Northeast of Muno, Roche à l'Appel, located in the Roches valley, offers an exceptional site for botanists and geologists. It contains rare combinations of lichens, mosses, and ferns, as well as an impressive rock bank composed of a conglomerate that formed the base of the great seamount covering the Cambrian bedrock. This conglomerate, known as Fépin (or Linchamps), consists of sandstone and quartzite blocks of varying sizes (up to about 50 cm in diameter) and angular to rounded shapes, scattered within a finer, clayey, sandy matrix.

Magnificent estate of 1721 hectares Located north of Lacuisine and west of Chiny, it belongs to the CPAS of the city of Mons, which inherited it in 1887. This sublime estate includes 1,500 hectares of forests and four artificial ponds fed by several streams, including the Tamij-Austria, a tributary of the Semois. The ponds of the Epioux are the last witnesses of the important metallurgical past of our region. Indeed, for more than three centuries, the estate experienced intense metallurgical activity. Since the end of this industrial activity, the only profitable economic activity has been that of forest production. Today, the large forest of the Epioux is a magnificent forest. Several beautiful walks cross the estate.

Beautiful views as pitting but great path for walking... for me the pieces are asphalt... "roads where cars drive" sometimes a shame for the rest. Really a winner.👌

A mythical, sacred place of our distant ancestors. The Dolmen can be reached with some scrambling. Caution is advised because one misstep and you end up in the realm of our distant ancestors.

The reward is worth the effort, as you will enjoy breathtaking views and a feeling of accomplishment.
