The Waterschei spoil heap is one of the most striking remnants of coal mining in Belgian Limburg, located in the Waterschei district of Genk. The spoil heap originated as a waste heap from coal mining – during coal mining, rock material that did not contain usable coal was brought to the surface and piled up into an artificial hill. These centuries-old spoil heaps have since become visible landmarks in the landscape and are now deeply rooted in the region's culture and nature. The former mining area around Waterschei was active between 1924 and 1987 and played a significant role in the economic development of the Kempen coal basin. After the mines closed, the area lost its industrial function, but the spoil heaps remained as immense silent witnesses to that mining past. In 1999, the Waterschei spoil heaps were officially designated a protected landscape, emphasizing the value of these structures, not only historically but also ecologically. Today, the slag heaps are part of Thor Park, a redeveloped nature recreation and heritage area of approximately 30 hectares where industrial history and natural experiences converge. Hiking trails have been laid out around the slag heaps, often marked with small stacked stones—symbolic "cairns"—that invite visitors to climb the slopes and leave their own markings. At the top of the slag heap, you're rewarded with a panoramic view of the former mining site, forest, heathland, and the surrounding landscape. The Waterschei slag heap combines history, nature, and recreation. The hill is not only a monument to the mining industry but also a place where vegetation and biodiversity have developed on the rugged stone. As such, the slag heap offers a fascinating example of how an industrial artifact can transform into an ecologically and recreationally valuable landscape.

The yellow route through the Klaverberg Nature Reserve offers one of the area's most impressive panoramas: a panoramic view of the slag heap and the surrounding ponds, where nature and its industrial past seamlessly blend. From this point, you look out over the green flank of the slag heap, a former spoil heap that was slowly reclaimed by nature after the mine closed. Pines, birches, and hardy heathers have established themselves here in the barren soil and today form a unique landscape that symbolizes the resilience of the Hoge Kempen region. The slag heap rises quietly and massively, a testament to Genk's mining past and the Waterschei coal site. At its foot, the ponds lie like reflective havens in the landscape. The water catches the light and reflects the sky, the trees, and sometimes even the silhouettes of birds flying overhead. Here you'll regularly see ducks, dragonflies, and, with a bit of luck, deer cautiously emerging from the forest edge to drink. The combination of height, openness, and silence makes this view a place where you naturally slow down. It's one of those moments where you not only see but also feel: the space, the history, the transformation from industry to pure nature. Whether you pass by here during a leisurely morning walk or in the warm light of the setting sun, this point on the yellow route is undoubtedly one of the most beautiful stops in Klaverberg. 🌿🌊⛰️

The section between the pebble beach and the small entrance and exit has the best open areas to look across the lake to the slag heaps (especially the twin slag heaps). And here is certainly one of them. Another not-to-be-missed section with beautiful views is here (quiet entry): https://www.komoot.com/nl-nl/highlight/6478110
