Zonienwald (Sonian Forest)

Highlight • Forest

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).

Domaine Solvay

Highlight • Castle

A few minutes from Brussels, in the heart of Walloon Brabant, the park houses the Château de Béthune, built in 1842 on the model of the châteaux of the Loire. It is surrounded by a perfectly symmetrical French garden, decorated with decorative statues. The Château de La Hulpe is now owned by the Walloon Region.

The castle is not open to the general public, but is suitable for all kinds of events.

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

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.

Enjoying the Sonian Forest is easy from the various access gates. These access gates are located on the edge of the forest, are easily accessible and are therefore the ideal starting point to explore the forest. There are eight access gates.

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.
