Along a country road with hedges and narrow forest paths to Vaux-sous-Olne

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

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!

Picturesque Chefna valley. One of those beautiful streams here, originating on the plateau of the Parc Naturel des Sources. The steep drop and rocky bottom make it unique. The water cascades over the boulders in waterfalls and pools. It flows gently now (July), but it will be raging in the rainy season.

Unexpected spot in the middle of the park, next to a viewpoint over the city (let's see if we can still see that far when the trees have turned green...), a reminder of a time when the walking routes were punctuated by https://www.dogwhistlings.com

Impressive, you can see some caves.

The mechanical erosion of the fast, swirling waters created deep, narrow hollows that connect the pools. These pools were given poetic names such as "Bain du Cerf" (Deer Bath), "Bain de Diane" (Diana Bath), "Bouillon de la Chaudière" (Cauldron Bubbles), "Bain des Naïades" (Water Nymphs Bath), "Bain de Vénus" (Venus Bath), "Bain de la Loutre" (Otter Bath), "Bain d'Hermès" (Hermes Bath)
