About
Sonian Forest (wouden van Zijde) is the largest ancient beech forest in Belgium and one of the world’s most extensive beech habitats. Located on the outskirts of Brussels, it offers visitors a lush green escape just a short train or tram ride away. The forest covers approximately 5,000 hectares and is famed for its towering beech trees, whose trunks form a cathedral‑like canopy that has earned the forest the nickname "Beech Cathedral". Recognised as a UNESCO World Heritage Site in 2017, the Sonian Forest is part of a network of 94 European beech forests that together preserve the continent’s oldest forest ecosystems. Within its boundaries live more than 150 bird species, numerous mammals such as deer, foxes and bats, and a diverse range of flora including rare mosses, lichens, and a thriving coniferous understory. This biodiversity, coupled with well‑marked walking, cycling and horse‑riding trails, makes the forest a living laboratory for nature lovers and everyday visitors alike. Beyond its natural beauty, the forest offers a variety of recreational opportunities. There are dozens of marked trails ranging from short, family‑friendly loops to longer, more challenging routes. Visitors can also explore the arboretum at Tervuren, visit the pristine forest reserves, or simply relax on one of the many picnic areas and dog‑walking paths. The Sonian Forest’s welcoming atmosphere, mixed recreational offerings and easy accessibility make it a must‑visit destination for both locals and tourists.
