Ghost Valley 3 is the final Ghost Valley course. It is the third course in Special Cup in Super Mario Kart. With almost no walls, players must be careful. Oil Slicks are spilled along some parts of the track, slowing down players. Like the other two, this one also has Boos that move slowly around the layout.
This track is arguably one of the hardest tracks to drive on in the Mario Kart series.
This course reappears in Mario Kart: Super Circuit, in the Extra Special Cup.
