Terra Drome (テラのひみつアリーナ lit. Secret Arena of Terra in Japanese) is the fifth and final battle arena in Crash Nitro Kart. It is unlocked when all four purple CNK tokens are acquired from crystal challenges. It is set inside of a temple with a cylindrical shape. In the center is a statue of Krunk, holding up a bridge that arches across the top of the arena. Around the statue, are little totem heads sorrounding a ring. If the ! Crate on the bridge is destroyed, fire shoots out of the front and sides of the totems. The music here is the same as the music used for the Inferno Island track.
The arena returned in Crash Team Racing Nitro-Fueled.
