Balbalasang–Balbalan National Park, also known as Mount Balbalasang National Park, is a protected area in the Philippines. It is located in the municipality of Balbalan, Kalinga, in the Cordillera Administrative Region.

Geography

The park spans 1,338 hectares and is located around Mount Balbalasang in the barangay of the same name, near the provincial border with Abra. Called the "green heart of the Cordillera," the park represents the rich biodiversity and natural beauty of the mountain region, including some of the most well-preserved pine forests and a variety of plants and animals found only in this area. It was established as a national park in 1972 through Republic Act No. 6463.

The park is part of the Luzon Biogeographic Region, a special area where many species are found only in Luzon. It includes two mountain ranges within the Cordillera Central and has many rivers and streams that flow into the Saltan River. Mount Sapocoy is the highest point at 2,456 meters and is located on the western edge of the park, overlooking the Ilocos and Cagayan Valley. The lowest point in the park is at Balbalan, with an elevation of 700 meters, located in the eastern part.

In 2022, Republic Act No. 11688 combined this national park with the Banao watershed to form the Banao Protected Landscape (BPL).

At elevations above 1,000 meters, the park has forests with hardwood trees, pine trees, and mossy vegetation. A type of Rafflesia flower has also been found in the park.

The park is an important place for protecting biodiversity. It is home to 89 bird species, 39 of which are found only in the Philippines. Two of these birds are found only in Luzon: the Isabela oriole and the flame-breasted fruit dove. While no bird species in the park is critically endangered, four are listed as vulnerable according to the 2002 IUCN Red List of Threatened Species. These include the whiskered pitta, Luzon water-redstart, and Luzon jungle flycatcher. The park is designated as an Important Bird Area (IBA) by BirdLife International because it supports a large population of chestnut-faced babblers.

Additionally, 23 mammal species, 13 amphibian species, 13 reptile species, and 25 earthworm species have been recorded in the park. These include the Philippine warty pig, Luzon striped rat, Northern Luzon giant cloud rat, Kalinga narrowmouth toad, and Luzon narrow-mouthed frog. Two mammal species are listed as endangered: the Luzon pygmy fruit bat and the Luzon bushy-tailed cloud rat.
