Overlook Island

In The Wind Waker, Overlook Island is the northeastermost island of the Great Sea. The island consists of tall, interconnected, brick structures with flat, grassy roofs. Palm trees grow on the roofs, convenient targets for Hookshots. Several cannon boats patrol the waters surrounding the island, which will target anyone that attempts to scale the roofs. On the tallest structure is a secret cave housing a Triforce Chart.

By opening the Treasure Chart won in Two-Eye Reef, the Secret Cave Chart can be unveiled from the deep waters surrounding the isle.

Trivia
The Secret Cave found in the island is similar to that from Stone Watcher Island.
