After the loop is a final straightaway to the finish. A straightaway follows with a Wario sign present, then follows a final looping section, where a Bowser sign is seen near the end of the track. A Toad neon sign can be seen after the drop as well as a wide right turn. Shortly after the hairpin bend is a short straightaway followed by a smaller drop and small uphill stretch. Racers turn around a corkscrew to reach a hairpin bend, where signs of Donkey Kong and Yoshi are seen. After the bridge is a corkscrew loop with a large star in the center and a Boo sign at the corkscrew's outside. Following the loop is a steady downward road that crosses over the steep drop where a Mushroom sign can be seen. After the ring, there is a wide loop with neon signs of Mario, Peach and Luigi on the loop's outside.

The course starts with a huge drop followed by a gentle uphill stretch passing through a rainbow ring. The player can make a long jump over it by hopping with precise timing when the road starts to descend, as seen in this picture. The course returns in Mario Kart 8 and Mario Kart 8 Deluxe as the fourth and last course of the Lightning Cup. Roving Chomps slide through the course in a zigzag pattern, and colliding with them will cause the player's kart to crash and be thrown into the air. Moreover, a big three-dimensional smiling star lies in a curved section of the track. Neon-light pictures of the eight playable characters and a portrait of a Boo and a Mushroom are found in the distance and float in the void. The track features a transparent multicolored glass path with star-shaped rails running throughout the entire course. The track differs from the other Rainbow Roads in that it has rails throughout the entire track. It is the longest racecourse in Mario Kart 64, at 2,000 meters (2 kilometers), and requires about two minutes per lap, making it the longest three-lap track in the whole series. Rainbow Road is the fourth and last race of the Special Cup in Mario Kart 64, as well the sixteenth and last course in the game.
