The Waterfall Rapids, also known as the Fall Headwaters, is a location from The Legend of Zelda: Majora's Mask. It is located at the Zora Hall Coast, just upstream of a large waterfall, and is only accessible to Link through use of the Hookshot. The Beavers reside here and have built a huge dam. It is also where they race opponents for Empty Bottles; Link can participate in races against them while he is in his Zora form. Link may also race them once more for a Piece of Heart. The races consist of swimming through a series of underwater rings, while navigating various obstacles and tunnels. Mikau has apparently raced the Beavers in the past, but could not beat them.
