About Pha Taem National Park#

Pha Taem National Park is a protected area in Ubon Ratchathani province in northeastern Thailand, noted for its prehistoric rock paintings and dramatic sandstone cliffs. The site is set on a high escarpment that overlooks the Mekong River and the Lao border.

The park’s main highlight is a series of ancient pictographs painted on a cliff face, showing humans, animals and boats; panels extend along the rock and are accessible by a short walk from the parking area. The cliff-top viewpoint offers wide panoramas across the Mekong and is a popular spot for sunrise and sunset.

Archaeological surveys have shown the pictographs date back several thousand years and are among the most significant prehistoric rock-art sites in Thailand. The area has been managed as a national park to protect the paintings, the cliff environment and surrounding forested plateau.

Pha Taem sits on the Mekong frontier in easternmost Ubon Ratchathani province, on a sandstone plateau that drops steeply to the river and the Laos bank. The park is accessed by road from the provincial network and sits close to the Thailand-Laos border.

  • Age of paintings: The cliff-face pictographs include stylised human and animal figures and boats and have been dated to several thousand years old by archaeologists.
  • Best time to visit: Early morning and late afternoon light give the best viewing conditions for the cliff panels and river views; the dry season offers clearer visibility.

What to See#

  • Cliff paintings: Rock-art cliff panels on sandstone escarpments with painted figures of humans, animals and boats; panels are visible on a prominent cliff that overlooks the Mekong.
  • Pha Taem viewpoint: A cliff-top viewpoint that provides wide views across the Mekong River to Laos and is prized for sunrise and sunset photography.

How to Get to Pha Taem National Park#

Pha Taem National Park is in Ubon Ratchathani Province near the Lao border. From Ubon Ratchathani city, drive east along Route 232 to the park - the trip is several hours by car. Local buses and organized tours run from the city during high season.

Tips for Visiting Pha Taem National Park#

  • Arrive before dawn to watch the Mekong plain and Laos across the river light up - the park's cliff-top viewpoints are dramatic at sunrise
  • Bring insect repellent and a hat-the trails along the cliff edge are exposed and summer mosquitoes can be persistent
  • Hire a local boat to see the Mekong and the prehistoric rock art from river level if water levels allow
