Rood Klooster Lake

Highlight • Lake

Nice place as a start for many walks / bike rides in the Sonian Forest. Rood Klooster was founded in 1369.

This is definitely worth driving. The routes there are wonderful. Also for those who like to drive through deep puddles and mud, they will find something to their liking on mini single tracks

Royal Lodge of Groendaal

Highlight (Segment) • Monument

Old part of the Groendaal hyppodrome, built under the impulse of King Leopold II in 1896. Nice part to drive along coming from the Sonian Forest

This road is called Hakenstakendreef today and connects the current Groenendaal station with the tunnel under Sint-Jansberglaan, which leads you to the former racecourse (and the restored Royal Box).

The Hakenstakendreef is incidentally mentioned in a building application as the "chemin d'accès" (access road) that led to the now-nonexistent Groenendaal-Hippodroom station. See hoeilaart.weleer.be/renbaan-groenendaal/2904

At the beginning of the avenue, you will find information boards about the forest; at the end, by the tunnel, is part of the former racecourse car park where this station once stood, and where racehorses, as well as people, were brought by train.

You are therefore walking in a once very popular area, as at its peak, around fifty horse races were organized in Groenendaal (before the First World War). But you won't see much more than the gravel road and trees (until you reach the remains of the car park and the tunnel).
