GBA Luigi Circuit

Luigi Circuit is the first course of the Lightning Cup in Mario Kart: Super Circuit. It is the longest of the three circuits in the game and is the first Mario Kart track to ever take place in the rain, and would remain the only course with this distinction until Neo Bowser City in Mario Kart 7. This is the only Luigi Circuit course to not appear in the Mushroom Cup (meaning it is placed after a Mario Circuit race).

The course is set on what appears to be an airfield filled with rain puddles during a downpour, which when driven through cause drivers to spin out and lose speed. In the background are hangars numbered "64" and "65", flanking a radio control building. In the third lap, a Luigi blimp takes off and flies around (the same blimp can be seen in Sky Garden). The course features many tight turns suited for drifting and winds around circuitously several times, akin to a real-life kart racing track. This track shares its music with Peach Circuit and Mario Circuit.

Luigi Circuit reappears in Mario Kart DS as the third race of the Leaf Cup and in Mario Kart Tour starting from the 2023 Mario vs. Luigi Tour.

Course layout
This course starts on a straight road and that soon leads the player into a small curve to the right. Past that curve is a curve to the left, that soon leads into a tight U-turn that winds to the right. After the U-turn is a straight road followed by a U-turn to the left, which then leads to a slight curve to the right.

Past the right curve is a small U-turn to the right that leads into a straight road. After that small straight road is a tight turn to the left that leads into another straight road, this time longer than the last. After that straight road, there is a loose U-turn to the right that has a wavy road when the player proceeds. The road is not too wavy, but it is not straight either. Past the longest, straight road on the track is a sharp curve to the left that leads into another straight road. A U-turn then comes, making the player turn right and into the straight road that leads to the Finish Line.

Shortcuts

 * Before the second-to-last turn, the player can use a Mushroom or Star to boost through the gap in the crash barrier on the left.

Mario Kart DS
This version of Luigi Circuit makes its classic course debut in Mario Kart DS, as the third course of the Leaf Cup. The layout is mostly identical to its original one, with a few differences. The second to last shortcut located by the end of the course has been removed. Many trees have been added to various off-road locations of the course. The blimp now only starts to take off on the second lap, and the numbers on the two hangars have been changed into 00's.

Missions
The mission 4-8 is carried out on this course. Luigi must perform 9 drifts in a lap in 1 minute.

Mario Kart Tour
This version of Luigi Circuit returns in Mario Kart Tour starting from the 2023 Mario vs. Luigi Tour. The course has been significantly changed visually, with a forest now surrounding the track, breaks in the clouds, and the mountains being far taller and capped with snow. The layout has been simplified somewhat, with numerous bends from the original being straightened out and the windy portion being less windy. The sheds in the background have been redesigned, and seem closer to the course; some flagpoles and power lines also appear. Some elevation has also been added to the course, including two ramps. The blimp now bears the design of the Luigi Parafoil, still reading "Luigi Raceway". The width of the road appears to be somewhat thinner. A starting line banner has been added, featuring the classic Mario Kart logo with a satellite dish on the right metal pole on it. The colored blocks follow the pattern of the SNES courses instead of the GBA ones in Tour.

The course is a favorite of Rosalina (Chef), Daisy (Thai Dress), Daisy (Sailor), Luigi (Knight), and the Dry Bowser, Roaring Racer, Brown and Morton Mii Racing Suits

 * European website bio: "If the non-stop rain doesn't dampen your spirits, the skid-inducing puddles certainly will. Luigi's second namesake course couldn't be more different from the first; with seven hairpin bends and a pair of chicanes that will test your power-sliding powers to the max."
