Cime de la Vallette de Prals (2496m) walks

The aim of this fourth stage is to reach the Merveilles mountain refuge. The route is less well-travelled than the classic one via the Pas de l’Arpette. You’ll discover the Verrariers valley and the Pas du Trem. This small pass lies at the foot of the Cime du Diable, which you simply must climb. This magnificent viewpoint offers a 360° panorama of the Mercantour, as well as the Authion, the Col de Turini and all the way to the sea. You’ll then walk alongside the lakes of La Muta, Le Trem and Fourca.

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.

Discover the Vallée des Merveilles by connecting the Vallée de la Gordolasque to the famous Refuge des Merveilles.

This third stage is less demanding than the previous two. The entire route follows a marked path. Only the start of the descent from the Pas du Mont Colomb and the sections over scree require a little care. This is the classic route linking the Madone de Fenestre valley with the Gordolasque valley. The scenery along the way is magnificent, and the Pas du Mont Colomb offers two completely different views from its eastern and western sides.

This second day will take you to the foot of the Cime du Gélas (just 200 m below the summit); you’ll walk for a long time alongside Lac Long and the superb Malédie. You’ll then head into another small valley to admire the Cime Saint-Robert. The Lac Blanc, from which the stream flows, is none other than the Vésubie, and of course, the Gélas on its western face. The route will become more familiar and less strenuous once you rejoin the path coming from the Lac de la Fenestre.

This route, which runs parallel to the border, is dominated throughout by the large peak of Gélas, the highest summit in the area.

Starting from the Refuge de Nice, the fourth stage of this journey through the Mercantour is the shortest. Short but just as difficult. You’ll pass the Baisse du Basto, the highest point ofthe GR®52. You’ll cross over to Lac du Basto, then it’s the climb up the Baisse de la Valmasque, before descending into the Vallée des Merveilles.

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.

This itinerary allows you to discover the wonders of this valley. In particular, the famous engravings such as Christ, the Tribal Chief and the Altar Rock. But be careful, these areas are monitored!

This final stage will take you back to Castérino via the ascent of Mont Bégo. From the summit, you’ll look out over the Vallée des Merveilles. You’ll catch sight of the neighbouring peak opposite, the Grand Capelet. You’ll enjoy a 360° panorama stretching from the Argentera to the Mediterranean. You’ll need to be careful on the first part of the descent towards the Baisse de Valmasque (rated T3). From the Baisse de Valmasque, the return journey follows the classic route that runs alongside the Lacs du Basto, Noir and Vert.
