|List of Levels|
Valley Fortress is the only secret level in the Valley of Bowser.
This level is one of the hardest fortresses in Super Mario World. Ironically speaking, this being one of the hardest level on Valley of Bowser, makes the Bowser boss fight a joke. Most of the level contains dodging spikes that fall from the ceiling and dodging fireballs from the lava.
