When I was young, I used to climb from the bottom of the cave and we would reach the very top of the site. With a beautiful panorama of the city.

It's a very beautiful place for a walk. You can start from the Trixhes, go down a small path along the quarry. When you get to the bottom, you arrive at the Carrière des Roches. From there, you pass by two sides with different rocks. If you continue, you arrive in "Houlbouse" street. And finally, at Chokier. Very beautiful hike. To do with dogs and especially children.

The gravel pit is a very rich site for photo enthusiasts or for walkers who wish to walk on maintained paths and observe birds in complete tranquility. Site recommended for walkers and photographers. Please, can you respect the rules such as keeping your dog on a leash (even if some people think they won't do any harm by letting their dog off the leash, know that you have animals with predator instincts which could scare away some species of birds that nest on the ground, like the kingfisher) and not swimming so as not to disturb the birds that are there. Thank you to all those who will respect the rules and I wish you a good hike or a good photo outing 🙏.

A beautiful area of (only) 34.5 hectares, characterized by reed beds, cattail ponds, and pools fringed by shrubs or with open banks... These diverse habitats offer countless bird species places to forage, nest, hibernate, or rest during their migration. No fewer than 212 species have already been observed! (Source: www.natagora.be)

Deciduous forest traversed by the Hornebeek stream. In recent decades, it has dried out considerably, especially during the summer, with the stream also drying up because the Water Group operates a drinking water extraction facility here. This permit is expiring so the stream and wet forest can slowly recover.

Through the Hornebos forest of deciduous trees and shrubs. Nature management here means "leave everything that falls or blows over." The Hornebeek stream accompanies you along the avenue. The first source immediately runs to the left of the road, while the second source emerges 200m from the right, passing under the road, where they continue together.

The marl caves of Heers are an important hibernation site for numerous bats, including the Bechstein's bat, the Notched Bat, and the Pond Bat. Bat-friendly barriers were installed at the entrances to the caves. In 2014, the Waterkuil was closed off with a steel gate, in which bat silhouettes serve as flight openings. This elegant barrier was designed by Heers artist Frans Vandueren. Initial winter counts already showed that the gate is having an effect.
