Mario Kart World is packed with secrets, and if you’re aiming for 100% completion, you’ll need to dig a little deeper—especially when it comes to unlocking the game’s 4 hidden tracks.
With 32 total tracks, that means 28 are available through regular play, and the final 4 are locked behind specific requirements.
Here’s how to unlock each of the 4 secret tracks so you can enjoy the full Mario Kart World experience.
🏞️ How to Unlock Acorn Heights
Acorn Heights is the first secret track you’ll unlock, and it’s part of the Special Cup. To unlock it:
- Complete all 7 Grand Prix Cups, which covers 28 races in total.
- Your placement doesn’t matter—just finish all the races.
Once that’s done, Acorn Heights will unlock automatically in the Special Cup.
🏁 How to Unlock Mario Circuit
Another secret track you’ll unlock alongside Acorn Heights is Mario Circuit. The process is exactly the same:
- Finish all 7 Grand Prix Cups, no need to come in first.
- Once completed, Mario Circuit becomes available as a playable track.
🏟️ How to Unlock Peach Stadium
Peach Stadium also joins the list of unlockables once you’ve cleared the Grand Prix section:
- Complete all 7 Grand Prix Cups (28 tracks total).
- Again, placement doesn’t matter—just focus on completing every race.
Peach Stadium will unlock shortly after and become playable.
🌈 How to Unlock Rainbow Road
And finally, the one everyone’s waiting for—Rainbow Road.
- Rainbow Road is the final track in the Special Cup and also becomes available in VS Race mode.
- To unlock it, you must complete all 7 Grand Prix Cups—that’s the key.
Once you’ve done that, you’ll unlock this legendary track as the 32nd and final race in the game.
If you’re chasing 100% completion in Mario Kart World, unlocking these 4 tracks is a major step. The best part? You don’t have to win every race—just finish them.
