Itbayat Island

Geography and Ancient History

Itbayat is an uplifted coral limestone island characterized by rolling interior pastures, deep caverns, subterranean rivers, and dense forests.

Archaeological digs led by the National Museum of the Philippines indicate that Itbayat served as the initial landing site for Austronesian seafaring migrants arriving from Taiwan around 4,000 BP (Before Present). The islanders speak Itbayaten, a distinct dialect of the Ivatan language.
