Ganon’s Castle, the final obstacle between Link and his showdown with Ganondorf, is expected to be the most challenging and oppressive locale in all of Ocarina of Time. Unfortunately the developers only left a single recovery heart in this, but it's worth stopping by just to say you’ve explored all the water and lavafalls the game has to offer. Simply jump, toward the lava and you will pass through into a small room on the other side. Located in the arena where you first do battle with the two Lizalfos, this secret is hidden behind a lavafall in the southeast corner of the room.
