The Tabon caves are dubbed the “Philippines’ Cradle of Civilization” because some of the oldest human remains found in the Philippines were discovered by Dr. Robert B. Fox, an American anthropologist of the National Museum of the Philippines, on May 28, 1962. The bones date back some 16,500 years.
Today several of the over 200 caves are open to the public (with only about 30 having been explored and documented). Access is by boat, but note that you are required to pre-register at the Tabon Caves Museum where you can also find out more about the history of the caves. You can also arrange a boat and tour guide at the museum.
