Things to see and do Briis-Sous-Forges

At the start of the Ulis, the 12 kilometers that await you with sports pleasure and heritage discovery. And for the reason: your first step is only the Domaine Saint-Jean-de-Beauregard! Classified as a historic monument, it is open to visit, so why not take advantage of your walk to stop there? If its th century castle is the «nail of the show», don't miss the park, its vegetable garden and its pigeon house. Your journey will then lead you to the domain of Janvry, another architectural pearl of the XVII - unfortunately it does not visit. Not far away, stop before "the Song", another remains: Gérard Philippe and Coco Chanel stayed there. Then go to the Hameau hamlet. Then, before reaching Gometz-la-Ville, at the level of the lift station, go up the path along the castle park: you will then find the road that will bring you back to the right port.
