The arboretum was established in 1978 by Count and Countess de Bonneval on a former sandy heathland.
It contains one of the largest collections of North American trees in Europe.
The garden is organized into four distinct geographical zones, including sections dedicated to North American, Asian, and European flora.
It holds 'Collection Nationale' status for its specific genus, including extensive Magnolia and Cornus collections.
The site utilizes the natural sandy and acidic soil of the Sologne region to cultivate rare calcifuge (lime-hating) species.
The estate remains a privately owned, family-managed site, which preserves its intimate, non-commercial atmosphere.
The Arboretum des Grandes Bruyères is a 12-hectare botanical garden located within the Orleans Forest in France. It is renowned for its extensive collection of North American trees, particularly magnolias, cornus, and sequoias. The site features a series of thematic gardens designed around a central arboretum, focusing on conservation and biodiversity. It is a classified 'Jardin Remarquable' (Remarkable Garden) recognized by the French Ministry of Culture. The grounds include a large pond and winding paths that weave through specialized horticultural displays. The landscape design emphasizes naturalistic transitions between various woodland zones. The arboretum functions as both a public leisure space and a site for scientific observation of exotic tree species. It is situated in the heart of the Loiret department.

Wear sturdy walking shoes as paths consist of gravel, grass, and uneven forest soil.
Bring insect repellent during the summer months, as the proximity to the forest and pond attracts mosquitoes.
Check the website for flowering calendar updates, as peak bloom for magnolias and dogwoods occurs during specific short windows in spring.
Avoid visiting during heavy rain as the woodland paths can become muddy and slippery.
Closed from November through March; typically open daily during the spring, summer, and autumn seasons.
