Ubon Ratchathani: Isan’s Emerald Frontier — a 3-Day Itinerary

The itinerary begins with breakfast — and not just any breakfast. Ubon has a deep Vietnamese-heritage food culture stemming from generations of cross-border movement, and Indochine is the city’s most storied expression of it. Nem nuong (grilled pork spring rolls) arrive with a forest of fresh herbs and a dipping sauce that people have been quietly requesting the recipe for since the 1980s. Order one plate and immediately order another.

Ubon’s guardian stupa is modelled on the great Mahabodhi Temple at Bodh Gaya in India — a surprising choice that speaks to the ambition and deep faith of the Isan people who built it. The outer gates are flanked by serpentine nagas of extraordinary craft. Inside, the chedi enshrines relics and is ringed by Buddha images and murals illustrating the life of the Buddha in a style you won’t see anywhere else in Thailand. This is a place of active worship; come quietly and stay as long as you like.

A pause in a whitewashed garden cafe on the edge of town — the kind of place that appears nowhere in any guidebook and gets discovered by word of mouth. The aesthetic is English cottage by way of Isan: fresh flowers everywhere, gentle light, cold-brew coffee made from beans roasted down the road. It is a useful place to remember that not everything in this province announces itself.

Your first proper look at the Mekong. Him’s River sits on a promontory above the water where you can watch the great river slide past between forested banks — on the far side, that is Laos. The menu runs from grilled river fish and punchy Isan salads through to proper coffee; the setting does most of the work. Come before the sun drops behind the hills and stay until dark.

The road out to Khong Chiam district follows the Mun River east toward the Mekong, through rice paddies and small towns that have no reason to dress up for visitors. Saeng Chan — locally called the “falling-into-a-hole” waterfall — is a geological curiosity: the stream drops through a natural hole in the sandstone and emerges as a column of white light in a shadowed chamber below. It photographs strangely, beautifully, and nothing quite prepares you for it. The forest around it is cool and quiet in the morning hours.

Perched on a hillside above the confluence of the Mun and Mekong rivers — the famous “two-coloured river” where the brown Mun meets the green-grey Mekong and the waters run side by side without fully mixing — Memory Cafe has one of the most panoramic views in Isan. The building is open-sided, the coffee is genuine, and the kitchen produces food worth lingering over. Take a long table on the terrace and watch river traffic pass far below.

On a ridge above the Mekong, this temple has earned the name “Wat Rueang Saeng” — the Glowing Temple — for a reason nobody fully explains in advance: after dark, the Kalpaphruek trees planted around the ordination hall begin to phosphoresce, emitting a soft, cold green light from their bark and roots. The effect is somewhere between miracle and hallucination. The temple also commands a panoramic view of the Mekong and the Lao hills; our guide knows when the bioluminescence is most visible (roughly 6 to 7:30pm) and will time the visit accordingly.

The alarm is worth it. Pha Taem is a long sandstone escarpment dropping sheer to the Mekong, and the most easterly point in Thailand — meaning the first place in the country where the sun rises each year. The cliff face carries ochre paintings made by Bronze Age people some 3,000 years ago: fish, turtles, human figures, and geometric patterns rendered at a scale that suggests ceremony rather than casual mark-making. No other country’s border is quite like this: standing here, looking across the brown water at Laos, with ancient paintings at your back and the morning fog still lifting off the river, is among the most quietly affecting things you can do in Thailand.

The Mekong recedes every dry season to reveal an extraordinary moonscape: more than three thousand natural rock pools and hollows carved by the current over millennia into the riverbed sandstone. Each pool catches the light differently; together they create something that looks closer to another planet than to a riverbank in Isan. This is also, improbably, where the K-pop star Lisa filmed a sequence that went viral — which is the least interesting thing about it, but explains why you may recognise the photographs. Visit in the dry season (November through May) when the pools are fully exposed.

The drive back to Ubon gives time to stop at a roadside market for Isan provisions — fermented fish paste wrapped in banana leaf, sticky rice in woven bamboo, dried chillies in quantities that require explanation at customs. Your flight home is typically late afternoon; or we can continue north to extend the journey.
