The sunken road itself is used by the more adventurous and probably younger cycling adventurer, judging by the small sand-jumping hills constructed in it.

The sunken road itself is quite beautiful with lots of life in the verges. The surface consists of pebbles for the most part. Especially down below it is beautiful with a view of the valley. On the other side, on the Bosstraat, you will find an information board about the area.

If you walk from Bertembos to the Eikenbos (or vice versa) you will inevitably come to the Bosstraat that connects Bertem with Veltem-Beisem at some point. At this crossing of the road you will find an information board about Bertembos and the nature reserve De Koeheide that lies south of Bertembos. Of course, that Natuurpunt sign is not there for no reason. At this location there is a parking lot (where the Bosstraat and the short Oude Bertembosstraat meet) and at the same time one of the three starting points where you can start one of the Natuurpunt routes. The rest you can see on the board and on the spot and on the walking map and info (see the three arrows with the three starting points) on https://www.natuurpunt.be/natuurgebieden/koeheide#kaart By the way, you also have beautiful views here if you walk along the Bosstraat, because you are almost at the highest point of this fairly busy connecting road between the highway from Leuven to Brussels via Kortenberg and the highway from Leuven to Tervuren. Irrelevant info: one of my nieces lives at the end of the Bosstraat, so don't honk when you drive here ;)

A sunken road is a road that is so deeply worn that it lies between two slopes. It is the result of centuries of use and erosion. The most beautiful sunken roads can be found especially in hilly areas with a subsoil that easily forms steep walls, such as in Haspengouw and Hageland.
