Wild Valley is the only unlockable golf course in Mario Sports Superstars. It is unlocked when players clear the Star Cup in the golf portion of the game. The course features more narrow Fairways, strong winds, trickier, more sloped Greens, and many sloped elevations that make traversing this course more difficult than the previous three courses. The course occasionally rains, reducing the power of drives and putting. This course is the one played on when players play the Champion's Cup.
