Zora's River

It is possible to make it past the waterfall at the end of Zora's Domain without Zelda's Lullaby, and some of these methods are faster than the Lullaby scene to slow the water anyway.

Method 1 - Cucco

Discovered by YautjaElder

Grab the cucco at the beginning of the river and bring it all the way up to the waterfall. Go to the very left of the closest ledge to the waterfall. Now face the wall sligtly left of the water fall and jump at it. Hug the wall and go a little bit right until you get in the tunnel.

Method 2 - Megaflip

Discovered by ZeldaXMaster

You can do it with a megaflip without the need for the cucco. It's a bit faster but also harder.

Method 3 - Hover Boots

Discovered by ???

As adult simply using the hover boots like the cucco method will do.

Notes

Both the cucco and hover boots methods can be done from the right side, however it's a bit harder and you have to grab the ledge.
