Small stone church surrounded by greenery and groves of lavender, which make it an idyllic place to stop and recover for a few moments. At the border of Yvelines and Eure-et-Loire, you are in the middle of the countryside and all to the west of Ile-de-France, far from the noise of Paris!

This pretty little village embedded in the Vaucouleurs valley owes its charm in particular to the hilly landscape that surrounds it. The town is crossed by a diversion channel of the river which fed an old mill.

Estate built in the first third of the 17th century, having preserved its park, its outbuildings and its alley of lime trees from the end of the 18th century. The castle stands opposite the church of Tilly, it was bought and saved from ruin in 1936 by François Delalande, his daughter still occupies it today. It is a beautiful Louis XIII-style residence, flanked by its two towers with an original domed roof, in a six-hectare park entirely surrounded by walls.

Pier to cross the Seine on the Catarina, the ferry that connects Vétheuil and Moisson-Lavacourt. A little hidden behind the trees. It's quite fun to do and the short break on the boat offers the best view of the village of Vétheuil. The ferry is in service from April to October, on weekends and public holidays, and on Friday mornings for access to the Vétheuil market. Free passage (12 people per crossing – dogs, bicycles and strollers accepted) Schedule : Friday: 10 a.m.– 12:30 p.m. Saturday, Sunday and public holidays: 10:30 a.m. – 12:45 p.m. and 2:45 p.m. – 6:20 p.m. Interruption of service between 4:30 p.m. and 4:45 p.m. In October, end at 6 p.m.
