Calinawan Cave got its name from the word "linaw" a Tagalog term for clear. It is said that during the 15th-18th century, opposing parties used to convene inside the cave to settle disputes - thus the name Calinawan came about.

This cave also served as a shelter and a hideaway from the Japanese during World War II. It was also in this cave that the Japanese sodiers surrendered to the Liberation Forces.
