Upper Zora's River

Upper Zora's River is where you have one of your first human fights with the Twilit Messengers and is the location of a Howling Stone. When you defeat the messengers, Iza, the woman with the puffy hair, will thank your heroics by giving you a ride down to Lake Hylia by use of her boat rides. She also asks you while you are paddling down the river to blow up some rocks that are in the way, she will provide the Bomb Arrows.
