Bowser's Castle is a track found in the Bowser Cup in Mario Kart Arcade GP.
The track starts out in front of the castle. You'll cross a bridge, and then go through a hallway. You'll then cross over a bridge, similar to the one found in the Bowser's Castle on Mario Kart: Super Circuit. Taking a U-Turn here leads you past a Bowser statue, and into another part of the castle. Rounding a few curves inside, You'll pass through a hallway, with knight's amour on the sides. After this, you'll pass through a throne room, with Bowser Jr. cheering the races on. You'll go onto a bridge after this, and pass through another U-turn. Once outside, you'll drive down a stone path, take another turn, and go through the starting line.
