Celestial Valley is a course in Kirby Air Ride. It resembles a spooky valley, with many cliffsides and enemies.
After the first turn is a large tree root, and on top of it is a Copy Chance Wheel. Next comes a small log bridge followed by a wooden bridge, which leads into a narrow turn. Afterward is a large waterfall with several caves behind it, each with rails racers can grind on. The caves all meet up at a valley with many bumps, which ends at an upward moving waterfall that sends racers onto the platform above. In this area, there is running water that can make the racers move faster, and the water flows into a narrow passage of several turns. Finally, it drops off at a vine rail leading to the finish line.
