Phu Phan National Park

Phu Phan National Park is a protected forest park spanning the Phu Phan mountain range across Kalasin and Sakon Nakhon provinces in northeastern Thailand. The Somdet District section in Kalasin provides access to sandstone plateaus, mixed deciduous and dry dipterocarp forests, waterfalls and viewpoints. Established in 1988, the park covers about 664 square kilometres and is notable for its natural landscapes, hiking trails, wildlife and seasonal waterfalls.

Visitors can expect a forested mountain landscape with sandstone cliffs, plateaus and viewpoints over the Isan plateau. The park offers nature trails through deciduous forest, seasonal waterfalls such as Tang Pee Parn, wildlife and birdwatching opportunities, and designated camping and picnic areas. Facilities are centered at the park headquarters and viewpoint areas, with bungalows and campsites available for overnight stays.

Established on 7 November 1988 as Thailand's 10th national park, Phu Phan National Park protects approximately 664 square kilometres of the Phu Phan Range. The range has long served as a natural watershed and forested highland between the Sakon Nakhon and Kalasin basins.

The park lies within the Isan cultural region and preserves forested landscapes traditionally used by local communities. The broader Phu Phan area is known for its association with local forest traditions and as a natural landmark of northeastern Thailand.
