Pha Taem National Park Review
3,000-Year-Old Rock Art by the Mekong

Pha Taem National Park is a sandstone cliff along the Mekong River at Thailand's easternmost border, in Khong Chiam district, Ubon Ratchathani province. People come here for three things — prehistoric rock art over 3,000 years old stretching along the cliff face by the Mekong, a sunrise viewpoint said to catch the first light in Siam before anywhere else, and Sao Chaliang, mushroom-shaped rock pillars carved by millions of years of erosion. On this page we walk through what you'll actually find there, what reviewers praise, and what to brace yourself for before you go — including the need for a pre-dawn start, strong sun along the cliff walk, and the distance from town, which isn't exactly close.

If you're in Ubon Ratchathani looking for somewhere that doesn't feel like everywhere else, Pha Taem is usually the first name people suggest. It's rare to find two things together in one place — tangible, real historical evidence and a sweeping natural view along the Mekong River. The park sits on a tall cliff running alongside the Mekong, with the land of Laos visible across the water.

Most people come to Pha Taem with the same goal: to walk along the cliff and see rock paintings drawn by prehistoric people more than three thousand years ago, then head up to the rock plateau above for a view of the Mekong. Some plan to stay overnight or arrive before dawn just to watch the sun rise over the horizon on the Laos side. On this page we review the whole experience in depth — both what makes people fall for it and what's worth knowing before you go.

If you visit during the day, the main route is to walk down the stairs from the parking area and along the cliff by the Mekong. The path takes you past clusters of rock paintings made by prehistoric people, showing handprints, human figures, animals like elephants, fish, and turtles, plus geometric patterns. The paint used is a red pigment from ochre soil, and archaeologists estimate the art to be over three thousand years old. The spot most people photograph is a long, continuous stretch of paintings called "Pha Taem," which is where the park gets its name. Thai-English signboards explain the site along the way.

Up top is a wide rock plateau along the cliff edge, where you can look across the Mekong River and clearly see the mountains and villages on the Laos side. This is the reason so many people make a point of arriving while it's still dark, since Pha Taem sits at the easternmost tip of the country, meaning the sun rises here before anywhere else in Thailand. Watching the sun gradually emerge over the ridgeline on the Laos side and spread light across the Mekong is the moment reviewers mention most. Not far away is Sao Chaliang, mushroom-shaped rock pillars formed by wind and water erosion over millions of years, along with fields of wildflowers that bloom in the late rainy season into early winter.

Based on real reviews across several platforms, the things people consistently praise are how much wider the Mekong view is than expected, the peaceful atmosphere, and getting to see genuine rock art that's thousands of years old — an experience that's genuinely hard to find elsewhere. What you should brace for: if you want to catch the sunrise, you'll need to leave your accommodation around 4 or 5 a.m., since the distance from downtown Ubon is around ninety kilometers. The cliffside path gets strong sun and little shade by mid-morning, involves a fair amount of walking, and getting there without a private vehicle is fairly difficult since public transport barely reaches the area.

💡
Tip: If you're planning to catch the sunrise, stay overnight around Khong Chiam or inside the park itself, and check the sunrise time in advance so you have enough time to drive up to the viewpoint before first light. Bring a flashlight and a light jacket (it gets windy on the cliff in the early morning). If you're visiting during the day, bring a hat, sunglasses, drinking water, and comfortable walking shoes, since the cliffside path gets strong sun with no shops along the way.

💡 Know Before You Go to Pha Taem

🌅
Stay nearby if you want the sunrise

Pha Taem is about 90 km from downtown Ubon. If you want to catch the sunrise, stay overnight around Khong Chiam or inside the park, then drive up to the viewpoint before first light — no need to leave downtown at 3 a.m.

🚗
A private vehicle is basically essential

Public transport barely reaches this area, and the park entrance is well off the main road. The easiest way is to drive yourself or rent a car / hire a driver from downtown Ubon, allowing roughly an hour and a half each way.

🧴
Come prepared for cliffside sun

The cliffside path gets strong sun and little shade during the day. Bring a hat, sunglasses, sunscreen, drinking water, and comfortable walking shoes, since you'll be climbing stairs and walking a fair distance.

🎫
Entrance fee and opening hours

There's a park entrance fee, around 40 THB for Thai adults (higher for foreign visitors). Bring cash to pay at the checkpoint, and check the latest opening hours, especially if you plan to enter before dawn for the sunrise.

FAQ

What's the best time of year to visit Pha Taem?

The best weather is in the late rainy season into early winter, roughly November through February, with clear skies, cool breezes, and wildflower fields in bloom — ideal for both the sunrise and the rock art walk. In the hot season, the sun on the rock plateau is very strong, so it's best to avoid midday visits then.

What time do I need to arrive at Pha Taem to catch the sunrise?

You should reach the viewpoint before first light, allowing about half an hour before sunrise. Since Pha Taem is around 90 km from downtown, the most comfortable approach is to stay overnight around Khong Chiam or inside the park, then drive up in the early morning rather than leaving downtown Ubon in the middle of the night.

Can I get to Pha Taem without a private vehicle?

It's fairly difficult, since public transport barely reaches the area and the park itself is well off the main road. The most convenient options are driving yourself, renting a car, or hiring a driver / booking a tour from downtown Ubon Ratchathani. Allow roughly an hour and a half of driving each way.

How much is the entrance fee at Pha Taem?

There's an entrance fee set by the national parks department. Thai adults pay around 40 THB, with reduced rates for children and seniors, while foreign visitors pay more. Parking is charged separately. Bring cash for the checkpoint and check the latest rates before you go.

How long does a visit to Pha Taem take?

If you're just walking the rock art trail and heading up for the cliffside view, plan on about half a day. If you want to cover everything — the sunrise point, Sao Chaliang, and the wildflower fields — allow nearly a full day, or stay one night in the Khong Chiam area.
