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.

This twentieth stage marks the end of the crossing of the Mercantour Massif. From Saint-Dalmas, the GR®5 heads south to climb the steep slope towards the Cime de Colmiane, which it bypasses by heading for the Col du Varaire. It crosses the Bois Noir and reaches the Col des Deux Caïres, then the Caïre Gros. The route follows its ridge and, hugging the hillside, passes beneath Mont Chalancha, La Partissuola and the Cime de la Combe before descending to the small pass of Trous. Before the Col du Fort, the path descends to the Granges de la Brasque, crosses the upper part of the Riou du Figaret valley and arrives at the Col d’Andrion. Cutting across the hairpin bends of the M33, the GR®5 reaches the Col des Fournès and the Col de Gratteloup. Through rocky gaps, it runs alongside the Petit Brec d’Utelle and then the Brec d’Utelle. From there, the path descends towards the Crête de l’Albaréa and reaches the Col du Castel Ginesté. It crosses the slope below the ridges of the Têtes du Sac de Bécasse, Parabosquet and Les Pennes to reach the Utelle community lodge.

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.

This nineteenth stage continues the long traverse of the Mercantour. From the Refuge de Longon, the path descends the Vallon du Longon diagonally across the slope to the hamlet of Rougios, before following the Fracha forest road and then taking a shortcut to the pretty Provençal village of Roure. Via a stony descent, it cuts across the hairpin bends of the M130 and M30 roads and reaches Saint-Sauveur-sur-Tinée, which it passes through before climbing up to the Chapelle Saint-Roch. Running along the hillside, it crosses the Vallon du Romarinier, passes through the hamlet of Roubinastre, crosses the Ravin de l’Esclosé and arrives at Rimplas. The GR®5 descends gently towards the small pass of Ragias and crosses the Vallon Gros, before climbing back up to the ridge on that side of the slope and then skirting the hamlet of La Bolline. From there, it climbs to the hamlet of La Roche and then ascends the ridge of the Vallon de Bramafam to reach Saint-Dalmas Valdeblore.

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.
