We have been sending private groups to Ubon Ratchathani for years. In all that time, we have met precisely one other foreign-run tour company doing the same. That says something. Not about the destination — Ubon is outstanding — but about the blind spots in how most people think about Thailand.
Most visitors to Isan go to Chiang Rai (wrong region, but the confusion is real), maybe Khao Yai, occasionally Khon Kaen for a business trip. Ubon, which sits at the far southeastern corner of Isan almost exactly where Thailand, Laos, and Cambodia converge, simply doesn't appear on the usual travel radar. That is the entire reason to go.
Why Ubon Matters
Geography shaped this city in ways that still show. Standing on the cliffs of Pha Taem, you look east across the Mekong into Laos. Drive an hour south and you're at the Cambodian border. This triple-frontier position made Ubon a crossroads for centuries — of Lao, Khmer, and central Thai cultural currents, all of which left marks on the temples, the food, and the spoken dialect you hear at the morning market.
The Lao-Buddhist influence is especially vivid. The temple murals here tend toward the flatter, more graphic style you see in Luang Prabang — different from the ornate gilded aesthetic of Bangkok's royal temples. The city has a university, a modest international airport, and a civic pride that doesn't perform itself for outsiders. It is, in the best sense, a city living its own life.
For visitors interested in Isan as a region, Ubon is the natural eastern anchor — a counterpart to Khon Kaen in the west and Udon Thani in the north.
The Candle Festival: One of Thailand's Most Underattended Great Events
If your dates are even remotely flexible and you're planning a trip to Thailand in late July or early August, rearrange your schedule around Ubon's Candle Festival (Ngaan Hae Thian Phansa). We say this with seventeen years of experience behind the claim: it is one of the genuinely great spectacles in Southeast Asia, and it draws almost no foreign visitors.
The festival marks the start of Buddhist Lent (Wan Khao Phansa), the three-month rains retreat during which monks remain inside their monasteries. The tradition across Thailand is for laypeople to present candles to the temples. In Ubon, this custom evolved into something extraordinary. Temples and civic groups spend the months before the festival carving massive sculptures from beeswax — some standing four or five metres tall — depicting scenes from Buddhist mythology, the Ramakien epic, and Isan folk stories. The detail is astonishing: individual scales on a naga serpent, the folds of a celestial robe, the face of the Buddha rendered in warm amber wax.
On the festival day, these sculptures are loaded onto ornate floats and paraded through the city centre in a procession that lasts most of the day. Afterwards they're installed at their respective temples for the three months of the Retreat. The whole event is free. Crowds are Thai-majority. English explanations are sparse. It is as authentic as anything we have ever witnessed.
Wat Phra That Nong Bua
This is the temple that stops first-time visitors in their tracks. The central chedi — the white, corn-cob-shaped stupa — is modelled after the Mahabodhi Temple in Bodh Gaya, India, the site of the Buddha's enlightenment. This architectural style (called Mahabodhi or Sri Lankan after its route of transmission) is rare in Thailand. Bangkok has nothing like it. Chiang Mai has nothing like it. Finding it in a provincial Isan city is a genuine surprise.
The surrounding grounds are peaceful and usually uncrowded. The chedi's four sides are decorated with stucco reliefs depicting Jataka tales — stories of the Buddha's previous lives. Set aside an unhurried hour here, ideally in the cool of early morning.
Pha Taem National Park: Prehistoric Art and the Mekong
About ninety kilometres northeast of the city, Pha Taem is one of those places that makes you feel the deep antiquity of human presence in Southeast Asia. The cliff faces here carry rock paintings estimated to be three thousand to four thousand years old: fish traps, hand prints, fish, giant catfish, elephants, and human figures painted in red ochre by the people who lived along this stretch of the Mekong before written history.
But even setting the art aside — the location is extraordinary. The sandstone cliffs drop straight to the Mekong. Laos lies on the far bank. In the dry season the river is a pale jade-green. At sunrise, the light comes from across Laos and strikes the cliff face horizontally. We have watched that sunrise with guests who have travelled on five continents, and all of them went quiet.
The park also has unusual mushroom-shaped rock formations (Sao Chaliang) eroded from the sandstone — strange, almost lunar formations that photograph beautifully in the late afternoon.
Kaeng Tana National Park
Smaller and quieter than Pha Taem, Kaeng Tana sits where the Moon River meets its gorge before joining the Mekong. The landscape is gentle rather than dramatic: low rapids braiding through sandstone outcrops, dry dipterocarp forest, and a birdlife that rewards patience. The park is excellent for birders — the forest-riverine edge habitat here hosts species you won't see on a standard central Thailand itinerary. For guests who want a half-day of genuine quiet without major exertion, this is where we send them.
The Food: Eating the Real Isan
Isan food in Bangkok is a simplified, sometimes sweetened version of itself. In Ubon, you eat the original. The morning market on Ratchabut Road starts before dawn and is finished by 8am; it is the most efficient way to eat three entirely different dishes by 7am.
The essentials: sai krok Isan, the fermented pork sausage with fresh ginger and raw cabbage to cut the sour funk. Gai yang, the grilled chicken marinated in lemongrass, galangal, and coriander root — the Ubon version is noticeably smokier than the Chiang Mai equivalent. Khao niao, the glutinous sticky rice that anchors every Isan meal, eaten by pulling off a small ball with your right hand and using it to scoop up whatever else is on the table. Watching someone eat sticky rice properly is like watching a different relationship with food.
For a more structured dinner, the riverside area near Wat Jaeng has several local restaurants where families bring their children on Friday evenings and the kitchen closes when the food runs out.
Getting There: Easier Than You Think
Ubon Ratchathani Airport (UBP) is served daily from both Bangkok Suvarnabhumi and Don Mueang. Thai AirAsia and Nok Air each run multiple flights; the journey is about an hour. Budget fares on advance booking are reasonable. There is genuinely no reason to treat Ubon as a difficult destination.
The State Railway does run overnight sleeper trains from Bangkok Hua Lamphong (around 9–11 hours, arriving early morning). If you have the time and want the experience of waking up in provincial Thailand, arriving by train is worth it once. But it is not a prerequisite. The city rewards the time you spend in it — getting there is just the logistics.
We typically recommend a three-day itinerary anchored in Ubon for guests who want a genuine Isan experience without the travel fatigue of trying to do too much. Three days allows for both national parks, the main temples, good market time, and at least one evening of doing nothing in particular — which, in Ubon, turns out to be surprisingly pleasant.
