The park supports a rich wildlife population, including numerous bird species such as the nightjar, woodlark, and tree pipit. Larger mammals include roe deer and wild boar, while smaller species include the viviparous lizard and various amphibians in the park's wet areas. The heathland provides crucial habitat for many insect species, including rare butterflies like the silver-studded blue and various dragonfly species. The park's diverse ecosystems also support numerous species of spiders and beetles unique to heathland environments.
The park hosts a diverse range of plant species adapted to its sandy, nutrient-poor conditions. The dominant vegetation includes common heather (Calluna vulgaris) and cross-leaved heath (Erica tetralix), which create stunning purple landscapes in late summer. Other notable species include sundews (Drosera), a carnivorous plant found in wet areas, various species of mosses and lichens, and scattered stands of birch and pine trees. The park also contains rare plant communities specific to inland dune systems and wet heath environments.
The park's landscape was primarily formed during the last ice age, characterized by wind-blown sand deposits creating distinctive dune formations. The soil consists mainly of nutrient-poor sand, with some areas containing peat layers formed in wet depressions. The varying ground levels create a diverse landscape of dry dunes, wet heathlands, and fens. The area's unique geological features include active inland dune systems, which continue to shift and evolve through natural processes, making it one of the few remaining dynamic dune landscapes in Western Europe.
The Grenspark De Zoom-Kalmthoutse Heide has been shaped by human activity since medieval times. Originally part of a vast heathland system, it was used for sheep grazing and peat cutting by local communities. In the 19th century, parts were planted with pine forests for timber production. The area became a protected nature reserve in 1950, and in 2001, it was officially designated as a cross-border park between the Netherlands and Belgium, covering approximately 6,000 hectares. The park represents one of the first successful international conservation collaborations in the Benelux region.
Key attractions include the Volksabdij visitor center, offering exhibitions and information about the park's ecology and history. The park features extensive hiking and cycling trails, including the 24-kilometer Grenspark hiking route. Notable landmarks include the Putse Moer lake system, the Tower of Bosduin offering panoramic views, and the historic Ravenhof Castle. The park also contains several observation points for wildlife watching and photography, particularly around the heath and wetland areas. Educational nature trails and guided tours are available, making it an excellent destination for environmental education and nature appreciation.
The park experiences a temperate maritime climate typical of the Netherlands and Belgium. Summers are mild with average temperatures around 20°C (68°F), while winters are cool with temperatures averaging 3°C (37°F). Rainfall is distributed fairly evenly throughout the year, with slightly higher precipitation in autumn and winter months. The best time to visit is between May and September when the heathland blooms and weather conditions are most favorable for outdoor activities. Visitors should be prepared for sudden weather changes and occasional strong winds across the open heathland.
