Mercantour National Park is a mosaic of natural environments which explains the richness of its fauna (not far from 9000 species, such as marmots, mouflons, golden eagles, grey wolves, amphibians. ) and its flora (2067 plant species including edelweiss, genepi blanc, arnica, gentian...): the immediate proximity of the Mediterranean ensures ideal conditions for their existence.
The Mercantour is also characterized by its historical heritage. Dating from prehistoric times, the Valley of Wonders takes its name from the thousands of engravings on coloured stone slabs, the "ciappe", which decipher scenes of daily life and belief. It is characterized by its mineral and chaotic landscape, at the feet of imposing peaks.

BOREON - PAS DE MAIRIS - LA MADONNE DE FENESTRE
After the destructive storm of 2019, this particularly affected village compared to the rest of the Mercantour (no visible traces of damage on the rest of your route) is rebuilt with force... Facing the Alpha Park (interesting to visit if you arrive the day before), you climb in a remarkable conifer forest towards the Pas and the small refuge of Maïris to reach the Cime du Pisset. A panoramic view of the Vésubie opens up to you with, in the background, the famous Gelas, a stone colossus proudly dominating these remote valleys of the Alpes Maritimes. Descent on the hospices of the Madonna de Fenestre where you spend the night, without luggage transport.
5h00 walk / Altitude difference: +845 m; -400 m / 8.5 km
LA MADONNE DE FENESTRE - PAS DU MONT COULOMB - SAINT GRATS
Leaving from the Madonna, do not hesitate to stop at the Petite Vacherie, at the edge of the torrent, to buy a piece of tomme for your picnic, it is delicious (open when the herds are in the alpine pasture). You go up the torrent of the Vésubie which takes its source on the foothills of the Gelas (3143 m) and you contemplate during all your ascent, the Pas du Mont Coulomb. The Pas du Mont Coulomb (2548 m) is characterized by a narrow gap forming a "secret passage" between the Vésubie and the Gordolasque. During your rapid descent on the Gordolasque, you are probably watched by herds of ibex or chamois in the surrounding bars! Descent on one of the accommodations of Saint-Grats.
5h walk / Altitude difference: -700 m ; -1050 m / 11.5km
SAINT GRAT- PAS DE L'ARPETTE - REFUGE DES MERVEILLES
Departing directly from Saint-Grat, you climb in a dense forest to reach the remarkable valley of Empuonrame. It is in this mineral universe that you finish the climb to the Pas de l'Arpette (2351 m), under the watchful eyes of the chamois. The Pas de l'Arpette is the entrance to the Mercantour National Park and the famous Vallée des Merveilles. Descent in the middle of many lakes to the refuge des Merveilles, without luggage transport.
5h00 walk / Altitude difference : +950 m; -410 m / 8 km
REFUGE DES MERVEILLES - VALLEE DES MERVEILLES - BAISSE BASTO
A long and busy day visiting where you have to leave early! From the Refuge des Merveilles, you go up the famous valley of the same name… In the middle of this mineral landscape sculpted by melting glaciers more than 10,000 years ago, lies an archaeological treasure of about 40,000 rock engravings mostly dated to around 3,300 BC. You join the Baisse de la Valmasque (2552 m), the Basto lake and the Baisse Basto (2693 m), a narrow passage in a scree overlooking the Fous valley. Descent by the famous GR52 to the beautiful restored refuge of Nice where a break on the terrace of Christophe will be well deserved. Another 1h30 of descent in the Gordolasque valley to reach your accommodation
