There are old flint quarries in this area: the “Carrières de silex du Thier des Vignes”.

A delightful path in the Ruisseau du Blanc Gravier valley. It alternates between a forest path and a stream. It connects the pond with the Quartier Blanc Gravier.

A mysterious flint cave on the edge of the Albert Canal, near the locks at Klein Ternaaien. You reach the entrance via a steep path through the woods. The caves are dark, cool, and full of atmosphere—perfect for those who love hidden natural spaces. Bring a flashlight and good walking shoes!
