This area, located between the Maas and the villages of Groeningen and Vortum - Mullen, is home to shifting sand that drifted from the dry Maas bed at the end of the Ice Age. The vegetation has since held the sand and created hills. Today, the ‘hills’ are more like humps in the landscape. At the end of the 1950s, the hills became a haven for badgers and other wildlife, and a total of 19 badger setts were identified.
The Groeningse Bergjes are part of the Duvelsklökske experience route. The sound of the bells could be heard from one of the hills.
