Bowser's Castle (Mario Kart Arcade GP)

Bowser's Castle is the first course in the Bowser Cup in Mario Kart Arcade GP and Mario Kart Arcade GP 2, alongside Castle Wall. Racers first enter the castle through an opening that resembles Bowser's head, not too different from Mario Kart: Double Dash!!. They go through a hallway and end up in Bowser's throne room, covered with lava. After this area, racers can see Thwomps (their design is very similar to ones seen in Super Mario Bros. 3) and a hallway with medieval armor for Koopa Troopas. Bowser Jr. can be seen, standing on his throne and cheering at players. The racers eventually leave the castle and arrive back at the starting line.

When this course is revisited in the third round of the Bowser Cup, Kamek will occasionally appear to narrow down certain pathways with tall rows of blocks, starting with the second round.

The track's layout is later reused and modified for another Bowser-themed course in Mario Kart Arcade GP DX, being Bowser's Factory.
