So a very steep climb over the rocks, which ends with steep drops. Good luck!

At a time when bridges are legion to cross waterways, this ferry that connects Vétheuil and Lavacourt reminds us of another time. You will find more information on how to use it here: https://mairie-vetheuil.fr/tourisme-et-loisirs/vacances-vetheuil/le-bac-saisonnier.

The Église Notre-Dame de Théméricourt is a charming historic church nestled in the French countryside. The surrounding trails offer a mix of gravel paths and forest tracks, making for a picturesque walk. Once you arrive, take some time to admire the beautiful stone architecture of the church and the peaceful atmosphere of the village. It’s a great place to catch your breath and take a break before continuing your adventure in the Vexin Regional Nature Park.

During the Second World War, the German army chose this remote site to train its aircraft pilots. It was to house the devices that an immense concrete dome was built, which still stands solid as rock today in the Chesnay woods.
