Chiang Khan is a small town of old teak houses on the Thai bank of the Mekong in Loei province, in the far north of Isaan. Thai visitors come for the riverside walking street, the morning alms round and the sunrise over the mist from Phu Thok; hikers come to Loei for Phu Kradueng, a flat-topped mountain that is open to climbers from October to May.
Loei is one of the least-visited provinces in Thailand by foreign travelers, which is part of its appeal. It is hillier and cooler than the rest of Isaan, and in the cool season the nights can be cold enough for a jacket. This guide covers Chiang Khan itself, the riverside sights near town, the climb up Phu Kradueng and how to get there by air, train and bus.

Chiang Khan: teak houses on the Mekong
Chiang Khan was once an important crossing point into Laos. Today it is a quiet town strung along the river, and its main street, Chai Khong Road, runs parallel to the Mekong. TAT describes it as lined with teakwood hotels and houses in an Indochinese style, and many of the old houses now take guests.
Things liven up in the evening, when a popular night market fills Chai Khong Road with snacks, handicrafts and souvenirs. We found no official hours, and Thai holiday weekends can be crowded. In the early morning the town is calm again. TAT's advice is to stay in a homestay or one of the teak hotels overlooking the river, where you can have a drink at sundown and look across to Laos.
Chiang Khan has also had international attention for how it handles tourism. In March 2026 a story from the town, "When the Mekong Changed: A Fishing Village's Journey Towards Sustainable Tourism", submitted by Thailand's Designated Areas for Sustainable Tourism Administration (DASTA), won a Green Destinations Story Award at ITB Berlin.
The morning alms round
Early each morning, monks walk through the town to receive food from residents and visitors. In Chiang Khan this has become one of the best-known sights, and TAT lists making merit with the monks among the things to do. If you want to give, ask your guesthouse the evening before where to buy food for the offering and where to wait.
If you take part, do it quietly and respectfully: dress modestly, never touch a monk, and do not use flash or block the line for a photo. Our page on temple etiquette explains the dress code, and our article on monks in Thai daily life explains what the alms round means.
Offer only food you would eat yourself. The alms round is a religious act, not a show. If you do not want to give, watching from across the street is fine, but stay quiet and keep a respectful distance from the monks.
Phu Thok: sunrise over the mist
Phu Thok is a hill near Chiang Khan known for its view of the sunrise over the town and the river. TAT lists the "spectacular sight of Phu Thok" and the panoramic sunrise among the things to do in Chiang Khan.
We could not find an official page with the opening time, access rules or any fee. Ask your guesthouse the evening before how to get there: you need transport arranged in town and an early start to arrive before sunrise. Our guide to songthaews explains how to hire one. Bring a warm layer, because cool-season mornings in Loei can be cold.
Kaeng Khut Khu and the river villages
Outside town, the river bends sharply at Kaeng Khut Khu, where, according to TAT, the low water from November to May exposes sandbanks, rapids and colored boulders that are under water the rest of the year. Locals come at sunset to look across to the hills of Chana Kham in Laos and to eat grilled fish and spicy salads at the stalls on the bank. You can also hire a boat for a trip on the river.
The Chiang Khan district has other village visits. At Ban Pa Na Nat, TAT says, the Tai Dam community, whose families came from northern Vietnam by way of Laos, has kept its houses, weaving and dances. In May, the village of Ban Na Sao holds the Phi Khon Nam ghost festival, which in 2026 ran from 2 to 4 May during the Bun Duean Hok merit-making. Do not confuse it with the better-known Phi Ta Khon festival, which is held in Dan Sai district (20 to 22 June in 2026).
To follow the river further, the road east along the Mekong leads towards Nong Khai; our sister site has a route guide to the Mekong river road for drivers.
Phu Kradueng: the climb to the plateau
Phu Kradueng National Park protects a flat-topped mountain with a broad plateau, cliffs and waterfalls on top. The climb up is long and steep, and many visitors stay a night on the plateau, not least because the guided sunrise walk starts at 05:00. It is a Category 2 park: 200 baht for foreign adults and 100 baht for children.
The summit is open only part of the year. For the 2026–27 season, hiking and overnight stays run from Thursday 1 October 2026 to Monday 31 May 2027, and the top is closed every year from June to September, in the rainy season. The park admits up to 3,500 visitors a day, and about 350 registered on opening day this year, according to the Thai press quoting the park.
| Phu Kradueng rule (2026–27 season) | Time |
|---|---|
| Start the climb up | 06:00–12:00 |
| Climb down | Within 07:00–13:00 |
| Cliff zone on the plateau | From 08:00; leave Pha Lom Sak by 18:00 |
| Phairat–Thanchai reservoir | 06:30–17:00 |
| Tham Yai waterfall | 08:30–14:00 |
| Pha Nok Aen sunrise (guided only, once a day) | 05:00–07:00; meet at Wang Kwang visitor center at 05:00 |
Plan your day around the start window: if you reach the trailhead after midday, you will not be allowed up. Porters carry bags to the top for a fee, but we found no current official rate, so ask at the foot of the trail. Wear proper shoes, carry water, and bring warm clothes if you stay a night on the mountain.
Do not plan a Phu Kradueng climb between June and September. The summit is closed every rainy season. In 2026 the park opened on 1 October; check the park's notices for the 2027 closing and reopening dates before you book.
More of Loei: reservoirs, mountains and Dan Sai
With a car, Loei has more than enough for a week. TAT recommends Huai Krathing reservoir, where you can rent a floating bamboo raft and spend an afternoon on the water; Phu Ho, a mountain whose shape is often compared to Mount Fuji, with walks on nearby Phu Pa Po; and the limestone formations of Suan Hin Pha Ngam. In Dan Sai, besides the Phi Ta Khon festival, Wat Neramit Wipatsana is a laterite temple with murals of the Buddha's life set in green hills.
Loei also had local flash floods in early October 2026 around Wang Saphung district; the water had gone down by 6 October. Heavy rain can affect mountain roads in the province, so check before a long drive.
Getting to Chiang Khan and Loei
By air. Thai AirAsia flies from Don Mueang to Loei Airport (LOE). Our guide to domestic flights in Thailand covers baggage rules. From the airport, arrange a transfer to Chiang Khan with your guesthouse or rent a car.
By train and bus. There is no railway to Loei. The nearest station is Udon Thani, about 150 km east, which has an overnight sleeper from Bangkok; our Udon Thani guide lists the trains, and our page on Thailand's night trains compares the berths. From Udon, buses run on to Loei.
By bus from Bangkok. Buses to Loei leave from Bangkok's Northern Bus Terminal (Mo Chit 2), according to TAT, and the coach company Sombat Tour lists Loei in its booking system. From Loei town you continue to Chiang Khan by road: ask at the bus station about local services, or arrange a transfer with your guesthouse. Our guide to long-distance buses explains the classes.
Chiang Khan fits well into a longer Isaan route. The Isaan guide gives the overview of the region, and our page on Nong Khai and the Mekong covers the Friendship Bridge and day trips to Vientiane, which Chiang Khan does not offer.
When to go
The cool season from mid-October to February is the best time, and TAT notes that it is also the most popular time to hike, so book ahead for weekends and public holidays, or come on weekdays. Our page on Thai public holidays lists the long weekends to avoid. September is the wettest month, and from June to September Phu Kradueng's summit is closed.
