Island highlighted.

Four-Eye Reef is one of the 49 islands featured in The Legend of Zelda: The Wind Waker. It is situated at A2 on the game's world map. It's name is derived from the fact that from above there are four circular rocks jutting out of the ground that look somewhat like eyes (or just circles). Surrounding the four "eyes" are walls, though there is an opening at the top of the western wall. Within this section you can find the 19th Treasure Chart and the Great Fairy Chart (which can be found using Treasure Chart #41). The 19th Treasure Chart can be obtained by using your bombs on The King of Red Lions to destroy all of the opposing enemies' boats.
