Rainbow Road

Rainbow Road is the final track of the Special Cup, like in every other Mario Kart game. Again, it's made up of multi-colored tiles. It shows the planets and rockets in the background. Like the tracks Wuhu Loop and Maka Wuhu, this track only has one lap, instead of the original three. This Rainbow Road is divided into three sections. Those sections resemble laps. There are banners at the end of each section. The music is a remix of the Rainbow Road in Mario Kart 64, like'' Mario Kart: Double Dash!!. ''There are 2 different variations of this new theme. The 1st variation plays while driving on the rainbow tiles, and the 2nd variation plays during the 2nd section when the player is driving on the moon. It should also be noted that, when the 3rd section is reached, the end of the music, which is the remix of the end of Mario Kart 64's Rainbow Road plays first, instead of the start of the music. If the player turns around and goes back to the moon section after crossing the entrance to the 3rd section, the music won't change back to the 2nd variation. Unlike past Rainbow Roads, this incarnation features the player driving on non-rainbow tile surfaces such as the moon and rings of a planet resembling Saturn. The first part has the drivers race on the rainbow tiles and the second part has them race on the rings of the planet for a short time. The third part brings them to the moon with Chomps coming out of the craters, and finally the track returns to the rainbow tiles.

Also, Super Mario Karts Rainbow Road 'returns as the final track of the Lightning Cup. This course, N64 Luigi Raceway, GCN Daisy Cruiser, and Rosalina's Ice World are the only courses in this game to have no gliding pad. This is one of the shortest courses in this game, unlike the other Rainbow Roads. This is the only Rainbow Road so far to reappear as a retro track in another Mario Kart (not including when it, along with all other SNES tracks, appeared in Mario Kart: Super Circuit). Unlike its reappearance in Mario Kart: Super Circuit, Star Thwomps make a return in the course. The Thwomps now hit the track forming undulations on it, off of which the player can do tricks. Also, metallic grinding noises can be heard when the Thwomps are driven under. Ramps are also added throughout the course, taking the place of the yellow bumps that appeared in Super Mario Kart. There is also a starry background rather than it being completely black; in actuality, this was implemented earlier in Mario Kart: Super Circuit. Super Mario Kart composer Soyo Oka considers this course's theme one of her favorite compositions.
