Nong Khai is a relaxed Mekong river town facing Vientiane, the capital of Laos, across the water. Its riverside promenade, Indochina market and laid-back guesthouses make it one of the most pleasant places in Isan to slow down, while the province also holds some of Thailand’s most surprising sights: a garden of giant concrete sculptures, a glass skywalk over the Mekong, and the mysterious Naga fireballs that rise from the river at the end of Buddhist Lent. It is also the main road and rail gateway to Laos via the First Thai–Lao Friendship Bridge.
- Best for: slow travellers, couples, culture lovers, overland travellers to Laos
- From Bangkok: about 615 km; roughly 8–9 hours by road or an overnight train; or fly to Udon Thani (about an hour from Nong Khai)
- Best time: November–February for cool weather; October for the Naga fireballs
- Don’t miss: Sala Kaew Ku, Wat Pho Chai, the riverside at sunset
Getting there and getting around
The nearest airport is Udon Thani, about an hour away by road; shuttle vans and taxis connect the two. Nong Khai is the terminus of the Northeastern railway line, and buses run from Bangkok’s Mo Chit. In town, bicycles, tuk-tuks and songthaews are enough for the riverside and temples; for Wat Pha Tak Suea, Phon Phisai or Si Chiang Mai you will want a car or motorbike. The Friendship Bridge to Laos is just west of town — check current border and visa rules before crossing.
Top things to do in Nong Khai
1. Sala Kaew Ku
A sculpture park filled with towering concrete figures of Buddhas, Hindu gods and nagas, created by the mystic Bunleua Sulilat. The seven-headed naga sheltering a meditating Buddha is the star; the main building holds more art and the founder’s preserved remains. Map
2. Wat Pho Chai
Home to Luang Pho Phra Sai, a revered gold Lao-style Buddha image brought from Laos, and murals telling the story of its journey across the Mekong. It is the province’s most important temple. Map
3. Riverside promenade and Tha Sadet Market
The promenade along the Mekong is perfect for an evening walk or bike ride, with views across to Laos. Tha Sadet Market (the “Indochina market”) sells snacks, clothes and goods from Laos, Vietnam and China. Map
4. Phra That Nong Khai
An ancient Lao chedi that slid into the Mekong as the riverbank eroded; in the dry season, when the water is low, its top can be seen above the river. Map
5. Wat Pha Tak Suea skywalk
In Sangkhom district, this hilltop temple has a glass-floored skywalk hanging over the cliff, with sweeping views of the Mekong and the Laos hills. Visitors usually wear cloth shoe covers on the glass. Map
6. Wat Hin Mak Peng
A peaceful forest temple on rocky ground above the river in Si Chiang Mai district, known for its strict monastic tradition — dress modestly. Map
7. Phon Phisai and the Naga fireballs
At the end of Buddhist Lent, on the full moon of the 11th lunar month (usually October), crowds gather along the Mekong at Phon Phisai and elsewhere to watch glowing balls rise silently from the river — a phenomenon locals attribute to the Naga. Map
8. Wat Phra That Bang Phuan
A historic temple with a tall Lao-style stupa, ruined old chedis and a calm atmosphere, south of town towards Udon. Map
9. The First Thai–Lao Friendship Bridge
Opened in 1994, the bridge carries road and rail traffic to Vientiane. Even if you are not crossing, the riverside nearby is a good spot to watch the Mekong. Map
10. Sangkhom and the Mekong road
Route 211 west of town follows the river through Si Chiang Mai and Sangkhom, with small villages, waterfalls and riverside guesthouses. Map
Suggested two-day itinerary
Day 1: Morning at Wat Pho Chai, then Sala Kaew Ku before the midday heat; afternoon at Tha Sadet Market and a sunset walk or ride along the promenade, finishing with a riverside dinner. Day 2: Drive west along the Mekong road to Wat Hin Mak Peng and the Wat Pha Tak Suea skywalk, lunch in Sangkhom, and return in the evening — or cross the bridge for a day in Vientiane if you have the right documents.
Festivals and events in Nong Khai
Ok Phansa and the Naga fireballs (usually October): the province’s biggest event, with boat processions, illuminated boats and riverside crowds; book accommodation early. Songkran (13–15 April): Luang Pho Phra Sai is traditionally carried in procession so people can pour water in blessing, alongside water play along the riverside; read our Songkran etiquette and survival guide. Long-boat races: held on the Mekong in the rainy-season end period. Dates vary — check with TAT.
On King Taksin’s trail
