Ghost Valley 3 is the third course in Special Cup in Super Mario Kart. It was subsequently reused in Mario Kart: Super Circuit. It contains holes in the course and has very few side rails.

Ghost Valley 3 is themed like the Ghost Valley 1 and Ghost Valley 2 tracks: racers drive around a wooden, dark bridge surrounded by Boos. Being the final Ghost Valley track, it has the sharpest turns, narrow roadway, and large holes in the road itself. As in all Ghost Valley courses, side rails break upon being hit, which exposes racers to drops. The course has fewer side rails than the first two Ghost Valley courses. Jump pads are also placed in front of holes to cause players to fall off the course.

The course reappears in Mario Kart: Super Circuit, and is the second track in the Extra Special Cup. It uses the background from Broken Pier. The zipper and the legs holding up the track are removed and an extra item box can be found after the second jump pad.
