Palawan is composed of the long and narrow Palawan Island, plus a number of other smaller islands surrounding the main island. The Calamianes Group of Islands, to the northwest consists of Busuanga Island, Culion Island, and Coron Island.
Durangan Island almost touches the westernmost part of Palawan Island, while Balabac Island is located off the southern tip, separated from Borneo by the Balabac Strait. In addition, Palawan covers the Cuyo Islands in the Sulu Sea. The disputed Spratly Islands, located a few hundred kilometers to the west is considered part of Palawan by the Philippines, and is locally called the Kalayaan Group of Islands.
