A short loop for everyone to enjoy and discover the marmots and their environment at the foot of the beautiful site of the Mont-Dauphin stronghold.

The trail starts at the marmots site and follows a tarmacked road before branching off to the right to reach a marked dirt trail. You can see the marmots’ burrows from afar. If you stay far enough away, you will easily observe them eat, play, run or sunbathe on the rocks. CAUTION: do not feed them (it is a threat to their health), this mammal finds all it needs in its natural surroundings. You will find panels telling you all about this exceptional natural site, classified as Natura 2000 for its environmental value (steppe-like ecosystem of the Durance). You are at the foot of the ramparts of Mont-Dauphin, whose rock faces have climbing routes. You can descend from here by the tarmacked part of the road closed to vehicles, up to the starting point carpark. There is a view of the modern part of the village of Eygliers, the Durance valley and the summits of the Écrins mountains, including the Pelvoux and its peak at 3.946 m.

On the way...
Chapel of St. Guillaume

The chapel of St. Guillaume is closed to the public but it is the Legend of St Guillaume that is of most interest. For centuries, the miraculous hand of Saint Guillaume has been the object of pilgrimages and prayers, so on the only day of the year that the chapel is open - Easter Monday - do not miss the procession that brings the hand of St. Guillaume in a casket to the chapel. The local tradition is then to tap hard-boiled eggs, whoever’s egg cracks first has to buy the next round!

Lunette d'arçon

In 1700 Vauban had already recommended the construction of three advanced defensive elements. The first half-moon was built between 1728 and 1731, but the other two were never constructed. The building was then modified following orders from General Arçon in 1792 with the addition of a tower connected to the main fort by an underground tunnel.
