Skeleton Forest is a location from The Legend of Zelda: A Link to the Past. This large forest is located in the northwestern region of the Dark World and is the Dark World's equivalent of the Lost Woods. Unlike the Lost Woods, however, all of the trees are the grim Dark World trees, and instead of logs are the spines of massive creatures.
Skull Woods, the third Dark World dungeon that Link encounters in his quest to rescue the Seven Maidens, can be found here. The dungeon's main treasure is the Fire Rod, and its boss is Mothula. Interestingly, the dungeon has several entrances above ground.
