Gem Stone Valley

Gem Stone Valley is a hub world in Crash Team Racing. Although it is the second hub world unlocked, it doesn't have a role in the game until all four Boss Keys are obtained. There are two race tracks in Gem Stone Valley: Slide Coliseum and Turbo Track. The player cannot access them until they get a certain amount of Relics or Gems, depending on the track. There is also a room where the Gem Cups can be accessed, but two Boss Keys are needed to enter and at least three are needed before the first Cup can be unlocked. The entrance to Oxide's race is here as well.

Trivia

 * Despite taking place in Citadel City, the player receives the Boss Key from Pinstripe's race here. The cutscene of Pinstripe talking also takes place in Gem Stone Valley.
