Beautiful sand dunes with heather, relatively small but well worth it. A highlight of our walk.

The ideal time to enjoy beautiful colours is certainly the month of September when the heathers are in bloom.

The heathland on the Oudsbergduin is one of the most impressive, yet also most fragile, nature reserves in the Hoge Kempen National Park. This unique dune area, located between Oudsbergen (Opglabbeek) and Gruitrode, is no ordinary heathland: here you walk across a rare inland dune landscape that formed after the last ice age and is today one of the largest drifting sand complexes in Flanders. 🌬️ Landscape shaped by wind and time The Oudsberg formed thousands of years ago when meltwater and strong winds pushed sand from dried-up riverbeds into high dunes. Centuries of grazing and deforestation left the sand partially exposed, resulting in a dynamic landscape of: • undulating sand plains • vast purple heathlands • juniper bushes and sparse grasslands • pine forests on the edges The result is a remarkable panorama that is constantly changing under the influence of wind, seasons, and management.

Oudsberg, along with Solterheide and Donderslag, is part of a long dune belt. The area promotes itself as the "Dune Belt." The dune belt is a 3,000-hectare, diverse, and extensive heath and forest landscape.
