The park's soil composition includes shifting dunes formed during the post-glacial period by wind-blown sand.
It is a transboundary park, meaning it is managed by both Belgian and Dutch authorities.
The heathland is home to the rare sundew, a carnivorous plant that thrives in the nutrient-poor, waterlogged fens.
Fire management is critical here; the dry sandy soil and heather make the area highly susceptible to wildfires, leading to the use of specialized lookout towers.
The park contains archaeological remnants of burial mounds dating back to the Bronze and Iron Ages.
Grenspark Kalmthoutse Heide is one of the oldest nature reserves in Belgium, spanning approximately 3,750 hectares across the border of Belgium and the Netherlands. The landscape is characterized by shifting inland dunes, nutrient-poor fens, and extensive dry and wet heathland. It serves as a critical habitat for rare species, including the northern crested newt and the moor frog. The park features over 25 signposted hiking routes, ranging from short loops to longer cross-border trails. Several elevated observation towers are installed throughout the park to provide panoramic views of the varied terrain. The area is maintained through controlled grazing and vegetation management to prevent the encroachment of forest into the heath. Visitors can access the De Vroente visitor center, which serves as a central hub for information and educational exhibitions. The terrain is relatively flat, making it accessible for varied fitness levels. The park is part of the Natura 2000 network, emphasizing its ecological importance within Europe.

Follow the marked wooden posts to avoid trampling sensitive vegetation and disturbing local wildlife.
Stepping off the marked trails, as the sandy soil and rare plants are easily damaged by foot traffic.
Access may be restricted during periods of extreme high fire risk, indicated by red flag warnings at park entrances.
Keep dogs on a leash at all times, stay strictly on designated paths, and take all trash with you.
