Morotai is the northernmost Island of Maluku and is rugged, deeply forested and rarely visited. There are many coastal villages around the Island and most of them can only be reached by sea. Daruba is the islands largest town and a paved road leads up the East coast as far as Berebere. Many beautiful islands and islets are located off the south-west coast and provide for some interesting cruising grounds. There are some good diving locations around the island as well as some world class surfing spots along the North and East shores.
Morotai played a major role during WWII and is perhaps most famous as the Allied base during from where General MacArthur launched his assault against the Empire of Japan.
