Ganon's Tower

For The Legend of Zelda: A Link to the Past on the Super Nintendo (SNES).

Entrance: Death Mountain (Dark World)

What opens it

All seven Crystals: the maidens break the barrier of Ganon's Tower (Death Mountain (Dark World)).

Hocus pocus! You will run into a barrier if you try to enter Ganon's tower.

Link, we are going to break the barrier of Ganon's Tower with our power.

Pits

In 13 rooms here (5F, 3F, 1F, B1), a pit takes one heart from Link in every mail and puts him back at the spot where he came into the room. Pits in the other rooms drop him to the floor below without hurting him.

Spikes

Spike blocks are in 4 rooms here (6F, 4F, 1F). Walking into one takes one heart in every mail and throws Link back. The Magic Cape keeps them from hurting him.

Spike floors are in 4 rooms here (6F, 5F, 3F). Standing on one takes one heart in every mail. The Magic Cape and the ring of the Cane Of Byrna keep it from hurting Link.

From the official guides

Ganon's Tower is the last dungeon. It is bigger than any dungeon so far, with more kinds of monsters and traps. The rooms are not linked in a very complex way, though, so you should reach the top floor more easily than you expect.
