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 can not 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.

One of the paths is following the direction of the Yoshi flags and going right. Turn left and go onto the bridge, then make a very sharp turn. Doing this will put the player at the end of the maze and onto the path that all karts go on to the finish line.

Mario Kart 8
Yoshi Valley is set to appear in Mario Kart 8, with a few changes done to the track. It seems a few more paths have been added, the most significant having a cannon which blasts drivers across a fair portion of the track. Now, the game tells the players which place they are in, but this still can be a bit messy due to how complicated the track remains. The beginning is now much more narrow, with various fences and wooden bushes blocking the way, but a ramp has been added which you can perform a trick on. 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. There is 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 Spinies have also been replaced with Goombas.

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.''
