Description of the route

From Piazza IV Novembre in Pont-Saint-Martin, cross the Lys and go up the mule track that bends to the left, passes under a portico and winds up slightly to the residential area with the antenna tower. When you get to the regional road of Gressoney valley and the itineraries just a few metres away towards the left, take the right-hand track that leads off the road that goes to the hamlet of Ivery. Stay on this track for just a few minutes. Get back onto the mule track, which breaks off to the left, then, take the old road to reach Ivery. Continue along the road and, after a left bend, continue along a flat section of the mule track which takes you to an aqueduct construction. The itinerary now continues upwards and leads to the plateau where the Holey pond natural reserve is located. Take the small road on the right near the houses, which leads to the paved road at the foot of the promontory on which can be found the remains of Suzey castle. Continue along the road towards the left until you come to a small group of houses, then take an farm track on the right, then leave it to take the path on the left which goes up to the ruins.
