The route enters the woods of the castle area, follows the natural valleys and crosses the water features. On 60 hectares, its layout respects the centenary trees, the undergrowth full of ferns and the immense mass of rhododendrons. Created in 1990, it is the work of the American architect Robin Nelson and the French landscape painter Thierry Huau who knew well how to preserve the natural beauty of the site. Note that the course has been modified and that the two new holes (12 and 13) were designed by the French architect Manuel Rossi.
