From the parking lot, you'll immediately walk into open nature. Wide sandy paths will take you to the Drielingvennen, a characteristic fen that forms part of the typical heathland of the Kalmthoutse Heide. These fens are ecologically valuable and provide a habitat for amphibians, dragonflies, and waterfowl. After the fen, the route continues towards the Wilgenduinen. Here, the landscape changes noticeably: rolling sand dunes alternate with heathland and sparse grasslands. These dunes were formed by historical sand drifts. Further on, you'll walk along the Kabuusduinen, one of the most open and rugged areas in the area. From the higher elevations, you'll have expansive views of the heathland and the surrounding forests. During this walk, you'll pass through active grazing areas where large grazers, such as cattle and sheep, are used for nature management. These animals keep the heathland and dunes open and prevent trees and shrubs from taking over the landscape. A unique and lesser-known highlight of the walk is the visit to the remains of the Mont Noir estate. In the 19th century, this area was not a nature reserve, but an ambitious private estate. A Brussels industrialist commissioned the creation of a park with avenues, ponds, and buildings. Later, the estate came into the hands of Bernhard Bernsohn-Stern, a Jewish diamond merchant, who had ambitious plans to transform Mont Noir into a recreational attraction. Attractions were to be built, including a narrow-gauge railway to Heide station. The outbreak of the First World War abruptly ended these plans. The estate fell into disrepair and was eventually reclaimed by nature. Today, only a few columns and landscape structures remain. After Mont Noir, you walk along quiet forest roads back towards Parking Noord. The transition from open heathland to closed forest provides a pleasant change.
