Lac de la Muta walks

This beautiful circular route takes you from valley to valley, each time revealing a new landscape, from a wild valley to the lakes around the Refuge des Merveilles in a stunning rocky setting.

TheGR® 52 is a route that crosses the Mercantour National Park, through the Alpes-Maritimes from Saint-Dalmas-de-Valdeblore to Menton. ThisGR® route is very challenging due to the varied terrain and significant elevation changes. You’ll reach altitudes of up to 2,700m, where you can admire the high-mountain landscapes, flora and fauna. Then, in the second half of the route, you’ll encounter panoramas that are more southern in character but just as extraordinary.

The fifth stage ofthe GR®52, where southern landscapes give way to mountain scenery. Challenging due to its elevation gain, this stage follows the old Italian border, where you’ll discover numerous military remains. Notably at Authion, where one of the last battles in France took place, resulting in the deaths of 273 French soldiers just a few weeks before the armistice of 8 May 1945. The views here are fabulous.

The first stage of a three-day trek in the heart of the Mercantour National Park, this route immediately takes the hiker into the high mountains via a little-used alpine route, away from the classic Pas de l’Arpette. On the itinerary: a steady climb up the Vallon des Verrairiers from the Gordolasque Valley, crossing the Pas du Trem (2,477 m) at the foot of the legendary Cime du Diable (2,685 m), then a long descent past a string of glacial lakes – Lac du Diable, Lac de la Muta, Lac du Trem, Lac Fourca – down to Lac Long Supérieur and the Refuge des Merveilles (2,130 m). A route combining the geological richness of the upper Gordolasque, breathtaking views of the Authion, Mont Capelet Supérieur and the Mediterranean on clear days, and a majestic entrance to the Vallée des Merveilles, a site listed as a Historic Monument. Characteristic wildlife: chamois, ibex, marmots.
