Grenspark
Kalmthoutse Heide

Enjoy nature without borders in Grenspark Kalmthoutse Heide! This diverse and dynamic nature reserve straddles both sides of the Belgian-Dutch border and consists of heathland, fens, woods and dunes.
Experience the park

Two countries, one natural environment

That nature does not think or grow in boundaries is clear in Grenspark Kalmthoutse Heide. This nature reserve lies on both sides of the Belgian-Dutch border and covers about 60km². Yet the area feels borderless, endless. This is due perhaps to the great diversity in the landscape.

Among other things, the enormous diversity of this piece of nature is of considerable ecological and cultural-historical value. Here, vast, untouched landscapes of heathland, fens, dunes, forests, meadows and polder alternate. Here, many visitors catch their breath, literally and figuratively, on foot, by bicycle, mountain bike or on horseback. Here, rare plants and animals live in peace and quiet. Here, in short, so much life finds the peace and fertile soil it needs to survive. No wonder, then, that Grenspark Kalmthoutse Heide is part of the Natura 2000 network that protects the most important nature reserves throughout Europe in a sustainable way.
