Ganon's Tower (The Wind Waker)

Ganon's Tower is located under the Great Sea which used to be Hyrule. After breaking the barrier with the re-charged Master Sword on Hyrule Castle, Link must follow the path from the castle, through a canyon which leads to the tower. There are no barriers stopping Link from accessing the tower. Ganon's Tower in Wind Waker shares some characteristics from the Ocarina of Time version of Ganon's Tower, such as mini-dungeons based off the areas. There are four of these areas, and at the end of each, a black-and-white version of the dungeon's boss must be fought. Gohdan and the Helmaroc King are the only bosses who do not appear as a "Refight" boss. After passing these areas, Link will obtain the Light Arrow and engage Ganon in a final showdown at the top of the tower. In the game's ending, Ganondorf is stabbed with the Master Sword in the head, turning to stone in the process. Afterwards the "walls" that kept the ocean from flowing onto the castle disappear, and Link must escape.
