One of the most unusual spots in the Paris region is the Desert de Retz, at Chambourcy in the Yvelines. This 18th-century Anglo-Chinese garden is one of the few to have been preserved in its original state. This enchanting place, once frequented by the likes of Marie-Antoinette and Thomas Jefferson, stands out for its fanciful constructions. You'll also enjoy discovering the many remarkable trees that dominate the landscaped area.
