Rainbow Road is -as usual- the final course of the Special Cup in Mario Kart: Double Dash!!. But unlike all previous Rainbow Roads, which were set in deep space, this version of Rainbow Road is floating above a city (presumably Mushroom City). This setting idea wasn't reused until Mario Kart 8 with the re-edition of N64 Rainbow Road. This course is very difficult, sporting few railings and multiple speed boosts.
