In Mario Kart: Double Dash!!, Rainbow Road is throttled with Boost Pads, and near the end, it hosts a large pipe that launches the player. The number of barriers to prevent the player's downfall is borderline minimal, making the course very difficult. There are several statues of 3D rainbow-colored items and characters floating above the player. It uses a pipe-like cannon that shoots the player straight up, which has later been used for Mario Kart Wii's Rainbow Road.
- This stage takes place above Mushroom City.
- in 1 Player only, Stars will fall on the track due to the fact that falling stars come down on the track a lot (and many times becoming a Star item on the track). Hitting these will make the player invincible (because that is what a Star item does) unless they fall off the course.
