Definitely stop by Ernesto koffie (right at the roundabout Walensebaan and Smisstraat), a cozy little food truck right by the ponds. There are also cozy seating areas provided at the food truck itself. Delicious coffee and wonderful pastries. Ideal for a refueling stop. Super friendly service. Open Wednesday to Sunday from 10:30

This tour goes for kilometers through the forest. In spring it is beautiful with the hyacinths and wood anemones. In summer nice and cool.

From here you have a good view of the landscape in which the Battle of Waterloo was fought, you can still clearly see the slope in the landscape that allowed the British to take up a good defensive position.

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.

Two important lordships formed the basis of the current Hoeilaart: the lordship of Ter Heyde south of the IJse on the one hand, and the lordship of Holaer or Hoeilaart north of the IJse on the other. Here once stood the castle of the Ter Heyde lordship from the fifteenth century. That lordship ceased to exist after the abolition of the ancien régime. The current castle was built in 1858 on the orders of baron Jean de Man d’Attenrode (mayor of Hoeilaart from 1854-1878) and his wife Maria Carolina d’Ormesson. It is therefore not a remnant of the old lordship. BUT: the chapel and former closed farm next to it are. This building has now, as others have mentioned, been given a different function and dominates the view in the park.

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.

In front of the park is a French garden with ponds, flower beds and statues, which extends to a series of ponds that receive their water from the Voer.

I was pleasantly surprised here: a former road through the forest is now a paradise for cyclists and pedestrians. I can't imagine cars there.👍🙏😜🚴
