The Third Island is volcano island and the beach is south volcano beach. To get There you need to find one of the ancient pier I think on west beach, then craft a canoe to get to volcano island.
Then find the rest of your crew (that is if you created 6)when you reach the island. Then find all those Hieroglyphic ancinet steele to enter the llama temple, (put all nine of them in there) but before you do that pause the game and buy a hardwood or bambo bench and craft the hieroglyphic Steele. After you do that stand in front of the llama temple door they are the big black hard steel doors. Put the steele in the door and your in. Now what else? Fish a shark.(you can get there from the island map on the pause menu or dive from the llama ancient theater Cliff) go to the tidal pool with a hardwood or bambo fishing pole and fish a shark *Tip*: your sim will fill a jerk on the pole that will let you know that they've fish a shark usually in the tidal pool you will catch Tiger Sharks.
Next find all the treasure map pieces there are nine of them. And trt to find beard beard the pirate's treasure chest, I didn't find it yet but it's worth a try. Did I leave any else out? Oh yeah you can craft a boat I forgot what it's called but your sim(s) can get home like that it's on North Volcano beach close to the tidal pool. You will see an ancient pier. You can also live on the third island. The best to places are geyser plains and volcano overlook. I think volcano overlook is better because it has more room. But what's bad about is that you live by the volcano as in the volcano is up there and your do here. That's all I know but that should help you will the island.
