The Valley of the Kikbeek Spring is a nature reserve of 120 hectares located in and around a former sand and gravel quarry in Maasmechelen, where springs feed a water pool, which then nourishes the Kikbeek and flows into the Maas River.
The valley is part of the hiking area of the Hoge Kempen National Park – Mechelse Heide.
The 3 km green walking loop takes you through the old sand quarry and heathland landscapes.
