N64 Yoshi Valley

Yoshi Valley is a race track in Mario Kart 64. It takes place over a canyon and there are many twists and turns. In fact, there are so many different paths that the game cannot keep track of the current standings until the end of the race. There are also several Spinies that can disable turning and slow racers down for 1.5 seconds. Near the end of the course, there is a giant rotating Yoshi Egg that can easily flatten any player to disable their movement for about five seconds. The track uses the same music from Moo Moo Farm. It returns in Mario Kart 8 as the final course of the Leaf Cup and a playable Battle Stage.

Course Layout
Due to the unique design of the course, there are many different routes that can be taken from the beginning of the maze to the end. The maze begins after a right turn over a bridge shortly after the starting line, and the end is where the Bridge Route connects to the Main Route, after which is a left hairpin turn that then leads to the spinning Yoshi Egg, after which is a long narrow bridge that brings the racers to the grassy field with the finish line.

The Main Route can be accessed by going either direction at the start of the maze, if the player took a left then the main route will be to the right of the Narrow Route and if the right was taken then the next two lefts must be taken to the Main Route. The Main Route begins in an underpass under the Long Route and a small jump, where there will be a group of Spinies and then a right turn to the end of the maze.

The Bridge Route is located to the right of the Main Route and is found by taking the first right and then a left and the Bridge Route will be straight ahead, alternatively the player could also drive towards the Main Route and then hang a right just before passing under the Long Route. The Bridge Route passes under both the Long Route and the final stretch of road, the gap between being connected by a small narrow bridge, afterwards is a horde of Spinies on a steep left turn, which then leads to the end of the maze after a short drop.

This route is avoided by most players as it is the one route that is clearly much longer than the others and is often not worth taking, especially with the presence of the Narrow Route that quickly brings racers close to the end of the Long Route. It can be reached by taking the first two right turns, where the road will make a sharp right turn and a somewhat straight path that passes over both the Main and Bridge Routes. After the Narrow Route joins up to this path there is a comparatively wide right turn that leads to a small drop to the Main Route shortly before the end of the Bridge Route.

The Narrow Route is found by taking the first two lefts from the beginning of the maze, and joins up with the end of the Long Route. This route can be risky due to how narrow it is and the long fall if racers don't successfully stay on the road, especially if two racers attempt to take this path at the same time.

Mario Kart 8
Yoshi Valley is set to appear in Mario Kart 8, with a few changes done to the track. Many changes have been made graphically to be more relatable to the Yoshi species, most notably how it is now set in the Wild Yoshi Sanctuary and many trees and bushes present with Berries hanging from them. The starting banner is now wooden with a nested green Yoshi Egg placed on top of it. There are also multicolored Yoshis throughout the track waving. The egg towards the end is now smaller, and has some coins following it, but still serves as an obstacle. The dirt road outside of the maze is wider though there is less space in the off-road grassy area, with various fences and wooden bushes blocking the way, but a ramp has been added as a shortcut which the player can perform a trick on, and any short drops originally present in the track are now small trick ramps that can also be driven back over for Battle Mode. Guardrails have been added throughout many of the paths, most likely due to how infamous the course was previously, and to tone it down for Leaf Cup and prevent certain unintended shortcuts. The game also tells the players which place they are in, but the counter can be slightly inaccurate at times due to how complicated the track remains. The Spinies have also been replaced with Goombas.

All of the original paths remain intact, though have been given slight changes to even out the lengths of them; the most significant being a cannon in place of the Long Route. Other changes include Bridge Route having the bridge removed and the left turn at the end is more flat and runs through a cave. Taking the first left upon entering the maze and then the first right now leads to the end of the Long Route instead of the Main Route, the Narrow Route is now a typical shortcut over a wooden bridge, and as such the Main Route can only be accessed by taking a left just before the Bridge Route and thus is much more easily missed.

Instruction manual description
''Steep canyons and a very large egg... Hmm... How does this course relate to Yoshi? To make one lap, you can take any route you like through the complicated maze, but without keeping a careful eye on the course radar, you might drive the wrong way and end up returning to where you started. Of course, leaving the course is forbidden.''
