Forming the heart of a country estate with long avenues of linden and chestnut trees, the park at Vaeshartelt palace includes a 7-hectare English landscape park dating from the 19th century. A large number of giant old trees, some of which date back to the 18th century, give the park its character along with small canals and ponds. Many structures of the pleasure garden originally commissioned by Regout, an industrialist from Maastricht, are still visible today and are currently undergoing restoration.

A broad avenue of linden trees leads up to the palace from the gatekeeper's house at the entrance to the estate. The new teahouse is located on the park’s highest elevation, the traditional ice cellar. Viewers can enjoy the best view across the park to the palace from here.

The Secret Garden was created at the palace in 2005 and features an avenue of quince trees as well as walnut trees, herbaceous beds and pools. The former farmstead with its farm garden is located beside the palace. A vineyard has been added in recent years.

In 2012, the park was extended by adding the "New Gardens of Vaeshartelt", a rambling fruit and vegetable garden where old varieties from the region are cultivated. A futuristic bee and exhibition building constructed for Floriade 2012 has found a home here.
