3DS Mario Circuit

Mario Circuit is the second race course of the Flower Cup in Mario Kart 7. It is strongly based off the Mario Kart DS version of the track. Unlike other Mario Circuit tracks, where Peach's Castle is a background element, this course allows players to drive through the castle. This rendition of Mario Circuit returns in Mario Kart Tour, where it appears in tours starting with the Tokyo Tour. This track shares its music with Toad Circuit.

This is the only Flower Cup course in Mario Kart 7 to not have a different name in British English versions.

Course layout
The track takes place on a large grassy field with sand roads, floating Brick Blocks, a Mushroom Trampoline, pipes, blossoming peach trees, a lake, and Peach's Castle. The course begins with a small, straightforward path with two turns, after which pink flower petals begin falling out of the trees on a long bend to the left. Activating the 3D effect of the Nintendo 3DS gives the effect of the petals popping out of the screen. After a ramp, the racers bounce off a Mushroom Trampoline into a curvy section leading towards Peach's Castle, which they then enter. After a spiral upwards, a Glide Ramp launches the drivers out of the castle into an area where pipes blow out wind (allowing for Tricks to be performed) and Goombas appear. Following this is a very large pipe, not unlike the one found in Mario Raceway, which drivers must curve through to reach the finish line after one small bump in the road.

There are a number of shortcuts available in this track. Between the first and second turns, drivers may use Mushrooms to use a ramp in the middle of the grass. Mushrooms can also be used to cut grass on the corner before the Mushroom Trampolines. There are two additional ramps in front of Peach's Castle. There is yet another ramp to the left when the racers exit the castle, and a rail to the left along the pipe, both of which save some time.

Mario Kart Tour
This version of Mario Circuit makes its classic course debut in Mario Kart Tour, starting with the Tokyo Tour. The course has undergone minor changes. Peach's Castle has been redesigned, with the entrance to the castle now having doors leading into the spiral upwards. The starting line has a new look that resembles a garden gate. Like all other courses, it has a reverse, trick, and reverse/trick variant, known as Mario Circuit R, Mario Circuit T, and Mario Circuit R/T respectively. The reverse and trick variant was introduced in the 2019 Winter Tour.

Trivia

 * In an early trailer of Mario Kart 7, when Mario Circuit was shown, there was originally a Mushroom Trampoline in the pit which players normally glide over, due to gliders not having yet been implemented.
 * The blossoming peach trees in this track were later reused for in Mario Kart 8.
