Pierrefonds Castle is a fortified castle built at the end of the 14th century, located in Pierrefonds, in the Oise. It is a medieval castle rebuilt for Napoleon III by Viollet-le-Duc.

Very good conversion of the old railway line into a greenway: some passages are lit, others are in the shade, a wooded area for the most part, it is a very pleasant greenway to do. Too bad it does not continue to the D33 and that there is this intersection with the farm path.

The towpath that crosses La Ferté Milon is a must. As the section is closed to bicycle traffic, it is a must-see hiking trail, rather than a must-see mountain bike trail; and given the terrain, it would even be more Gravel than mountain bike, if bicycles were allowed to circulate. The Ruins of the Castle is a good place to stop: for the history, the panoramic view and the restaurant.

While strolling along the Canal de l'Ourcq, you will pass by the Marolles lock with an interesting view of the canal, the lock, an island, the church and the castle. https://aufildelourcq.org/index.php https://fr.wikipedia.org/wiki/Marolles_(Oise)

Magnificent lock on the Ourcq canal at the eponymous village. It is surrounded by a beautiful green setting which gives it even more charm.
