Zora's Waterfall

In A Link to the Past, this is the home of the Great Zora and it is also the source of the Zora's River.

In Ocarina of Time, Link must play Zelda's Lullaby to get through this waterfall and enter Zora's Domain. This mysterious waterfall is said to be magical. The waterfall can only stop flowing when the King of Hyrule slumbers.
