Let's stay on the trails
In nature, only the path is man's territory. Stay on the paths to avoid trampling species. Don't take shortcuts and respect fragile spaces
The "Sentiers du Patrimoine" (Heritage trails)
41 walks through local historyWash houses, mills, churches and chapels, castles or mansions, old forges and farms, old railway lines, covered walkways... reveal their particularities before the eyes of walkers! The Heritage Trails shed light on important elements of municipal history but also on the men who made its history. They most often include a table for reading the local landscape. Created by the Vexin Français Regional Natural Park in collaboration with the French Federation and the Departmental Hiking Committees, these trails promote local heritage through specific and well-integrated signage, improving visitor reception and site identification.
