This part of the trail follows a shale depression (the Belvaux syncline) and on your left, to the south, the land rises to the limestone massif of Bois de Niau. The relief here is thus directly dictated by the nature of the subsoil. The shales found at Belvaux and throughout the Famenne are very soft and friable (subject to the action of frost, roots and groundwater) and lie in a depression. After 1.5 km you will find on your left a dirt path across the fields. The entrance to this path is signposted “Ruines de l’Ermitage”. At the far side of the field, turn right uphill to the Bois de Niau (keep following the signs for “Ruines de l’Ermitage”).
