Arboretum de la Sédelle

The Arboretum de la Sédelle is a botanical garden in a granite valley with approximately 400 different plant species, centered around the Sedelle River. The collection emphasizes maple trees, which form a significant part of the garden's horticultural focus.

This garden was created from a former agricultural valley that lay abandoned for 40 years before being transformed. In 2005 it received the Remarkable Garden designation from the French Ministry of Culture.

The site expresses the philosophy of Gardens in Motion, where cultivated plants blend with natural vegetation patterns that evolve over time. Visitors observe how human design respects the spontaneous growth of the landscape.

The garden operates seasonally from May through October with specific weekday hours, making it best to check opening times before planning your visit. Paths wind through the valley, so comfortable walking shoes are recommended for exploring the various plant areas.

The collection holds one of Europe's most comprehensive maple collections with more than 100 different cultivars and species. This specialized gathering is officially recognized and maintained by the French network for botanical conservation.
