Mario Kart 7/Shell Cup

Luigi Raceway
Luigi Raceway first appeared in Mario Kart 64. This course is fairly simple, featuring two wide loops and two differently lengthed linear sections.

Shortcuts
There is an alternate way on the platforms next to the curves.

Bowser Castle 1
This short course, the only retro course from Mario Kart: Super Circuit in 7, contains a few Thwomps, plenty of coins, and a few item boxes. There are sandy areas that slow down karts.

Mushroom Gorge
Mushroom Gorge originally appeared in Mario Kart Wii.

Luigi's Mansion
Originally the last course in the Mushroom Cup for Mario Kart DS, Luigi's Mansion takes place in a mansion, a graveyard, and a swamp. The mansion itself encourages sliding around 180 degrees, due to the 270 degree turn.
