Le Vallon is a Belgian parkland course located in Vieux-Genappe in the Walloon Brabant province, approximately thirty kilometers south of Brussels. Designed by Jean-Manuel Rossi, the course occupies rolling terrain characteristic of the Brabant countryside, with mature trees and natural water features shaping the playing corridors. The layout reflects Rossi's approach to integrating golf holes within the existing landscape rather than imposing dramatic earthworks. The routing moves through varied elevations and wooded sections, requiring golfers to navigate both strategic positioning and elevation changes. Water comes into play on several holes, and the tree-lined fairways demand accuracy from the tee. The course serves members of Club de Golf D'Hulencourt and welcomes visitors, functioning as a regional facility in an area of Belgium where golf development has grown steadily since the late twentieth century. The club operates within the Walloon golf community, which includes several established courses in Brabant wallon and neighboring provinces. Vieux-Genappe itself sits in agricultural and residential countryside, providing a quiet setting removed from urban density while remaining accessible to golfers from Brussels and the surrounding region. The course offers a traditional parkland experience suited to the Belgian landscape and climate.
