Gem Stone Valley

Gemstone Valley is a hub world in Crash Team Racing. Although it is the second hub world visited, it doesn't have a role in the game until all four Boss Keys are obtained. There are two race tracks in Gemstone Valley: Slide Coliseum and Turbo Track. The player cannot access them until they get a certain amount of Relics. There is also a room where the Gem Cups can be accessed, but two Boss Keys are needed to enter. 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 Gemstone Valley.
