A short but exceptional walk in the Ardenne et Gaume nature reserve with its magnificent geological rock formation Roche à l'Appel. Hikers must have a good condition to cope with the winding, sometimes quite steep paths. The circuit on and around the Roche à l'Appel is very special.

Geological walk at Muno.
The Roche à l'Appel was created by geological fractures at the level of the cutting surface of the primary massifs and the so-called basin of Paris. Pebbles, rock debris and quartzite from the Cambrian were crushed here 400 million years ago and form mysterious formations that are also highly appreciated by mountaineers. From the top you have a view of the mixed beech and oak forest, where mosses, lichens, heather and black blueberries grow.
Sturdy walking shoes with a good grip.
Appropriate clothing and picnic.
Caution is advised on the rocks in wet weather.
