Mercantour - Hut-to-Hut

As soon as you leave the cozy Refuge de Nice behind, you descend towards the Vallon de la Fous. Once on the other side of the valley, you’ll face a climb over impressive glacier-polished rocks, which will lead you to the idyllic Lac Niré, situated at 2,353 meters. This tranquil mountain lake is the perfect spot for a short break.

From the lake, you continue north along the right bank of the Chamineye Valley. Along the way, you’ll pass three picturesque small lakes, also known as "lagarots," beautifully located at the foot of the imposing north face of La Tête du Lac Autier.

After crossing the valley, you reach an area of scree and begin the ascent to La Baisse du Basto (2,693 meters). The climb is steep and about 250 meters, so again, take your time walking up. The final climb takes you through a narrow rocky passage, worn down by the many adventurous hikers before you. Early in the season, snowfields may still be present, so proceed with caution.

From La Baisse, the route continues along the GR52 through a breathtaking landscape of vast alpine meadows. The descent begins after passing a small lake on your left. The path leads you to the impressive Lac du Basto, a true gem in the rugged landscape.

Turn left here and enjoy a scenic hike along three stunning lakes: first Lac du Basto, then Le Lac Noir, and finally Le Lac Vert. At the shore of the last lake lies your destination, Refuge de la Valmasque, the perfect place for a well-deserved rest after this beautiful hike.

Today's hike begins by heading back towards Lac de Basto. As soon as you arrive here, you’ll quickly begin the climb towards today’s mountain pass. Fortunately, the summit isn’t very high today, which is a relief after the hikes of the past few days. From here, you will continue on the GR52 and soon reach the Baisse de Valmasque at an altitude of 2549 meters. Take a moment to look around and enjoy the stunning views of the lakes in the Vallée des Merveilles. From this point, you will zigzag your way down, passing through the Vallée des Merveilles. Along the way, you will encounter several beautiful mountain lakes and have the opportunity to admire magnificent rock engravings. For thrill-seekers without a fear of heights, the climb up Mont Bégo (2873 meters) is well worth the effort.

The destination for today is the Refuge des Merveilles. This hut is located on the shores of Lac Long Supérieur, in the heart of the Vallée des Merveilles. Nestled between Mont Bégo and Devil's Peak, this area is steeped in history, with tens of thousands of rock carvings to admire at an altitude of over 2000 meters.

Today’s goal is to reach Pont des Sagnes. This route is less crowded than the classic path many hikers take toward Pont du Countet, but it’s no less stunning. Explore the rugged Vallon des Verrariers, and if you’re feeling adventurous, climb the Cime du Diable (Devil’s Peak) at an altitude of 2685 meters.

After leaving the refuge, pass by Lac Fourca, Lac du Trem, and Lac de la Muta, heading towards Pas du Diable. If you have the time and energy, ascend to the summit of Devil’s Peak. From its stunning viewpoint, you’ll enjoy a 360-degree panorama of the Mercantour and l’Authion, and with a keen eye, you can even spot the sea.

Continue toward Vallon des Verrariers, where the hike involves regular rock climbing. The trail here is less defined than on well-marked paths, so keep an eye out for the signs along the way. After traversing the valley, descend 700 meters over approximately 4 kilometers to arrive at Pont des Sagnes.
