Back Door



Back Door is a level in the Valley of Bowser in Super Mario World. It is similar to the Front Door of Bowser's castle, but skips over the majority of the level, starting at the "dark" room. The eight doors are skipped entirely, making Bowser's Castle much easier. The only difference in the "dark room" from the Front Door path is a Midway Gate just before the fight to Bowser. The battle with Bowser is unchanged, as is the credits and ending scenes.

It can be accessed through a secret path in the Valley of Bowser, specifically after the completion of the level Valley Fortress, which many players consider to be more difficult than any of the rooms accessed at the Front Door of Bowser's Castle.
