The early inhabitants of the vast forested land were the Kalinga who are indigenous to the Mountain provinces. These settlers lived on tree houses which they built along the banks of the bountiful and mighty Magat River. These sturdy, dark complexioned, G-stringed, soldier-like people depended on hunting, fishing and a little of agriculture and poultry.
The municipality is accessible by land through the major road networks constructed by the national and provincial government and its barangays are accessible through a very good road network constructed by all levels of government.
By air, the municipality can be reached through the nearby Cauayan City airport, about thirty minutes away by a private car or vehicle.
