Departure : Eygliers Gare → Arrival : Eygliers Gare

Walk up to Mont-Dauphin through the forest to reach the foot of the first fortified elements. Take your time to visit the Stronghold and the village inside (this is a UNESCO World Heritage classified site). With this itinerary, you can reach and visit the village of Eygliers - Chef-Lieu. The descent via the marmot trail will give you the possibility to observe this mammal.

The trail starts at the “marmots” site and follows a tarmacked road before branching off sharply to the right to reach a trail along a former canal up to a triangular junction. Take the trail going up to the left to reach the RD 137. Leave the road and follow the steep trail to the left (take the steps in front of you). Walk along the cliff to see the fortifications (be careful not to take the trails leading to the climbing sites). You will get to flat ground. From here, follow the trail to the right on the edge of the ramparts to reach a first carpark (bus park). Go on until the lunette d'Arçon and continue towards the carpark. You will have a view overlooking the Guil and find an orientation table. If you look up, you will see the village of Eygliers Chef-Lieu and its church. Go on to the village. To go back, take the same itinerary from the village of Eygliers. When you reach the bus park in Mont-Dauphin (not the one for cars), take the trail going through the pines at the other end of the carpark (indicated with a yellow PR sign). The trail has large curves and leads to fields. Go down to the left at the junction and follow the trail to the marmots site.


For a panorama option, cross the road towards the lunette d'Arçon (fortified element). Turn right to take the trench made for attacks. Then, walk alongside the rockface up to the plateau that gives you an exceptional view of the gorges of the Guil.

From Guillestre, link up to the N94 towards "Briançon". At the roundabout of the N94, turn right to Eygliers station. Park your car on the carpark to the right a few metres from there.

On the way...
Saint-Antoine Church

This simple Romanesque church is the parish church for the inhabitants of Mont Dauphin fortress. A beautiful porch enhances its simple facade, with pink marble columns and smoothed flagstone floors. Look out for the two animal heads carved on one of the doors and inside, rare 16th century paintings discovered in 1968.

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.
