Macahambus Cave is a scenic tourism attraction that anchors on the Battle of Macahambus on June 4, 1900. This is a significant point in Philippine history as it is regarded as the very first victory of the Filipinos against the Americans at the turn of the 20th century. A marker of the National Historical Institute is placed at the entrance of the cave to commemorate the bravery of the Kagay-anons.

Tourists come here not only to be in the presence of the setting of one of Philippine’s most historic victories but also to take in the breathtaking view of the Cagayan River which flows below the cavern or to observe the formations and bat colonies that rests inside the historic cave.
