Babeldaob is the largest island in the island nation of the Republic of Palau. It is in the western Caroline Islands, and the second largest island in the Micronesia region of Oceania. Palau's capital, Ngerulmud, is located on Babeldaob, in Melekeok State.
Unlike most of the islands of Palau, Babeldaob is mountainous. It contains Palau's highest point, the 242 m (794 ft)-tall Mount Ngerchelchuus. Babeldaob's eastern coast has many sandy beaches, in particular north from Melekeok to Ngaraard, and the island's western coast has a shoreline with many mangrove forests
