Remember that your task is to collect 20 arrows. Head left from the signpost to Mikau Lake and swim up the waterfalls to Lulu Lake, and again up to Ploymus Mountain.
When you’re ready, leave through the East Gate by way of the second floor bridge.
Before leaving, be sure to talk to the Zora Laflat who has a related quest to take a picture of the menacing red-maned Lynel.
