GBA Mario Circuit

Mario Circuit is the first race course of the Flower Cup in Mario Kart: Super Circuit. This Mario Circuit is a rather plain stage and short in length, with few obstacles and Item Boxes to deal against rivals. It contains winding paths, however, such as a hairpin bend, or a curl path found before the home stretch. Next to the checked line there is a detour where racers can get a speed boost by running onto a Dash Panel located there. This track shares its music with Peach Circuit and Luigi Circuit.

Mario Kart 8 / Mario Kart 8 Deluxe
This Mario Circuit reappears in Mario Kart 8 and Mario Kart 8 Deluxe as the second course in the Shell Cup. Much like Bowser Castle 1 in Mario Kart 7, this is the only GBA classic course in the base Mario Kart 8 content. It now features a starting banner with black-and-white tires around the posts, various stacked tires and advertisements, and huts both filled with Toad and Yoshi spectators and oil cans. The large U-turn near the beginning of the track is slanted and separated from the track to act as an anti gravity section. There are also oil slicks that the players must avoid, similar to the four Mario Circuit courses from Super Mario Kart. The detour near the finish line also contains an added Item Box in addition to the Dash Panel. Unlike other courses from Super Mario Kart and Mario Kart: Super Circuit that have appeared as classic courses in more recent games, the road is also slightly banked through the curves.

The music has been modified to a slightly lower pitch and plays in B♭ Major on the first two laps and then in B Major on the final lap, as opposed to C Major in the original. Overall, the arrangement is based on the Mario Kart: Super Circuit prototype.

Shortcuts

 * To the right of the second line of Item Boxes, there is a Glide Ramp hidden by some trees that can be accessed by using a Mushrooms.

Staff ghost
The staff ghost for this track is Baby Mario on the Yoshi Bike, and Baby Luigi on the Sport Bike in Mario Kart 8 Deluxe's 200cc Time Trial.

Mario Kart 8 Original Soundtrack liner notes
"This circuit has been dramatically reworked, so we reflected that in the music by rearranging it and making generous use of a horn section."

Trivia

 * This is the only Mario Circuit not to feature any Warp Pipes.
 * In the Mario Kart 8 version, the U-turn is seen being lifted up into position by s during the preview. In the pit where the U-turn originally was are many Brick Blocks and Empty Blocks.
 * The course was originally known as Big Tree Circuit in a early prototype of Mario Kart: Super Circuit.
