On January 1, 2022, the city of Aarschot purchased the former Schoonhoven campsite, with the intention of turning it into a fully-fledged relaxation and recreation park. The park is best known for its ponds, but major works are underway here. In 2024, there was already a lot of change with the necessary inconvenience for walkers, but the construction of a swimming pond and a beach sports field simply requires work. By the Easter holidays of this year, some things should already be ready. More about the future of Park Schoonhoven and the plans at https://www.aarschot.be/zwemvijver-en-strandsportveld-park-schoonhoven The plan of the swimming area, the beach sports field and the sunbathing area can be found at https://www.aarschot.be/file/download/20300/8D604DCABF67B2786F8436882871AEA7 You can also stay informed via https://www.aarschot.be/updates-schoonhoven

Always an ideal stop. This bench was made by the family business of Boomwerken. You will come across it when you "climb" past the chapel in Testelt to the viewpoint on the Voortberg (at the transmission tower).

The restoration of the Molenheide nature reserve started in the early 2000s. In addition to the restoration of the heath, a fen was also restored during these restoration work. This had become overgrown and was released during restoration with the aim that the mineral-poor water would attract specific animal and plant species that are rare in Flanders.

Birdwatching hut De Kuilen overlooks the large pond of Demerbroeken, which is probably not coincidentally also called De Kuilen. Watching waterfowl is allowed, but not touching. Making noise and hanging extra food balls is also not allowed. Furthermore, when looking from the hut and in general, people are requested to take into account other visitors so that hikers, spotters and photographers can enjoy together and observe birds, according to - among other things - the information board.
