This course has a ''[[Super Mario Galaxy]]'' theme to it, featuring a [[Launch Star]] and floating [[Star Bit]]s as elements of the track's design and theming. A large [[galaxy]] can be seen in the background, as well as sunlight on the Earth's surface. Both of the course's staff [[Ghost (Mario Kart series)|ghost]]s in ''Mario Kart Wii'' use [[Rosalina]]. The opening to the course's music is similar to the opening portion of [[Rainbow Road (Mario Kart DS)|Rainbow Road]]'s music from ''[[Mario Kart DS]]''; later, it uses "[[Egg Planet]]", [[Good Egg Galaxy]]'s theme, as a countermelody underneath its own main melody. An arrangement of this course's music appears as one of the selectable songs in ''[[Mario & Sonic at the Sochi 2014 Olympic Winter Games]]''.

This Rainbow Road returns in ''[[Mario Kart Tour]]'' as a [[classic course]] starting in the [[Space Tour (2023)|2023 Space Tour]]. It also returns in ''[[Mario Kart 8 Deluxe]]'' in the ''[[Mario Kart 8 Deluxe – Booster Course Pass|Booster Course Pass]]'' as the fourth and final course of the [[Spiny Cup]], and the final course in the game overall.

In ''Mario Kart Wii'', the course appears to be located over the eastern parts of North America, as well as some parts of Europe, Africa, and South America. In ''Mario Kart Tour'' and ''Mario Kart 8 Deluxe'', the course instead takes place above parts of Europe and Asia.  

The course is the longest original course in ''Mario Kart Wii''. It begins with a brief straightaway which has guard rails on both sides. The guard rails then immediately end as the track curves downward and racers drive along a very steep downhill. The downhill immediately contains a [[Dash Panel|dash panel]] that spans the width of the track, followed by two smaller dash panels on the right and left sides of the track respectively. The track then curves upwards, ending in a dash panel ramp. The first set of [[Item Box]]es can be found between this ramp and the steep downhill. After landing, racers gradually descend as they take a left turn followed by three dash panels and another left turn. On the outside of the second turn is a brief [[Half-pipe (object)|half-pipe]] with three Item Boxes on top and some short guard rails on both sides. After the turn there is a portion of track which is moderately wavy at the beginning of the race but becomes more and more wavy as time goes on; racers can perform [[Jump Boost|tricks]] off of the waves and can also make use of the dash panel ramp at the end of this track. There are also three pairs of Item Boxes along the wavy track.  

After the Launch Star ends, racers take a slight right turn followed by a slight left turn. Along the slight left turn are guard rails and four dash panels, and it ends with a unique type of half-pipe ramp that makes racers take a left turn over a gap while they pass through several star-filled rings. As racers land, the track is once again wider but quickly splits into two narrow paths. The right path quickly curves left to cross over to the left side while the left path quickly curves right to cross under to the right side, then both curve again to go the same direction. The right path briefly has guard rails on the right side while it is crossing over, but the paths otherwise function very similarly; each have a small dash panel on the outside of the curve before it crosses over, a small dash panel on the inside of the curve after it crosses over, and a ramp at the end. In both cases, the ramp has guard rails on both sides, three dash panels, and three Item Boxes on top. Racers then reach the final part of the track which is a singular wide U-turn to the left; it has no guard rails, curves downward on both sides, and takes racers through a tunnel of stars and a slight rainbow moving backwards. At the start there is a small dash panel on the inside of the turn, followed by a dash panel on the outside of the turn, and then one last dash panel on the inside of the turn at the end. This then leads into a slight turn right followed by the finish line.

Both the normal and expert staff ghosts of this course make appearances as staff ghosts in ''[[Mario Kart 7]]''. The normal ghost, Nin★Konno, appears as the normal staff ghost for {{classic-link|DS|Luigi's Mansion}}, while the expert staff ghost, Nin★Syun1, appears as the expert staff ghost for [[3DS Wario Shipyard|Wario Shipyard]].

The course layout itself has also received some alterations. The wavy part of the track is now consistent and does not change over time, the simple ramps that lined the holes at the figure-8 section are gone, the Launch Star now has a [[Glide Ramp|glide ramp]], and the previously unique half-pipe jump is now effectively parallel to where racers land from the jump, presumably due to the game's different half-pipe physics. Additionally, there are different Item Box placements: Most previous Item Boxes are gone, with the set just before the Launch Star and the set at the end of the split paths as the only retained ones. Instead, an item set is found just before the downhill and a set is found just before the wavy track. Lastly, many more guard rails appear along the sides of the track: The whole portion between the first dash panel ramp and the three subsequent dash panels is covered on both sides, the slight right turn after the Launch Star is mostly covered on both sides, the track just before the split path is covered on both sides, the right path is covered on the left side at its second curve, and the slight right turn at the end is covered on both sides. Unlike other classic courses in ''Tour'', Wii Rainbow Road's scale is larger compared to the original course, most noticeable following the figure-8 section.

