The Ghostly Garden is a location from The Legend of Zelda: A Link to the Past. It is the Dark World counterpart of the Graveyard.
Enemies found in the Ghostly Garden include Hinox and Ropas. The area itself has little to do with the overall plot of the game, but Link can use the Magic Mirror here to obtain the Magic Cape in the Light World. If he does not do this, he must wait until he has obtained the Titan's Mitt to reach the Magic Cape.
