Location: Barangay Bongtud, Tandag City

Believed to have existed two million years ago, these twin islands do not only serve as natural protector of Tandag from strong typhoons and ysunamis but they are also silent witnesses of the atrocities in the acient times. The big one at the west facing the river and the poblacion was once used by the raiding Muslim Pirates as a vantage point where they would fire thier canons from the southern side of the hill directly to the compound of the solid Royal Fort of Tandag, the main defense of the Spaniards in the region against local rebels and Moro raiders.
