Forest Fortress

Forest Fortress is a secret Fortress found in Super Mario World. It can be accessed by completing the level Forest Secret Area in the Forest of Illusion. By completing this level, the player gains access to Star Road, located in front of Star World 5. Although officially part of the Forest of Illusion, it is situated out of the forest on the overworld map.

Normal Exit
Mario starts out in a moving sidescrolling area. He finds Columns throughout the area. After getting past the first Column, Mario also finds Grinders moving along dotted lines close to the ground. The player may have to use the Spin Jump to get past the obstacles. After progressing through the area, Mario will also find bottomless pits under the Grinders; however, these bottomless pits are completely covered by Exclamation Mark Blocks if Mario has activated them before the level. At the end of this area, Mario finds a door taking him to the next area in the fortress.

In the next area, Mario starts out on a platform above the lava. A Grinder immediately falls from a big rectangle platform at the top of the screen. Mario jumps over a pit full of lava, avoiding the Podoboos that jump out. After climbing the next platform, Mario jumps into a small pit at the bottom of the screen, which contains two Grinders and a Triangular Block that Mario must use to climb out of the pit and progress through the level. Mario finds a Question Block on the platform containing a power-up. Next, Mario must get a running start and jump across a pit of lava (with Podoboos in it). The next platform is a long area made of a set of unbreakable gray blocks (and Podoboos and Grinders). Mario jumps across the blocks suspended above the ground, avoiding the Grinders and Podoboos. When Mario reaches the end of the platform and jumps across the lava again, he lands on the last platform of the fortress. If Mario is on the part of the platform at the bottom of the screen, he finds a Triangular Block that helps him climb the wall and reach the boss door. Mario must, again, fight four Reznors on a set of four rotating platforms by hitting the underside of each platform.

Alternate Exit
This exit can only be accessed with Cape Mario. At the last platform in the fortress, Mario must stay on the part at the top of the screen. This way, he will be able to jump onto the row of blocks above the first boss door. When Mario reaches the wide pit of lava, Mario must jump while dashing, activating Cape Mario's gliding ability. If Mario flies far enough without getting hit by a Podoboo, he reaches a secret platform. This platform contains many Rotating Blocks with 1-Up Mushrooms, and the second boss door. In the boss door, Mario has to fight four Reznors again, in the same manner as the normal exit. After completing either exit, Mario will be able to access the Star Road and go to Star World 4.

The alternate exit does not count as a secret exit. As a result, the player is not required to take it to 100% complete the game.
