An extraordinary arboretum in an extraordinary forest. Situated in the municipality of Tervuren, the Geographic Arboretum sits like a crown on the head of the majestic Sonian Forest, on its north border. The collection is set in a beautiful landscape park, between imposing alleys and along a labyrinth of grassy open valleys. More than a tree collection, this is a collection of forests, or forest types, more precisely. Countless trees and shrubs from the North, the West and the East of North America, from Central and Mediterranean Europe, from the Middle and Far East of Asia are grouped here by region of origin in some hundred sections, covering a total of 120 ha.
