Dunbergbroek (Hagelandse Vallei)

Dunbergbroek is one of the core areas of the Hagelandse Vallei — the richest and ecologically most varied valley in the entire Hageland region, in the Belgian province of Flemish Brabant. It stretches along the Winge river valley within the municipality of Holsbeek, forming a single connected nature complex together with Kloosterbroekbos and Horst, managed by the conservation organization Natuurpunt.

What makes this valley special?

Water shapes everything here. Very pure groundwater flows out from the base of the surrounding Hageland hills, keeping large parts of the Winge and Motte valleys permanently and naturally waterlogged. That is unusual for this part of Flanders, where most comparable wetlands were drained for agriculture long ago. As a result, Dunbergbroek remains a wet, quiet landscape of hay meadows and marshland where the sounds of nature dominate rather than traffic or buildings.

How is the area managed?

The hay meadows in Dunbergbroek are mown once or twice a year, and a flock of Friesian dairy sheep handles the aftergrazing. This is a classic active-conservation approach used by Natuurpunt: without regular mowing and grazing, wet meadows would quickly be overtaken by reeds and scrub, losing the ecological value that makes them worth protecting.

What wildlife can be found here?

The mosaic of wet meadows, reedbeds, and woodland patches supports a rich variety of species. Buzzards, polecats, kingfishers, and deer all thrive in this landscape. In spring and summer the wet meadows come alive with plants typical of this habitat, including marsh marigold, broad-leaved and spotted orchids, and small valerian.

How can you plan a visit?

Dunbergbroek forms part of the Hagelandse Heuvels walking network, which totals more than 300 km of trails. A popular route is the Dutselhoekwandeling, a 6.8 km walk that starts at the church in the center of Holsbeek and follows narrow, quiet paths straight into the heart of Dunbergbroek. From there the trail climbs toward Chartreuzenbos, a forest dominated by oak, birch, and beech, offering views over the Dunbergbroek and Winge valley along the way.

The easiest access point is via Molenbaan in Wezemaal (3111). The area is also regularly visited as part of organized nature outings — Natuurpunt and the municipality of Holsbeek run themed walks here, such as herb walks where guides point out wild meadow plants and explain their traditional uses.
