Traffic-free bike rides around Forêt de Soignes - Zoniënwoud
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 https://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).

Two picnic benches at a point where various paths meet, located between the (natural) play area on one side and the chapel and ponds on the other. At the chapel there are regular benches to sit on.

The Groenendaal racecourse was built in 1888-1889 on the initiative of Leopold II in the middle of the Sonian Forest, next to the road to Waterloo, and in 1892, as part of easy access, it received its own railway connection to Groenendaal station. To realize this racecourse, approximately 100 hectares of forest were cleared at the end of the 19th century. King Leopold II had his own box there, located between two metal grandstands for the public. After the First World War, this area was used for the dismantling of weapons and ammunition left behind in the Westhoek. German prisoners of war had to clear mines under the supervision of the Belgian army. During a fire and the subsequent explosions of ammunition on May 6, 1919, the hippodrome's grandstands and buildings were heavily damaged. After another explosion in November, the ammunition depot was completely dismantled in 1920. Two years later, the racecourse was restored and the grandstands were rebuilt. The royal box for Albert I was not rebuilt until 1924. Its appearance was completely different from the pre-war grandstand. When the current appearance came about is not entirely clear, although the current box is attributed to Albert I in the literature, see also monogram.

Here in the courtyard you can get something to drink and eat (be careful, it is only open until 6 p.m.), which is a bit of a shame.

A solid wood bridge crosses the Horseshoe Pond, which is thus divided into two parts.

Nice sighting when out riding, there is a gravel track passing through and a bit later you'll meet a pasture with beautiful Highland Cows!
