Hiking

The centuries-long exploitation of marl in this region has created an impressive network of underground galleries, which have now become one of the most important wintering centers for thousands of bats from all over Western Europe.

Hiking

Because there is little rainfall on average, the sun shines brighter, the slopes are well protected and the calcareous soil is very permeable, we come across very rare plant and animal species on the Montagne Saint-Pierre. These are species that are often of Mediterranean origin, such as the wall lizard, some orchids and many insects.
To preserve this unique biotope of calcareous grassland, it is necessary to regularly clear undergrowth and clear the area. The strong Mergelland sheep then take over the maintenance of these grasslands, where they graze in peace.

Hiking

The Montagne Saint-Pierre is the plateau between the lower valleys of the Geer and the Meuse. The limestone subsoil of this region was formed during the Cretaceous period, a period more than 65 million years old, in a marine environment where animals thrived, as evidenced by the discovery of many fossils, including the famous mosasaur.
Over the centuries, a typical vegetation has gradually settled in this region: limestone grasslands, thanks in particular to the use of the slopes as pastures for sheep and goats.
