GBA Riverside Park

Riverside Park is the third race course of the Mushroom Cup in Mario Kart: Super Circuit. It takes place in a jungle near a river. The opening for the music bears similarities to the music for DK's Jungle Parkway from Mario Kart 64. A resembling animal noises can also be heard throughout the song. Lakeside Park functions as a more difficult counterpart to it, and its background music takes many cues from Riverside Park's.

Riverside Park reappears in Mario Kart Tour starting from the Animal Tour, and in Mario Kart 8 Deluxe as the second course of the Fruit Cup in the Booster Course Pass.

Course layout
After the first turn there is a straight path then the player come across the first crossing of the river. There is a spot on both sides of the river where there is a bridge. There are crash barrier squares that block some potential shortcuts. Shortly after the first crossing, the player actually goes over the river. There is a U-turn here and a shortcut (see "Shortcut" below). The player goes around a road branch in the river and goes around another U-turn, and from there the player goes straight and cross the river to the final stretch: a loop around where the player jumps over the course, as pictured below.

Shortcuts

 * After the very first U-turn, the player can use a mushroom and jump over the water from one dock to another.
 * Also, after the player jumps over the river, on the first U-turn, if they turn about 100 degrees and drive to the river, there is a narrow pathway across the branch.

Mario Kart Tour
Riverside Park makes its classic course debut in Mario Kart Tour, where it debuted in the Animal Tour. Here, the course has been completely redesigned, featuring elevation and scenery changes.

The course now includes more bridges, more ramps, and waterfalls. Many rocks and rafflesias have been added to the section before the final loop. The bridges throughout the course are now much higher compared to the rivers compared to before, and are also held up by support beams. The large U-bend at the beginning has been made much smaller and no longer has a left turn before it. Some mud has been added to the course. The jump across the river now takes place on a diagonal portion of the course. The shortcuts have been removed, though new grass cuts have been added. The rest of the layout is recreated relatively faithfully. The loop that precedes the finish line runs through a cave, that features some more bridges. The jump after the loop goes through a waterfall at the end of the cave. The whole course now has a yellow hue. A starting banner has been added that is held up by two rocks wrapped in ivy and vines and has the classic Mario Kart logo. In the T and R/T variants, a Noshi is added to the course.

Much like most other GBA courses in Mario Kart Tour excluding the Bowser's Castle courses and Cheep-Cheep Island, the course received a new arrangement of its background music using synthetic instruments. The course also appears as Riverside Park R (reverse), Riverside Park T (with ramps), and Riverside Park R/T (reverse and with ramps).

The course is a favorite of White Shy Guy, Mario (Swimwear), Yoshi (Kangaroo), Cat Rosalina, Daisy (Thai Dress), Kitsune Luigi, and Petey Piranha (Gold). It can also be a favorite of Light-blue Shy Guy (Explorer) if he reaches level 3, and Blue Shy Guy and Poochy if they reach level 6.

Mario Kart 8 Deluxe
Riverside Park returns in Mario Kart 8 Deluxe as part of Wave 4 of the Booster Course Pass. It appears as the second course of the Fruit Cup. The course is based on its appearance from Mario Kart Tour, but with significant visual upgrades. Similar to, the cartoony clouds have been removed in favor of a more realistic skybox, with the water featuring a more realistic design. Ptooies now appear as enemies throughout the course, blowing Dash Mushrooms and Bananas that they will drop if hit with an item. The starting line bridge is wider than it is in Tour, and now extends past the width of the dirt path afterwards. A few other walls were also extended compared to the Tour iteration of the track. The Dash Panel on the first bridge has been replaced by a trickable wooden ramp. Traffic cones have been added surrounding the mud parts of the course. The river that goes through the course also now flows in one direction. The bridge located at the beginning of the course is wider and now has visible mold growing on it. The cave section has been turned into a slippery road (similar to ) and the standard Tour ramp has been replaced by a trickable metallic ramp. The "Mario Kart" text on the starting gate is now much less saturated and has a white color compared to the red and orange text from Mario Kart Tour. A small patch of mist and vapor is now visible above the bright by the cave entrance below the waterfall. Inside the cave, bright blue glowing mushrooms have been added, illuminating the interior of the cave with a faint blue color. Koopa Paratroopas have been added as spectators at the bridge with the ramp, and Toads, Yoshis, and Shy Guys have been added as spectators along the colored blocks halfway through the course and the forest with the rafflesias. The scarlet macaw from is present in this course, sitting atop a vine in the muddy section before the cave.

Similarly to, ambient sounds of animals can be heard throughout the course, including monkeys and birds in the course's opening. Additionally, the music has been redone completely and is now performed live, as opposed to the sequenced soundtracks it had in both Super Circuit and Tour.

Internally, Riverside Park is referred to as "Cnsw_47", implying it may have originally been intended to be the third course of the Boomerang Cup.