The course has also received numerous graphical updates. The starting line and various other course elements now have technicolor ring designs. The road texture is now animated, with pinpricks of light following the path of the course. The background has received quite a few changes, such as the Earth being moved closer to the track and Saturn being moved from the last turn to being right after the cannon. Most notably, the moon is now modeled, is much closer to the track, and has a rocket ship based on the ones from [[3DS Rainbow Road]]. The floating arrows now take on their appearance from [[SNES Rainbow Road]]. The wavy road no longer has a different texture from the main road, and the road texture no longer highlights arcs for the subsequent half-pipes. The two launch stars at the rainbow tunnel are now larger and have been redesigned; they are now big stars with a ring encompassing the inner corners of them. The tunnel now cycles through colors. The launch star at the end of the rainbow tunnel now briefly spins when any racers pass through it, but does not launch them. The tunnel of light surrounding the last bend now has a pattern of rings moving forward with rotating sun-shaped entrances and exits, with the mandatory half-pipe jump also now having a version of this tunnel with simpler entrance and exit points.

This version of Rainbow Road reappears in ''[[Mario Kart 8 Deluxe]]'' as part of the sixth and final wave of the ''[[Mario Kart 8 Deluxe – Booster Course Pass|Booster Course Pass]]'' DLC. It is the fourth and last course of the [[Spiny Cup]], the forty-eighth and last course in the DLC and the ninety-sixth and last course in the game overall. It is also the only course from ''Mario Kart Wii'' added in the 2023 half of the Booster Course Pass not to be the third course of its cup. The course is largely based on its appearance from ''Mario Kart Tour'', only with significant visual upgrades. Unlike other Booster Course Pass tracks, the course model has not been upscaled from ''Tour'', meaning the track is narrower than most other ones in the pass, matching the ''Mario Kart Wii'' version. The entire course is now in [[anti-gravity]], making it the only Rainbow Road, and one of six courses in the game with this distinction, alongside [[Mute City]], {{classic-link|GCN|Baby Park}}, [[Big Blue]], [[Sky-High Sundae]], and the battle course [[Lunar Colony]]. Two [[Spin Boost Pillar]]s have been added along the track; one at the left turn after the figure-8 section and the right turn before the launch star tunnel. In the figure-8 section of the course, the ramps lining the holes and the Item Boxes above the half-pipes have returned, and there are Double Item Boxes at the set before the wavy track. Also, the boost panel at the end of the wavy track now remains slanted upwards, instead of moving along with the wave. Additionally, the wavy section does not get increasingly bumpier as the race goes on. The required half-pipe jump has been modified from ''Tour'' to be closer to the ''Wii'' original, though it is not identical. The dash panels along the second curve of each split path are now on the outside of the curve, and each dash panel along the final U-turn has been moved to the opposite side of the track. Even more guard rails have been added along the sides of the split path part of the track: Both paths are fully covered on the outside of both of their turns. In the case of the first turns, there are no guard rail gaps between them and the start of the section, and in the case of the second turns, there are no guard rail gaps between them and the dash panel ramps. Unlike in ''Mario Kart Tour'', the course has reverted to having three laps instead of two sections. It is the longest three-lap course in the game, beating [[Toad Harbor]] from the original ''Mario Kart 8'' and {{classic-link|DS|Waluigi Pinball}} and {{classic-link|Wii|Maple Treeway}} from previous waves of the ''Booster Course Pass''.

Visually, the course is also noticeably paler in color compared to how it appeared in ''Mario Kart Tour'', making it closer resemble how it originally appeared in ''Mario Kart Wii''. Additionally, the tiles on the road are smaller compared to how they appear in ''Tour'', giving the road somewhat of a resemblance to ''[[Mario Kart 8]]''{{'}}s own [[Rainbow Road (Mario Kart 8)|Rainbow Road]]. The Launch Star rainbow tunnel has colors stretching from the start to the end like in ''Mario Kart Wii''. The other two tunnels, the one for the half-pipe jump and the other for the bend before the start-and-finish, have their designs look like how the tunnel for the bend was designed in ''Mario Kart Wii'' with the latter having the lights and the rainbow moving backwards once again. The sound effect of the wavy road, the sound effect for the cannon, and the sound effect of the rainbow tunnel of the U-turn have been brought back after being absent in ''Mario Kart Tour''. The minimap has been rotated 90° counterclockwise and lacks a drop-shadow. Additionally, the effect of characters burning up when they fall off the course is retained from ''Mario Kart Wii'', though the effect is shorter and racers fall off more horizontally.
