Pinnacle Country Club in Milan, Illinois occupies 160 acres of gently rolling terrain bordered by the Rock River on the south. The course was designed by architect Robert Trent Jones Jr. and opened in 1991. Its bentgrass fairways and greens are maintained to USGA standards, with a consistent irrigation system that draws from on-site wells. The layout includes strategic bunkering, several elevated tee boxes, and water hazards on eight holes. Native oak and hickory trees line many fairways, while fescue grasses frame the rough. The clubhouse, a two-story brick structure completed in 1992, contains a pro shop, grill room, and locker facilities. Practice amenities include a 10-acre driving range with target greens, a short-game area with sand bunkers, and two putting greens. The club hosts local high-school tournaments and USGA qualifiers each season.
