How to Go to Bantayan Island

Bantayan Island, about 136 kilometers from Cebu City, got its name in the 1600s when watchtowers (locally known as "bantayan sa hari") were built to protect the islands from the Moros. 
Bantayan Island is frequented by visitors for its quiet beaches. It gets swarmed every Holy Week that locals joke the island tilts on its side this time of year.
