It includes sections with and without rails, and an upward-shooting air tunnel for the first time in the series. Mario Kart: Double Dash!!'s Rainbow Road is set high above a city at night, which could be a reference to the "Mushroom City" track earlier in the game. It features rails at the starting/finish line only all other edges of the course are lined with jump ramps.
Mario Kart: Super Circuit's Rainbow Road is set in space, with Bowser's Castle from Paper Mario floating in the background. This version is also recreated in the sequels Mario Kart 8 and Mario Kart 8 Deluxe. The Mario Kart 64 version of Rainbow Road was featured as the first course in the Joker cup for the 1998 video game F-Zero X.

A version of this Rainbow Road also appears in the 'Joker Cup' of F-Zero X, where it is described as a "Psychedelic Experience" (and many of its rails are removed).

It features rails throughout the length of the course, roving Chain Chomps, a large drop right after the starting line, and neon-light images of various characters in the distance. Mario Kart 64's Rainbow Road is the longest course in the series, at three laps of approximately two minutes each. In Mario Kart 8 Deluxe, it can be downloaded to be retrofitted. The track appears as a bonus level in Mario Kart: Super Circuit and modernized in Mario Kart 7. Several flashing Thwomps appear throughout the course, and are uniquely able to wipe out racers just by touching them (as well as crushing them), although the Thwomps were removed when this track later appeared as a retro track in Mario Kart Super Circuit. Super Mario Kart's Rainbow Road is constructed from quadratic rainbow-colored tiles, with no rail at all, and all turns are at 90 degrees. The Rainbow Roads of some Mario Kart editions have been revised to be featured more than once throughout the series. It typically is among the most difficult to complete, since most of the Rainbow Road tracks have no rails to prevent the player from falling off the edges of the track during a turn, and often times have tight curves, steep slopes, and wavy grounds. Makes a great gift for kids ages 4 years and older, especially fans of Mario Kart™! Colors and decorations may vary.Rainbow Road customarily appears as the final track of each game. Once the karts get racing, they may face banked turns or a wavy road and must pass through the Item Box randomizer to win! Lights and sounds announce the winner at the finish gate.

The track set comes with two vehicles: an exclusive King Boo and Mario. Kids can use the electronic fair start gate to race up to five favorite Mario Kart™ 1:64 scale die-cast karts. Hot Wheels® and Mario Kart™ bring a dramatic video game level to life with the most iconic and final course in the franchiseRainbow Road! The 8-foot long track has five translucent rainbow-colored race lanes that can be configured straight or curved.
