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.

Robert Lenoir planted the arboretum between 1937 and 1987, gathering rare species on the banks of the Ourthe. The Walloon Region acquired the site in 1991 and has maintained it since, while Lenoir's grandson continues to add to the collections.

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 collection is identified in botanical registries by the code ROBLE, and the site holds 2,509 living plant accessions covering 1,661 taxa in cultivation. Its special collections focus on Euonymus and Sorbus, alongside the maples, magnolias, prunus and rhododendrons. The grandson of Robert Lenoir still adds to the plantings.
