Wander around Coastal Highway or any area with a fishing hut. Have your best clothing and items to make a fire, except for the wood itself. You will also require food, water, and also fishing equipment. Go to the fishing hut and begin to gather firewood. Place a fireplace directly in front of the fishing hut's entrance and light it. Put in all the gathered firewood so the fire will burn for at least eleven hours. If desired, sleep or try to get some fish out of the hole. Get more firewood and add it to the fire when you have the time. You can take out your sleeping bag and rest for twelve hours. Repeat the process until "Beneath a Starry Sky" is earned.

Enter every structure with a loading screen in Mystery Lake and Coastal Highway. This includes every vehicle and building except for ruins, lookouts and fishing huts.
