Most of Wallonia's better known birding spots for waterfowl (and reedbed associated birds) are in the west, but this is one of the best known spots to the east. Good visibility on all the ponds and a beautiful new lookout cabin built a couple of years ago. A common haunt of the Bearded Tit, Bluethroat, Eurasian Hobby and Water Rail among many others. Also a relatively important spot for the more common waterfowl such as the Common Teal, Northern Shoveler, or Eurasian Moorhen. An oasis of diversity in the middle of intensive farmland activity.



Just a few minutes off the A3 motorway at the 28A exit, next to the town of Hollogne-Sur-Geer. Free parking spaces are available coming from the west through the fields (rue des prés) or from the east in the middle of town (rue du centre). The location can be visited on foot.

Note: At the moment there is a sign that says: 'Closed due to visitor misconduct... until July 15, 2021'
