Ghost Valley 1 is a course both found in Super Mario Kart and Mario Kart: Super Circuit. It is the 3rd course in the Mushroom Cup and 3rd in the Extra Mushroom Cup. Unlike other courses, there are boxes around the track instead of barriers. These boxes act like barriers but if hit once, they disappear and enable racers to fall.
After the final ramp, use a feather or use a mushroom and jump onto the narrow platform, cutting off the last turn. This could be tricky to complete for some players as there are no barriers or boxes to help prevent you from falling.
