With the Attert, river that gave it its name, the Park presents varied landscapes, with rich fauna and flora. From sand quarries restored as natural reserves to marshes, the Park offers many walks, on foot or by bike to discover these rich environments.


The Park has in particular on its territory the village of Nobressart, one of the most beautiful of Wallonia. Blending built and natural heritage, forest and meadows, the Park offers a palette to suit all tastes.

200 million years ago, during the secondary era, a teeming sea of ​​life covered the entire region. On several occasions, this sea deposited layers of sand, clay and limestone. In these layers of ground, we find today traces of this marine life and shores in the form of fossils. The territory of the Park is marked by this marine period and several quarries punctuate it, in which we find different fossils (gryphées, ammonites ...)


The Park symbol represents an ammonite, a marine cephalopod that roamed this region at that time.
