Upper Zora's River

Upper Zora's River is the location of the first fight with Shadow Beasts while in human form, and is the location of a Howling Stone. When you defeat the messengers, Iza, the owner of the boat rentals shop, 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, as she will provide the Bomb Arrows.
