Want to get away from it all and unwind? Head to Villiers-le-Mahieu, in the Yvelines, just 45 minutes from Paris, where an incredible château built in 1642 on the ruins of a 13th-century fortress awaits you, complete with majestic moats emerging from a park dotted with century-old oak trees. Transformed into a hotel—the first property of the Les Maisons de Campagne brand and certified by Clef Verte—the venue blends historic stonework with modernity, combining whimsy with elegance. Spread across the château and two outbuildings that can be rented privately (the Cottage and another country house), the 98 rooms are decorated in shades of gray and feature stylish garden chairs, which can also be found throughout the estate—perfect for lounging or reading a novel. The more adventurous may prefer a game of tennis on one of the two courts before cooling off in the outdoor pool—open from June through September—or unwinding in the wellness center, which offers a spa, yoga classes, and weekend fitness sessions. As for meals, they bring everyone together with hearty, seasonal cuisine served in the light-filled dining room, on the terrace, or in the inner courtyard—not to mention the legendary brunches served every Sunday.
