This route was built on a former railway sidetrack. It offers a beautiful recreational area, from the gates of Beauvais to the hedged farmland and wet meadows of the Pays de Bray and then Normandy.
The route follows the banks of the Thérain river, past post-war buildings and glimpses of Saint-Pierre cathedral, an unfinished Gothic masterpiece, before joining the Avelon river, its small bridges and ancient mills, and the Saint-Paul amusement park.
The route then offers a variety of bucolic landscapes: ponds, beautiful farms and small houses that remind us that Normandy is close at hand. Numerous gaps through the curtains of trees and shrubs reveal fields and pastures of varied colors.
To the west of Lachapelle-aux-Pots, the verges are wooded and much shadier. At Saint-Germer-de-Fly, the greenway leaves the Oise to join the Seine-Maritime.
