"Yo ho ho in a bottle of Wumpa Whip! Ahoy Matey! Batten down your hatches and swab my poop deck, says I. Heh. Avast there, ye swabs! Salty venture awaits thee beyond these cursed portals o' doom! Heh, heh, heh." - Willie Wumpa Cheeks introduces Mystery Island
Mystery Island is the first hub in Crash Tag Team Racing. The world has a pirate theme and features a large pirate ship in the middle of it. It also features three race tracks, each named with a connection to pirates or underwater. The name of the three tracks are: Tiki Turbo, Pirates of the Carburetor and Deep Sea Driving. Additionally, there is a battle arena called Jungle Rumble. The world has many Die-O-Ramas that involve being eaten by sharks, getting shot out of a cannon, squished by gears and being blown up by monkeys.
Like every other world in the game, there is a jump pad which needs to use a certain amount of crystals in order to get to the next power gem. In this case, eight are needed to access it. The jump pad is located next to Cortex, who is the only other playable character that is seen in Mystery Island.
The track Deep Sea Driving also has a secret shortcut that can be accessed by shooting a cannon at a ship, causing it to drop onto the track.
List of things that can be found in this hub

- The way Crash acquires the Power Gem in this level is a parody of the 1981 action adventure movie Raiders of the Lost Ark, where the main protagonist Indiana Jones (portrayed by Harrison Ford) retrieves a golden idol from a booby-trapped temple in Peru. Crash does it in the exact same way as Indiana Jones, with placing a bag full of sand on the spot where the Power Gem was.
- The Iceberg Lab from Crash Twinsanity can be seen melting in the background.
- Two of the levels in this world share their names with stages from previous Crash Bandicoot games, with Jungle Rumble sharing its name with the sixth level from Crash Bandicoot: The Wrath of Cortex, while Deep Sea Driving with the race track from Crash Nitro Kart.
