The province is drained mainly by the Chico River with headwater originating from Mt. Province and empties into the Cagayan River.The Chico River has several tributaries: Bunog River in Tinglayan in the south, the Tanudan and Biga Rivers in the east, Pasil River in the middle, Mabaca and Saltan Rivers in the north. Several small lakes can also be found in Kalinga. These water resources if to be tapped could provide abundant sources for power generation, fishing, irrigation and for domestic use.
The province enjoys an average temperature ranging from 17 to 22 degrees Celsius and Type III weather patterns. The dry season extends from November to April. The rest of the year is considered rainy. The heaviest rains usually occur in the months of July to October.
A larger portion of the province is open grassland suitable for pasture, but the higher elevation in the west is forested by rich pine trees. Rizal and Tabuk with their flatlands are the biggest rice producers. Next in rice production are the mountainous areas – the rice terraces of Balbalan, Lubuagan, Pasil, Pinukpuk, Tinglayan, and Tanudan.
The people of Kalinga are the most extensive rice farmers of the Cordillera peoples, having been blessed with some of the most suitable land for both wet and dry rice farming. Except for the Ifugaos, the Kalingas are the most extensive terrace builders in the country. The Kalingas are also skilled potters with pot making concentrated in the lower Chico River Valley. They are also excellent in basket and loom weaving and metal works.
