Go to Lake Hylia and go to where the Lanayru spirit is located. Turn the opposite direction from the waterfall and walk up the wooden bridge. You will come across an area with another wooden bridge in front of you and three ways to go; left, straight, and right. On your right there’ll be a bridge leading to the cannon man. Go straight and climb a ladder on your left. Now climb up the small ridge on your left to find a small pond. In the middle is a floating box. Pick it up and break it to reveal a fairy inside. Note: The box will reappear with another fairy each time you disappear.
