Arboretum Robert Lenoir
The Arboretum Robert Lenoir is a woodland area with more than 3000 different trees and shrubs spread across approximately 22 hectares near Rendeux. The planting is arranged in natural-looking groups and rows, with pathways leading through various sections featuring meadows, dense tree clusters, and small clearings.
The arboretum was founded in 1937 by Robert Lenoir, who purchased large tracts of land and began planting trees collected from across Europe. After Lenoir's death in 1989, the Walloon regional government took over the site and preserved the original collection as it had expanded.
The name Robert Lenoir honors the founder who shared his passion for trees with others. Today, locals and visitors use the space for quiet walks and to spend time with loved ones amid the varied plant life.
The site is open from sunrise to sunset with no entrance fee, making it easy to visit at your own pace. Pathways are designed for comfortable walking, though wheelchair access is limited in some areas.
The founder tested trees from across Europe and discovered that some normally cold-sensitive species thrived here in the Ardenne climate. This collection reveals how adaptable certain trees can be to the cold mountain conditions.
