Bowser Castle 3 is the fourth course in the Star Cup in Super Mario Kart.

Many consider this the hardest track in the game. Not only are the racers quite hard to catch up to, but the track itself is difficult to traverse, with many walls, jumps above lava, sharp turns and thin corridors. This track has not appeared in a recent Mario Kart game yet.


The track starts with a quick first turn which leads racers straight to a thin walled corridor. This first trap can easily ruin a race, even if the player arrives first into the corridor. come after that another left turn straight into the other big section; multiple jumps above the lava pool, to reach very small patches of stone. Four paths open to the racer, before another left turn.

Straight after the turn, a hidden zipper that most inexperienced players miss. Another thin walled section leads to the central hairpin, heading right.

From the central hairpin, three branches open up. The left one has coins and item boxes, but needs to be reached. Others have zippers set straight after jump bars, making unaware players avoid them due to the jumps.

After the triple corridor, another hairpin heads left, into a final S curve which leads back to the checkered line.

In Mario Kart: Super Circuit this track is the same but, the Thwomps and the zipper are removed and has the GBA Bowser Castle 1 background.
