Rainbow Springs Golf Club occupies a 240-acre property in Mukwonago, Wisconsin, with the Mukwonago River flowing through the grounds. The course was designed by golf course architect Roger Packard and opened in 1971. The layout features bentgrass fairways and greens, and several holes run alongside or cross the river. The club maintains a driving range with both natural turf and artificial mats, plus a practice putting green. The clubhouse includes a restaurant and bar that serves lunch and dinner, and the pro shop stocks equipment and apparel. The property also contains a 32-lane bowling alley that operates year-round. The golf course is open to the public and accepts tee times through an online reservation system.
