On any sandy pit on a curve that would normally slow you down, use a mushroom to cross over it.

When you get to the rotating floor, go around it all the way until you see the small entrance.

Near the halfway point of the course, use a mushroom to cross the water and land on a dock. This is not easy, but saves a lot of time.

When you get to the second green bridge, look to the left to see a cloud that goes across to the other track. Hop over it to get to it, then hop back off to avoid falling off. Note: This may require some practice.

This course is one of the longest in the game, but it has a shortcut that can cut a lot of time off your lap. It is possible to jump over the wall to the left of the starting line by using any one of the four small jumps there. Although you can make it over the wall without the assistance of any speed boosting item, a Mushroom or Mini-Turbo assist is helpful. Approach the wall at a high speed so that you are driving directly at it as you reach the peak of the small hill. Jump right before you hit the wall and you will fly over it. The timing requires some practice, but once you master it, it is not too difficult. It is also possible to jump back over the wall on the other side of the starting line, but the return jump is much more difficult and requires precise jump timing and aim.

Just after the first two turns, go straight and you will see a gap in the wall. Hop over it to get ahead.

This course is a tangle, as shown in the introductory map. However, there are a few shortcuts that will help you defeat just about anybody. Follow the course until you reach the maze part. Immediately go left and keep towards the left. The first shortcut is to stay left on the narrow part of the course. After doing that, you will hit a little checkered ledge, and see a large red and white sign on the left pointing to the right. This is the difficult part. Accelerate as fast as possible and stay to the far right. As soon as the rail on the left side ends, pull a hard left powerslide off the road. You will continue the powerslide onto the upcoming road after you land, and if done correctly, you will have shaved off at least ten seconds. This requires a lot of practice.
