Nice location because you can imagine yourself in different parts of the world by the large number of exotic trees that were planted here sorted by their habitat. This allows you to walk from the West Coast of America to China through the different forests that were planted to imitate nature there as closely as possible.

Beautiful to walk in any weather. Many paths around here are also bike-free, which is still pleasant for the walker.

The Sonian Forest, also known as the Zoniënwoud, is a large forest area centrally located in Belgium, southeast of Brussels. It covers approximately 4,421 hectares and is best known for its old beech trees, some of which are over 200 years old. The forest has a rich history dating back to the Iron Age and has had various functions over the centuries, such as providing firewood and timber for the construction of houses and ships, and as a backdrop for hunting scenes. The current forest landscape with deciduous trees has its origins in the Austrian period (1714-1795).

The path which crosses the Solvay estate and which passes near the Château de La Hulpe is in good condition and has only a few holes filled with water... but easily avoidable.
