One of the largest dry and wet heath areas in Western Europe, straddling the Belgian-Dutch border with pools, juniper and pine woods.
The Kalmthoutse Heide, at 2920 Kalmthout in Antwerp province, is one of the largest dry and wet heath areas in Western Europe and straddles the Belgian-Dutch border. The heath is managed by Natuur en Bos together with partner organisations, and the public paths are free to walk without a permit. The nearest rail link is Kalmthout station, from which the heath edge lies roughly 2 to 3 km away, a distance usually covered on foot or by bike. Drivers can use car parks near the heath entrances, which can fill on sunny weekends.
Waymarked loops cover about 5 to 14 km and take between one and a half and four hours. The terrain is flat and sandy, with essentially no climbing, so difficulty is low, although soft sand makes progress slower than the distance suggests. Surfaces range from loose sand and compacted tracks to forest paths and occasional wet ground beside pools. Exposure is high on the open heath, with wind and sun unbroken, while pine woods and juniper stands provide patchy shade.
Landmarks along the routes include open expanses of heather, small heathland pools known as vennen, groves of juniper, scattered pine woods and old dune ridges. Shorter loops stay close to the heath edge near the entrance, while longer routes cut deeper toward the border area, where the landscape feels remote. A reasonable turn-around point for a shorter outing is the first large pool, which offers views across the heath and a sense of its scale. The heather flowers purple from late July into September, and May and June bring fresh growth and bird activity.
No mountain huts exist, but cafés and refreshments are found in Kalmthout village and near some heath entrances. Visitors should carry their own water. Ticks are a notable risk in heather and long grass, so a check after the walk is advisable. Fire risk can lead to temporary restrictions in very dry summers, and visitors are asked to stay on marked paths and keep dogs on a leash.
