What is to be remembered from this route is the passage through the Carnelle forest. However, there are too many roads on the Isle Adam and along the Oise. No particular difficulty.

This tower was built in 1863 for the fantasy and vanity of the wealthy Baron Joseph Louis Léopold Double, descendant of a noble family whose districts date from the 14th century. It is used as a hunting venue. The Baron, as an informed collector, seeks above all pieces that belonged to historical figures and brings together a good number of art objects and furniture from the castles of Versailles, Fontainebleau, Rambouillet, etc. Through his marriage to Pauline Eugénie Collin, the great-granddaughter of Doctor du Mangin, he became the owner of the Château de Saint Prix. Wishing to establish a fiefdom worthy of his fortune, he bought the woods located in the commune from the successors of Baroness de Feuchères. Baron Double designed his property in keeping with the taste of the time: footbridge connecting his park to the new estate, pilasters marked with his initials at the entrance to the paths, rotunda and various underground passages under the Route des Parquets, artificial cave, canals and retention basin at the Marie pond, chalet, Chinese kiosk, and three towers of which the Plumet tower is, today, the only survivor. The Plumet Tower was restored in the early 2000s by France Télécom, a mobile telephone operator, following the installation of a relay antenna at its summit.
