El Nido has been inhabited by humans as early 2680 BC, or even up to 22,000 years ago. This was confirmed by the fossils and burial sites, dating back to the Late Neolithic Age, that can be found in many caves and excavation sites surrounding the municipality, particularly the Ille Cave in New Ibajay. Chinese traders had been regularly visiting the area of El Nido for its edible birds’ nests during the Song Dynasty (960-1279). In fact, El Nido is specifically mentioned in Chinese records as far back 1225. Chau Ju-Kua, a member of the Chinese Royal Family, Trade Commissioner and Superintendent of Customs of the Port of Chuan How wrote about the island, Pa-Lao-Yu or Land of Beautiful Harbors in his book Chu Fan Chi.
