Kalmthoutse Heide

National Park in Antwerp

Kalmthoutse Heide is one of the most striking natural landscapes in northern Belgium, stretching across the Flemish Region and into the Netherlands. Just an hour from Antwerp or Lier by train and bus, this vast cross-border reserve is known for its wide heathlands, pine forests, and tranquil pools. The terrain is open and ever-changing, with seasonal colours transforming the scenery—especially in late summer when the heather blooms into a soft purple haze. It’s a perfect destination for walkers, cyclists, and nature lovers looking to escape the city and immerse themselves in a peaceful, uncrowded environment.

The area offers a well-marked network of hiking and cycling routes, ranging from short loops to more ambitious treks. Trails lead you past mirror-like lakes such as the Stappersven, where birdwatchers gather with binoculars and cameras. Wooden observation towers offer panoramic views across the heath, and in some places, elevated walkways help protect fragile habitats while providing easy access. Kalmthoutse Heide’s flat trails make it suitable for families, while the diversity of its landscapes ensures plenty of interest for seasoned hikers. Interpretive panels along the way help you learn more about the flora, fauna, and geological history of the region.

One of the park’s standout features is the nearby Arboretum Kalmthout, just minutes from the main entrances. This botanical garden houses one of Europe’s most diverse plant collections and is particularly beautiful in spring and early autumn. There’s also a visitor centre on the Belgian side of the park, where you can pick up maps, rent bikes, or join guided tours. Whether you’re drawn by photography, quiet contemplation, or the chance to spot rare birds, Kalmthoutse Heide offers a refreshing blend of natural beauty and outdoor activity—ideal for a full day of exploring or a peaceful afternoon close to nature.
