ウペイエの峡谷・トップ8

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!

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.

Wonderful single track with deliciously scented wild garlic on both sides.

Text board [see photo] Gravel pit Savelsbos Geological monument 'Gravel pit Savelsbos'. From Roman times until around 1950, a mixture of sand and gravel was excavated in this pit to improve and harden roads. Around 1 million years ago, the Maas flowed from Eijsden towards Cadier en Keer. At the end of this period, the Maas valley was filled with a mixture of sand and gravel. The sand, gravel and stones present come from the Vosges and the Ardennes.

Between the small houses, where the roof is almost in the mountain, there is an entrance to the corridors of a cave, which may only be entered with guidance...

If entry is prohibited, I'd better stay away and enjoy the outside...
