Thorpark Trail
Start


Start: Thorpark Gateway
This walking adventure begins at Thorpark, one of the nine gateways to Hoge Kempen National Park. The Waterschei Coal Mine once stood here. As you walk, you’ll not only enjoy beautiful landscapes but also discover the rich mining heritage of this region. You can explore this history in a high-tech way at Thor Central. The immersive film Thor Experience and the Thor app, featuring virtual and augmented reality, take you on a journey through past, present, and future.
Start: Thorpark Gateway - André Dumontlaan 67 - 3600 Genk
Insider tip!
Curious about daily life and work in the mines? At the nearby Mijndepot, former miners share their personal stories.
The Waterschei Coal Mine
The Waterschei coal mine operated for 63 years, from 1924 to 1987. At its peak, more than 3,800 people worked here. Altogether they extracted 72 million tonnes of coal from deep underground – in some cases as much as 1,200 metres below the surface.
The Waterschei Schans
The Waterschei Schans goes back much further in time, to the late 17th century. At that time local villagers were granted the right to build “schansen” – fortified refuges where they could hide from roaming bands or marauding soldiers. The Waterschei Schans was extensively reconstructed in 1980. Since 2017, it has been part of Schansbroek neighbourhood park, within the Stiemerbeek Valley.
Stiemerbeek and Bosbeek Valley
The valley of the Stiemerbeek and Bosbeek streams is another scenic highlight. This spacious walking area is crossed by the imaginary divide between the Meuse and Scheldt river basins. In the south, rainwater and groundwater flow via the Stiemerbeek into De Wijers, often called the land of 1,001 ponds, before eventually reaching the Scheldt River. In the north, the Bosbeek carries water towards the Meuse River. Today, the valleys of these two streams offer a beautiful setting for a walk. Atmospheric wooden boardwalks guide you through the landscape.
The Waterschei Spoil Heap
Following the former railway line known as the Kolenspoor, you enter a completely different landscape. This is where the climb up the first spoil heap of the day begins. These distinctive hills were created from mining debris. When material was brought up from the mines, the coal was separated and used, while the remaining stones were piled up into large mine-stone mountains. The Waterschei spoil heap has two summits: The northern cone remained untouched after the mine closed and became naturally overgrown. On the southern summit, grass and flowers were deliberately sown.
Insider tip!
Take a short detour from the trail and climb all the way to the top of the spoil heap. You’ll be rewarded with a spectacular 360° view over Hoge Kempen National Park.
Juniper Berries in Heiderbos
Heiderbos provides a refreshing change of scenery along the trail. More than 7,000 juniper bushes grow here across several dozen hectares. Their bluish-green fruits turn black when ripe and resemble berries. Elsewhere, these berries are used as a key ingredient in Jenever, a regional speciality spirit.
The ring oaks of Klaverberg and the Opglabbekerzavel Heath
At Klaverberg, you’ll encounter a remarkable natural phenomenon: a ring of oak trees These trees grow in a circular formation, sprouting from the roots of a dead or cut main trunk. When this process repeats itself over time, the circle of trees gradually becomes larger. After passing these unusual trees, continue across the inland dune known as Klaverberg. Nearby, you’ll also find parts of the unique Opglabbekerzavel, a distinctive heath landscape.

Finish: Thorpark Gateway – Waterschei Coal Mine
About 16 kilometres later, you’ll finish where you started. The hike ends back at the Thorpark gateway, where another highlight awaits; Lichtsporen, an installation by Daan Roosegaarde nestled among the trees. This artwork symbolically connects the region’s mining past with a future focused on energy, technology and connectivity. It is particularly spectacular after sunset.
