3DS Mario Circuit

Mario Circuit is revamped again in Mario Kart 7 for the Nintendo 3DS. It is strongly based off the Mario Kart DS version of the track, and is the second race in the Flower Cup. In this, unlike the other Mario Circuit tracks, players can drive through Peach's Castle.

Course layout
The track takes place on a large grassy field with sand roads, Mushroom Trampolines, pipes, blossoming peach trees, a lake, and Peach's Castle. The course starts on a small straight road and after two turns which a large curve with pink leaf appears. Then the player jumps off of a ramp, landing on a Mushroom Trampoline. Then a similar road to that of Mario Kart DS's Mario Circuit leads the way up to Peach's Castle. Then the road enters in Peach's Castle and, after a 270° turn, a glider pad enables the driver to fly out of the castle. Then a number of pipes appear that shoot out air, along with some Big Goombas. A very long, large pipe similar to the ones form Mario Kart 64 and Mario Kart DS appears, in which drivers must drive through in a curve leading them back to a long road going back to the finish.

Trivia

 * In an early trailer of Mario Kart 7, when Mario Circuit was shown, there was originally a bouncy Mushroom where the players glided out of the side of the castle, probably because the concept of gliders hadn't been implemented into the game.
 * Of all the Mario Circuits that feature Peach's Castle, this is the only one in which the castle can actually be raced in.
 * The blossoming peach trees in this track was later reused for the revamped Royal Raceway in Mario Kart 8
 * In addition, the falling flower petals from the trees are actually intended to serve as a 3D effect of the Nintendo 3DS. When the 3D mode is activated, the falling petals seem to "pop out" of the screen.
