begins with the ascent of the Pas de la Cavale, which rises to an altitude of 2,735 metres. After this climb, you will reach the Pré de la Chaumette refuge. From there, another climb will take you along the imposing Sirac, passing through the Vallette, Gouiran and Vallonpierre passes. The route ends at the Vallonpierre refuge.

Between forest, mountain pastures and the banks of the Clarée, this walk takes you gently from Névache to the upper Clarée valley. It is also an opportunity to discover the hamlets and isolated chalets scattered throughout the valley. Don't forget to admire the pretty Fontcouverte waterfall on the way! Please note that if you do this hike outside the shuttle bus operating period (information available from the tourist office), you will have to walk back to the starting point along the same route!

For this first stage, you will begin your journey at the Argentière-les-Écrins train station. The hike follows the GR®54A, taking you through the Fournel valley and the Deslioures biological reserve. You will finally arrive at a plateau that is ideal for camping. Please note: landslide in July 2025
