N64 Choco Mountain

Choco Mountain is a racing track in Mario Kart 64 and Mario Kart DS. This track is the third course in the Flower Cup and features falling rocks as obstacles. Halfway through it, a strange chocolate pyramid can be seen. The course reappears in Mario Kart DS in the Leaf Cup and in Mario Kart Tour as the signature course of the Exploration Tour.

Water can also been seen in this course. Before the finish line, there is a curve with a water trap in it, where the racers could fall into. In the 50cc difficulty level, the curve is protected by a banister where the players could not fall into the trap; however, the banister disappears if the player chooses a higher difficulty level than 50cc. In Mario Kart DS, there is no banister present at all. While it is one of the shortest tracks in Mario Kart 64, this is deflected in Mario Kart DS.

Course layout
The race starts out on a straight road that eventually leads to a curve to the right. The curve also features a twisty road and a row of Item Boxes for players to use. After the curve and the twist, the road continues curving until a U-turn leads players into a longer straight road. This straight road leads to an overhang, where players originally started.

Past the overhang, another curve to the left takes players to the bottom left part of the course, where the road is somewhat straight, but not as straight as the preceding road. Players then turn left, pass a row of item boxes, and drive over a small hill that makes players fly. After the small hill, there is a somewhat sharp curve to the left. In the 50cc, banisters are set to prevent players from falling into the water below. However, the banisters are not present in the 100cc, 150cc, and EXTRA modes. Boulders fly out on the sharp curve to flatten and slow down any player that is present in their landing spot.

After the falling boulders, a right curve takes players to a straight road, with the road below them to the left. In Mario Kart 64, if players fall into the road below, they must race the part they were just in, also with the penalty of losing any position if players are behind them. After this dangerous place is a curve to the left, with three sets of hills that also send players flying into the finish line, where they start the track again.

Mario Kart DS
This course returns as a retro course as the second course in the Leaf Cup. Not many changes were made, aside from the graphics, and the banister that protects the player in Mario Kart 64 in 50cc and Time Trials was removed completely. The course was available in Wi-Fi.

Mario Kart Tour
Choco Mountain reappears once more in Mario Kart Tour, where it makes its debut in the Exploration Tour. There is now a scarce amount of foliage on the borders of the road. A pit and some dead trees have been added at the left of the first turn and some small ramps were added just before the face of the mountain. After entering through the mountain, the track now has a cavern section with Swoops, crystals and off-road shortcuts. A glider section with a pit below and on the right has been added at the end of the cavern. A concrete wall and Fish Bone fossils were added in the part with the boulders. The last turn now has a off-road part that the players can use as a shortcut. Additionally, more signs were added to the track. The course is favored by Pink Gold Peach, Mario (Chef), Captain Toad, and Wario (Hiker).

Mario Kart 64

 * Instruction manual bio: "This mountainous course climbs and descends through extreme altitude differences and has continuous sharp curves. Your skills at sliding can greatly affect your rank or time. Watch for the signs along the way warning where large rocks might fall on you."
 * Website bio: "Dangerous mountain roadways make this course tricky"

Mario Kart DS

 * American website bio: "This mountain path is brimming with hazards. Whether you're dodging a boulder or testing your nerve along a cliff edge, Choco Mountain is no joke."
 * European website bio: "If Choco Mountain was a chocolate bar, it would be the kind with teeth-breaking crunchy bits inside, rather than a smooth and creamy centre. Here, deadly rockslides knock the unwary driver into an abyss, while you fight to maintain control over the undulating terrain."
