Pha Taem National Park

Pha Taem National Park is a protected area in Khong Chiam District, Ubon Ratchathani Province, eastern Thailand, along the Mekong River bordering Laos. Established in 1991, it covers about 340 square kilometers of dipterocarp forest, sandstone cliffs and plateaus. It is notable for extensive prehistoric rock paintings dating back 3,000 years, dramatic cliff viewpoints, and unusual mushroom-shaped rock formations such as Sao Chaliang.

Visitors can expect a sandstone plateau and cliff-top park overlooking the Mekong River with panoramic views into Laos. The main area includes a cliff walkway with viewpoints, a 3-4 km trail along prehistoric rock paintings sheltered under the cliff, dipterocarp forest, and distinctive mushroom-shaped pillars at Sao Chaliang. Facilities include a visitor centre, marked nature trails, viewpoints for sunrise, and seasonal waterfalls such as Soi Sawan and Saeng Chan.
