Phu Sa Dok Bua National Park

Phu Sa Dok Bua National Park is a protected sandstone plateau park covering 231 sq km across Yasothon, Amnat Charoen and Mukdahan provinces in northeastern Thailand. Established in 1992 as Thailand's 75th national park, it is notable for its dry dipterocarp and mixed deciduous forests, sandstone cliffs, seasonal lotus-filled ponds that give the park its name, and viewpoints such as Phu Sa Dok Bua and Phu Tham Phra.

Visitors can expect a quiet, forested sandstone plateau with undulating hills, rocky outcrops, and seasonal natural ponds with lotus blooms. The park offers forested hiking trails, scenic viewpoints over the Isan plain, sandstone cliffs and caves such as Phu Tham Phra, and areas for nature study and camping. Facilities are basic and focused on nature-based recreation, with a visitor centre and campsite near the park headquarters.
