Mount Wario

Mount Wario is the fourth and final race track in the Star Cup of Mario Kart 8. This course takes place on a huge mountain owned by Wario, where players must drive from the top to the bottom (similar to DK Summit in Mario Kart Wii and DK Mountain in Mario Kart: Double Dash!!). This is the only nitro course in Mario Kart 8 to be divided into three sections instead of three laps. Nintendo has said that the track is located in central Tanzania.

Course layout
The course is a three section race down a snowy mountain, split between three sections (like Wuhu Loop, Maka Wuhu, and Rainbow Road from Mario Kart 7, the remake of Rainbow Road from Mario Kart 64, and Big Blue in Mario Kart 8). It starts off in a large helicopter placed at the top of the mountain, with the racers driving out of it before landing onto the path. After a few downhill turns, the second portion of the track enters a cave, where Swoopers can be seen. There two anti-gravity sections ending with a hang-glider segment. Two flat rocks with boost pads are placed just after, before a boost ramp leads the racers into the Wario Dam area. After two 90° turns, there is another anti-gravity section with racers driving along the side of the dam, with boost pads going down streams (like in Shy Guy Falls).

After that, racers soon enter a snowy forest, that splits into two paths to start off. These two paths meet up to an area with rocks sticking out of the snow, which can provide a boost via tricks. Soon enough, racers enter the third section, which starts going down a skiing area with cheering Toads, Yoshis, and Shy Guys along with a Jumbotron. After a few turns, racers enter the final anti-gravity section, which goes down a ski jumping ramp with boost pads placed on various parts of the ramp. The section ends with a hang-glider section, where three boost rings are placed to help racers out. After two more turns, the race ends in an area next to a large log cabin, where the finish line awaits them.

Shortcuts

 * Just before the start of the second section, one can hit a small ramp and jump over a pit, cutting off the turn.
 * In the forest, one can cut in between the two paths to a hidden glider ramp by using a Mushroom.
 * One can cut off the last turn by boosting through the snow in the corner.

Trivia

 * This is the second track in the Mario Kart series that does not end at the same place in which the race started, along with Maka Wuhu and Big Blue, which is the third track that has that feature. Unlike Maka Wuhu, however, Mount Wario, along with Big Blue, in the Mario Kart series is not a looped race course.
 * This is the first track to have separate soundtracks for each lap/section instead of using the same soundtrack and speeding it up in the final lap/section, along with Big Blue, which is the second track to have that feature.
 * The second section of the course is the only section that has two separate soundtracks. In that section, when the player enters the forest area, the new soundtrack plays.
 * This course has the widest boost pad in the game, found just after the Dam section.
 * This is one of five courses to have an animation during the countdown, this being the helicopter door opening, the others being Excitebike Arena, Electrodrome, Bowser's Castle, and Twisted Mansion.
 * Although, technically, the animation is finished before the countdown starts.
 * This is the first Wario-themed course to not have Wario as the staff ghost (the staff ghost for this course is Waluigi).
 * The track's French name is Descente Givrée (meaning Frosted Downhill), thus not mentioning Wario. This means there is no Nitro Course with Wario's name in it in the French version.
 * Along with 3DS  Rainbow Road, Mount Wario is one of the longest courses in the Mario Kart series.
