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. In the beginning of the level, the player will encounter giant wooden pillars and Grinders in a moving screen.

At the end of the first room, there is a midpoint section as well as another door. The player will then encounter more Grinders and Podoboos throughout the level. At the end of the level, there is a large red door that leads to the Reznor bosses. However, if the player climbs over the end-level door and, with a running start, flies with a Cape Feather to the very right end over a large pool of lava full of Podoboos, the player will find many 1-Up Mushrooms inside yellow blocks, as well as another red door that also leads to the Reznors. If the player defeats the Reznors and completes the fortress, they will unlock an entrance to the Star Road, which connects to the level Star World 4.
