Mario Circuit 3 is a course in Mario Kart Wii. It is a very old course; it comes from the Flower Cup of Super Mario Kart making it a retro cup course. The course is found in the Lightning Cup of Mario Kart Wii, however. The course is a long, almost symmetrical track with many twists and turns, however no obstacles other than Pipes and Oil Slicks scattered throughout the track. The course is walled with colorful blocks. One curve in the track is extremely sharp and can be performed best by slowing down or drifting. At the end of the track is one zipper that can be used to take the lead or catch up at the last minute. The course also has a shortcut. Soon after the sharp twist, there is a less sharp curve. The gap in the crash barrier (blocks) there can be used to avoid the curve. It is best to use a Mushroom (or Triple Mushrooms), Golden Mushroom or Star here to avoid slowing down.
