The Sonian forest is a large forest surrounded by the Brussels communities and with traffic lanes going through it. These threats to a nature site have already caused a lot of damage. Still, a lot of energy is put in maintaining this forest as it is of immense significance to keep the lungs of Brussels alive and functioning.
You can enjoy this forest by walking, cycling or horse back riding. It is the home of various mammals (bats, deers), reptiles and birds. Next to this you’ll find plants, trees and several flowers and mushrooms. Their quantity is declining..
This forest has a rich history as a royal hunting place, fortunately this became forbidden in the 1970’s. The forest is mostly used for recreational and educational activities. During weekends the forest gets crowded by families and cyclists where as during the week you can walk for hours without seeing a soul.
Since this forest can be entered via it’s surroundings it is impossible for me to tell you how you should get there, it really depends on your departure point. If you are in the center you can take bus 95.
It is actually not too far to go there by bike, just head for watermaal bosvoorde and find a park entrance.
