Situated in Barangay Tandang Kutyo of Tanay, Rizal, Calinawan Cave is an enormous cave system composed of multiple levels and various chambers and openings. History tells us that the cave served as hideout by Filipino revolutionaries during Spanish-American war, and a shelter during the Second World War. How it got its name, according to local folklore, has a touch of history too, as it was where the Japanese and American troops settle their disputes, thus Calinawan from the Filipino word “linaw” which means to settle or to clear.
