3DS Rosalina's Ice World

Rosalina's Ice World is the second race course of the Special Cup in Mario Kart 7. Located on an icy road, it is the first and only course in the Mario Kart series to be owned by Rosalina, and as a result draws inspiration from the Super Mario Galaxy installments. The drivers can dive underwater where some Penguins swim, in an area which strongly resembles the main planet of Cosmic Cove Galaxy. This is the second Special Cup course to take place in a snow- or ice-themed area, the first being Vanilla Lake 2 in Super Mario Kart. The course returns in Mario Kart Tour, making its first appearance in the Rosalina Tour.

Course layout
The course starts off in a snowy area with snow covered domes and a structure resembling the Comet Observatory off to the side. The racers then slight to the right and pass through a halfpipe-like area with the right edge as a pit and some coins. After entering a cavern, a small ramp allows racers to jump onto an icy area with penguins and a few coins, with the first lap giving them a choice of the icy path, or an underwater cavern filled with more coins than above. The second lap, however requires racers to go underwater unless they have a Mushroom, use the Super Mini-Turbo, or drive straight after the curve (at least eight coins needed) and hold the Circle Pad down, as the kart goes higher when this is done. After the icy area, racers go through another cavern, but with icicles protruding from the ground, which can be shattered. The road then splits and gives the racer a choice of taking a narrow road with a Dash Panel, where a Starshroom can be seen on the right, or a wide path with no boosts. A final jump is then encountered and finally the racer turns to the finish line. In the background of the course, the starting planet of the Gateway Galaxy can be seen in some areas. When racing online, the underwater penguins are absent.

This is the only Nitro Course in the game which does not involve gliding.

Shortcuts

 * At the very beginning, there is a patch of snow to the right that can be cut across with a Mushroom or Super Star.
 * Just before the spiral section, by drifting off the side of the wall to the right at an extreme angle, it is possible to clear a good section of the chasm. How much the player skips depends on how extreme the angle the player took was. This can be done with or without a Mushroom.

Mario Kart Tour
Rosalina's Ice World reappears in Mario Kart Tour, starting with the Rosalina Tour. It retains most of its appearance from Mario Kart 7, though with a few minor differences. The planet seen in some areas is not the starting planet from Gateway Galaxy anymore and is now a 3D model (there are actually three different viewable planets during the race). It is a favorite of King Bob-omb, Peach (Explorer), Fire Rosalina, Nabbit, Shy Guy (Gold), and Lakitu (Party Time).
