Arboretum de La Roche-Guyon

The Arboretum de La Roche-Guyon is a botanical garden spanning 12 hectares within a large regional forest in the Val-d'Oise department. The collection displays various tree species in organized sections that represent the flora across the entire region.

The arboretum was established in 1990 by the state forest authority to display and protect local tree species. This initiative came from a desire to make the region's natural diversity accessible to visitors.

The garden is organized by region, with each area displaying tree species native to a specific part of the territory. Visitors can experience the area's natural diversity directly through this layout.

The arboretum is free to enter year-round and has parking areas for visitors. Well-marked paths allow you to explore the garden at your own pace.

The arboretum uses grass strips that resemble rivers, creating a three-dimensional botanical map of the entire region. This creative design makes the geographic arrangement of different tree species immediately visible.
