Hiking in Wallonia: the ‘Roche À L’Appel’, a geological trail near Muno

  • Walking or hiking

This superb 3 hours hike will take you through the protected natural area of ‘Ardenne et Gaume’, starting from the ‘Roche à l’Appel’ and its stunning view over the region then passing through through beech and and oak woodlands. You must be reasonably fit to take on the winding paths, featuring some steep cliffs but these 8.5 km are well worth the effort.

A geological walk

Geologists from all over the world come here to marvel at this mass of rock, essentially consisting of puddingstone, formed by the folding of the primitive massif and the Parisian Basin. Gullies, rocky scree and Cambrian quartzite solidified here about 400 million years ago into a natural cement to create their mysterious shapes. From the summit there’s a view over the mixed forest of beech and oak trees, where moss, lichen, heather and blueberries flourish.

Route/Points of Interest

  • From the car park (S) in an old quarry, the trail first heads towards the left (yellow triangles/diamonds signage) in the direction of Roche à l’Appel (wooden panel).
  • Along a wide forest track you soon come to a little stone bridge (1) that spans a stream to open out into a rest area (2) at the foot of the Roche à l’Appel.
  • Climb from there, following the waymarkers (yellow diamond No 6) on a twisting, steep track over the rock formation. At the top you will find a bench from where you have a fantastic view (3).
  • The trail continues on a beautiful little path passing different viewpoints before going back into the forest.
  • The trail continues to descend (occasional signs on your right). A little lower the path divides. You must take the right fork and follow the yellow diamond signs (No 6). If you continue to descend along the path you will reach an old quarry with a barbecue and rest area. Behind the quarry, stay on the main trail.
  • At the crossing, turn left and keep going straight ahead following the green triangles.
  • At the following Y-junction, go right (green triangle No 7). The route keeps parallel to the RAVeL before turning left at a stream, crossing several small watercourses.
  • At a very large crossing, take the furthest right of two tracks, turning sharply to the left, while staying on the main track (note that there are no signs at this point!) Here the trail becomes very narrow and sinks into a dense mixed forest.
  • At the end of this truly wild section, you will come to another large crossing. Take the main stony forest track running to the left (wooden panel: ‘Muno’; green triangle signs).
  • After a long downhill section on the track (about 2 km), after a bend to the left you will come to a fork. Attention! Turn sharp right and follow the other set of signs (yellow triangle No 5 is visible a little further on, to your right) as you climb.
  • The forest track leads to a fork level with a stream (‘Gué du Roy) that you can cross on a small metal bridge (4).
  • Then descend to the left.
  • After a few minutes, you return to the stone bridge with the rest area, under the Roche à l’Appel. The signs with yellow triangles lead you back to the car park.

Prepare your walk

Make sure you wear good hiking boots and comfortable walking clothes. In case of rain or frost, please be careful on the rocks which can be slippery.

There is no café along the road so take some snacks and water with you.

Author’s Tips

The circuit includes a delightful detour to Florenville or the Trappist abbey of Orval, which brews the famous beer of the same name.

In the downloadable brochure below, we have selected one of the best walks per province: natural gems, family friendly paths, memorable views along the way, trails sprinkled with history… One even will introduce you to the iconic abbey beers.

A walker's guide to Wallonia

If you were to draw a straight line on an atlas northward from the Massif Central in France to the North Pole, the only area of high ground the line crosses is the Ardennes, shared between Belgium, Luxembourg and Germany – but mainly belonging to Wallonia, the southern part of Belgium!
