Phantom Hourglass Treasure Maps
Below is a listing of all 31 Treasure Maps that Link finds on his quest, along with the locations and contents of their corresponding Sunken Treasure. Treasure Maps are a great way for Link to acquire Ship Parts as well as Sand of Hours. In addition to the 31 Treasure Maps, Link can also discover a Sunken Treasure by sinking a large Pirate Ship, which triggers an X to appear on the location of the map.
