Loei is Thailand’s mountain province in the far north of Isan, where the land folds into sandstone plateaus, the Mekong forms the border with Laos and winter mornings can drop close to freezing on the higher peaks. It is the place Thais go to feel properly cold: to climb Phu Kradueng, to watch a sea of mist roll over the river at Chiang Khan, and to join the masked spirits of the Phi Ta Khon festival in Dan Sai. If you like hiking, slow riverside towns and festivals that feel genuinely local, Loei rewards the long journey.
- Best for: hikers, couples, photographers, slow travellers
- From Bangkok: about 520 km; roughly 8–9 hours by road, or about an hour’s flight to Loei Airport
- Best time: November–February for cool, clear weather and mist; June–July for Phi Ta Khon
- Don’t miss: Phu Kradueng, Chiang Khan’s riverside lanes, sunrise at Phu Thok
Getting there and getting around
Domestic flights link Bangkok’s Don Mueang Airport with Loei Airport, a short ride from town. Overnight and day buses run from Bangkok’s Mo Chit terminal to Loei and Chiang Khan, and many visitors drive, combining Loei with Khon Kaen, Udon Thani or Phetchabun. Distances inside the province are large — Phu Kradueng, Dan Sai and Chiang Khan sit in three different corners — so a rental car or a hired driver makes life much easier. Local songthaews run between the main towns, but services thin out in the afternoon.
Top things to do in Loei
1. Climb Phu Kradueng National Park
Loei’s most famous adventure is the climb onto Phu Kradueng, a heart-shaped plateau of pine forest, meadows and cliff-edge viewpoints. The path from the base is steep — plan on several hours to reach the rim, then a further walk across the top to the main visitor centre — and most people stay at least one night to catch sunrise at Pha Nok Aen and sunset at Pha Lomsak. The park closes every year from June to September; the current season opened on 1 October 2026 and runs to 31 May 2027. Porters at the base can carry your bags for a fee. Map
2. Wander Chiang Khan
This old Mekong trading town is lined with two-storey teak shophouses, many now turned into guesthouses, cafés and craft shops. Evenings bring a walking street along the main lane, and at dawn locals and visitors kneel to offer sticky rice to the monks. Rent a bicycle and follow the riverside path for views across to Laos.

3. Sunrise over the mist at Phu Thok
A short drive from Chiang Khan, the Phu Thok viewpoint is where people gather before dawn in the cool season to watch mist pool in the Mekong valley. Pickup trucks shuttle visitors up from the bottom; bring a warm layer. Map
4. Kaeng Khut Khu rapids
Just downstream of Chiang Khan, the Mekong runs over a broad bed of rocks at Kaeng Khut Khu. In the dry season the river is low and the rocks are exposed; stalls sell grilled river prawns and coconut sweets. Map
5. Phu Ruea National Park
Known as one of the coldest spots in Thailand on winter nights, Phu Ruea has a road almost to the summit, a ship-shaped rock outcrop and wide views towards Laos. It is an easy alternative for travellers who want mountain scenery without a long hike. Map
6. Phra That Si Song Rak, Dan Sai
This whitewashed Lao-style stupa was built in the 16th century to mark a friendship pact between the kingdoms of Ayutthaya and Lan Xang. It is deeply revered; local custom asks visitors not to wear red here. Map
7. Phi Ta Khon Museum at Wat Phon Chai
If you cannot make the festival, the small museum in Dan Sai displays masks carved from coconut-palm bases, costumes and photos explaining the ritual. Map
8. Suan Hin Pha Ngam
Sometimes called “Thailand’s Kunming”, this field of jagged limestone pinnacles in Nong Hin district is explored on guided walks along marked paths. Go early before the heat builds. Map
9. Phu Pa Po
A near-perfect cone-shaped hill nicknamed the “Fuji of Loei”, Phu Pa Po is a popular sunrise and photo spot when the fields around it are green or golden. Map
10. Loei town and the night market
The provincial capital is a practical base with a riverside park on the Loei River and an evening market for cheap Isan dinners before an early mountain start. Map
Suggested two-day itinerary
Day 1: Drive or fly to Loei, continue to Dan Sai for Phra That Si Song Rak and the Phi Ta Khon Museum, then carry on to Chiang Khan for the evening walking street and a riverside dinner. Day 2: Pre-dawn trip to Phu Thok for the mist, morning alms in Chiang Khan, coffee and cycling along the Mekong, then lunch at Kaeng Khut Khu before heading back. Hikers should instead give Phu Kradueng its own two days: climb on day one, sunrise and descent on day two.
Festivals and events in Loei
Phi Ta Khon (Dan Sai), around June–July: Loei’s signature festival, part of the Bun Luang merit-making, fills Dan Sai with dancers in giant painted masks and patchwork costumes. Exact dates are set each year by local spirit mediums, so check with TAT before booking. Cotton Blossom and Red Cross Fair, around December–January: the provincial fair in Loei town celebrates the cool season with parades, crafts and food stalls.

Dates move from year to year — always check with TAT.
Travel tips
- Pack real warm clothes from December to February; mountain nights can be close to 0°C.
- Book Phu Kradueng accommodation and tents ahead for holiday weekends, and start the climb early — the park sets cut-off times for ascents.
- Cover shoulders and knees at temples, and skip red clothing at Phra That Si Song Rak.
- Chiang Khan fills up on cool-season weekends; weekdays are far calmer.
