Cime de la Costette walks

The most difficult stage of thisGR®, but the most beautiful for its landscapes, flora and fauna: chamois, marmots, ibex. After the Pas des Ladres, we chose to take theGR®52via the alternative route that passes close to the Col de Fenestre, then descends to Lac de Fenestre before reaching La Madone de Fenestre. Three sections are particularly difficult: between Lac de Trecolpas and the Pas des Ladres, the ascent of the Pas du Colomb, and the descent from the Pas du Colomb.

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 GR®52 starts in Saint-Dalmas de Valdeblore. This first stage is a transition to reach the starting point of the GR®.This is a lovely hike that passes through the small resort of La Colmiane and offers a relatively easy climb, following the GR®52 A through the woods for just over 6km.

Second stage of the route and first stage on theGR®52. A long 21km stage taking in the Col de Veillos, numerous lakes, the Col du Barn, the Vacherie du Collet and the Col de Salèse, ending at a place called Le Boréon. A spectacular stage thanks to its landscapes and views, but very difficult.

Route linking the Vésubie and Gordolasque valleys.

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 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 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!
