Craters on Uranus (ウラノスうらおもて lit. Uranus Back and Front in Japanese) is the fifteenth and final race course in Crash Tag Team Racing and the third and last race track within Astro Land. It is the last track to be unlocked and it is the longest track in the game.
- The observatory at the end of the course has an upper path that can be accessed if the player goes to a control panel in Astro Land overlooking the course and pressing the buttons, causing the telescope to knock a ramp down, allowing the players to reach it.
- This course's name, when pronounced aloud, can be heard as "Craters on your anus". This is most likely a joke from the developers, or a very unfortunate mistake.
