The thickly jungled Babeldaob, the largest island in Micronesia after Guam, has a land area of over 150 sq miles (400 sq km), more than four times the total area of all the other islands put together. Still, its population is small, as most young people make their way to Koror in search of jobs. Babeldaob's Melekeok State was designated in the constitution as the future site of the country's capital, and although grandiose plans have been drawn up, many people doubt they'll ever come to fruition. Babeldaob is a high, volcanic island of gently rolling hills, with beautiful stretches of sandy beach on the east coast and mangrove forests on the west. Parts of the jungle are virtually unexplored, and many of the villages are still connected by ancient stone paths. Many of the island's hillsides were once terraced into steps and pyramids; archeological research suggests they were probably begun around 100 AD. Their purpose remains a mystery. Ngarchelong State, at the northernmost end of the island, has an open field with rows of large basalt monoliths known as Badrulchau, placed there according to legend by the gods to support an enormous bai. Airai, at the southern end of the island, has Palau's international airport. The town's most visited attractions are its two bais, one old and one new. The northern Ngaraard State has some of the island's prettiest beaches. A village tour of Babeldaob is where visitors can see some of the impressive historic and cultural sites such as stone walkways and hedges of immense sizes, plus the Palauan equivalent of the Biblical Lot story - an ancient statue of a mother and child who were turned to stone when the mother peeked inside a village men's house. Overnight accommodation here is not available so visitors can ask to stay with a family.
