This biosphere reserve in the Province of Apayao is divided into two distinct regions: the Upper Apayao sports rugged terrain with towering peaks, plateaus and valleys, whereas the Lower Apayao features flatlands adorned with rolling hills and plateaus. Stretching 180 km, the majestic Apayao River serves as a vital watershed, nurturing 18 tributaries across the province.

yApayaos is a name that encompasses both the people and diverse flora and fauna living in the area. There are various ethnolinguistic groups and ten Indigenous Cultural Communities whose traditions and laws are deeply intertwined with the land and its resources. Notably, the Isnag/Isneg community constitutes 30 percent of the population; it upholds the Lapat system, a unique customary practice regulating the use of natural resources and protection of the environment.

Recognized for its ecological significance, Apayao harbors the Apayao Lowland Forest Key Biodiversity Area, which has high levels of endemism and serves as a refuge for critically endangered species like the Philippine eagle (Pithecophaga jefferyi).

The population of 124 366 engages primarily in rice and corn cultivation. However, ecotourism is progressing in the province. The biosphere reserve spans 3 960 km².
