Sonian Forest: The Absolute Essentials

The Sonian Forest, a UNESCO World Heritage site, spans over 4,000 hectares across the Brussels-Capital, Flemish, and Walloon regions. This ancient beech forest features historic landmarks like the 14th-century Rouge Cloître priory and the Château of Val-Duchesse. Visitors can explore the Domaine Solvay in La Hulpe, which houses the Fondation Folon museum, or visit the circular Glaverbel Building and the former Boitsfort racecourse. Accessible via the Groenendaal and Hoeilaart train stations, the area offers a network of trails connecting historic chapels, castles, and serene parklands.
