Wilderness Landscape & Natural Heritage
Phu Khiao Wildlife Sanctuary spans over 2,000 square kilometers in the Chaiyaphum Province of northeastern Thailand. The sanctuary covers mountainous terrain ranging from 300 to nearly 1,000 meters in elevation, featuring evergreen, mixed deciduous, and dry dipterocarp forests. Its terrain includes deep valleys, rivers, and natural grasslands that provide critical habitats for many species. Established in 1972, it is one of Thailand’s oldest and largest wildlife sanctuaries, aimed at protecting the native flora and fauna while helping to stabilize the regional ecosystem. The sanctuary is home to rare mammals such as the Asiatic black bear, Eld's deer, and banteng, as well as a wide variety of bird species, making it a prime area for wildlife research and birdwatchers. Visitors to Phu Khiao can explore several trails that lead through rich forest environments and open meadows, providing opportunities to spot wildlife or enjoy the tranquility of the natural environment. The area is also important culturally, with several nearby villages preserving traditional lifestyles closely linked to the land. While visitor infrastructure is limited to minimize disturbance, basic ranger facilities exist for guidance and permits. The sanctuary’s rugged beauty and rich biodiversity attract adventurous travelers and nature photographers, especially during the dry season when wildlife is more active and accessible.
