Mechelse Heide, Natural reserve in Maasmechelen, Belgium.

Mechelse Heide is a nature reserve between As and Mechelen-aan-Maas, about 700 ha on the eastern edge of the Kempens Plateau. Its centre is a large heath field with purple and red heather and three broom species, mixed with coniferous woods. The soil is loamy sand with peat here and there. A single slender tree rises above the tall dry grasses of the open heath.

Mechelse Heide was recognised as a nature reserve in 1967 and is managed by the Agency for Nature and Forests. Around 2000 the tourist road that ran straight through the heath was closed to motorised traffic and turned into a cycle path. The area forms part of the Hoge Kempen National Park and is protected as Natura 2000 habitat and bird area. Since 2021 the adjoining Mechelse Heide Noord has been laid out with walking routes and a cycle path.

The purple colour of the blooming heather returns in the logo of the Mechelse Heide access gate, a purple footprint. At the gate on the Joseph Smeetslaan, near campsite De Salamander, stand an information shelter with a map, a picnic meadow and a cafeteria. The Beestige Boelbos, 500 metres from the shelter, introduces children playfully to local animals.

Entrance is free and the site is open year-round, with parking available at multiple entry points. The marked trails are easy to follow and accommodate different fitness levels, making visits flexible.

In the final weeks of summer, the entire heathland turns purple as millions of heather plants bloom simultaneously, transforming the landscape into a carpet of color. This spectacular flowering draws many visitors who want to experience this memorable seasonal shift.
