About Sonian Forest

The Sonian Forest is a vast, protected forest situated near Brussels, Belgium, known for its lush beech woodlands and rich biodiversity. It offers a tranquil escape for outdoor enthusiasts amid historic and ecologically significant surroundings.

Wilderness Landscape & Natural Heritage

The Sonian Forest, known locally as the Forêt de Soignes, extends over more than 4,400 hectares on the southeastern edge of Brussels, Belgium. This forested area is renowned for its impressive beech tree stands, some towering over 200 years old, forming a canopy that provides shelter to a variety of wildlife including deer and wild boar. Rich in history, the forest has been a vital natural resource and royal hunting ground since medieval times. Outdoor activities flourish here, from hiking and cycling along the well-marked trails to birdwatching in its quieter corners. The forest is part of the UNESCO World Heritage List as one of the Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe. Visitors are drawn not only by the serene beauty of the trees, especially during the vibrant colors of autumn, but also by historical features like the remnants of old abbeys and cultural landmarks such as the arboretum near Tervuren.
