Mountain Province sits at the heart of the Cordillera Administrative Region in northern Luzon. Its capital, Bontoc, is the traditional home of the Bontoc Igorot — one of the highland peoples whose warrior culture and distinctive cultural practices became known to the outside world during the American colonial period. The province is also the location of rice terraces complementary to the more famous Banaue terraces of Ifugao, and the Chico River carves its way through the highland valleys.
The province is predominantly upland terrain, with the Cordillera mountain ranges creating valleys, gorges, and isolated agricultural terraces. Elevations range from low river valleys to peaks above 2,000 meters. The climate is cooler than the Philippine lowland average, with cold nights and frequent mist in the upper elevations.
Mountain Province has its own rice terraces, in Maligcong, Bontoc, Sagada, and other municipalities. They are not part of the UNESCO World Heritage Site, the Rice Terraces of the Philippine Cordilleras (1995), whose five clusters are all in neighboring Ifugao, but they are farmed the same way and are among the most striking in the Cordillera.
The Chico River rises on Mount Data at the southern edge of the province and flows north through Bontoc and on into Kalinga. The river and its tributaries are the lifelines of the highland communities along its banks. An attempted dam project on the Chico River in the 1970s became one of the most significant indigenous peoples' resistance movements in Philippine history.
The 2024 census counted 149,775 people in Mountain Province, a landlocked province of 2,157 square kilometers. Bontoc is the capital and Bauko the largest municipality, among ten towns in all. It borders Kalinga to the north, Isabela to the east, Ifugao to the south, Benguet to the southwest, Ilocos Sur to the west and Abra to the northwest, and its highest point is Mount Amuyao. The name once belonged to a much larger province created in 1908, which in 1966 was split into Mountain Province, Benguet, Ifugao and Kalinga-Apayao. The main peoples are the Bontoc, the Kankanaey, including the Applai of Sagada and Besao, and the Balangao.
