The Secret Of Battle Fort (simply referred to as Battle Fort) is an adventure course and a multiplayer course that is exclusive to Super Mario 64 DS.

The Battle Fort can be found in Princess Peach's Castle's courtyard underneath a brick. As Yoshi is unable to break the brick blocks, only Mario, Luigi, or Wario are able to enter the course in the single player mode.

Battle Fort has two floors. The enemies in the course are Chuckyas, Heave Hoes, Goombas, Bob-ombs, and Big Steelies.
