Northern Thailand Travel Guide: Where to Go, When, and How Long

Northern Thailand at a glance

Sources define the north differently. One counts 17 provinces, including lower-north Tak and Phetchabun. Others center on Chiang Mai and the upper north. This guide uses the upper-north definition, because that is where most first trips are planned, and treats the lower north as an extra tier. Rough Guides notes the climate turns temperate once the train passes the mountains between Uttaradit and Den Chai. Nights can feel downright cold from December to February. Northern Thailand also peaks in the cool months, which makes it a useful counterweight to the beach south.

Which part of northern Thailand fits you

Match the region to your travel style, then check the skip-if line. Rough Guides calls Chiang Mai the capital and transport centre of the north, so it suits almost everyone as a start.

• First-timers: Chiang Mai and Chiang Dao. Skip if you want empty roads.
• Road-trippers: Nan and the eastern loop. Skip if you will not drive or ride.
• Hikers: Doi Khun Tan, Chiang Dao and Mae Hong Son. Skip if you only have a few days.
• Temple seekers: Lampang and Chiang Mai Old City. Skip if you dislike slow towns.
• Families: Chiang Dao, which Travelfish rates well for young children. Skip long loops with small kids.
• Slow travelers: Phrae, Lampang and Nan. Skip if you need nightlife.

Best things to do in northern Thailand, by region

Chiang Mai works as a base. Walk the Old City, ride up to Wat Phra That Doi Suthep and browse Warorot Market. Chiang Dao lies north on route 107, with a cave and trekking. Travelfish suggests 2-3 nights there. Chiang Rai adds Wat Rong Khun and the Baan Dam Museum. North of it, Mae Sai is the border crossing and Sop Ruak is a tour-bus stop. Chiang Saen, with its ruins on the Mekong, is quieter. West of Chiang Mai, the Mae Hong Son loop is scenery-heavy and a long drive. It can loop back through Pai. East of Chiang Mai, Lampang sits about 100 km away. Wat Phra That Lampang Luang is described by Rough Guides as the finest surviving traditional northern architecture. For deeper background, read about Lanna history and temples. Nan is the road-tripper's pick. Tuk Tuk Club describes route 1256 from Pua to Bo Kluea as about 30 km of ridge scenery. Check the road number and condition on a current map. Doi Khun Tan National Park is an easy train-access hike. Rough Guides gives the trail from the station to the summit as 8.3 km, in four quarters of roughly 2 km. Rough Guides also reports a 1,352 m rail tunnel and a 1,373 m summit. Confirm train times with the State Railway of Thailand before you go. A day trip is possible, but overnighting in the bungalows or campsites is more rewarding. If you have extra time, the lower north adds Khao Kho, Phu Thap Boek and Mae Sot toward Umphang. Phu Thap Boek sits at over 1,700 m. For another off-trail region, look at Isan in the northeast.

• Chiang Mai: Old City, Wat Phra That Doi Suthep, Warorot Market
• Chiang Rai: Wat Rong Khun, Baan Dam Museum, Kok River boat trips
• Far north: Mae Sai, Sop Ruak, Chiang Saen
• Eastern towns: Lampang, Phrae, Nan
• Lower north: Khao Kho, Phu Thap Boek, Mae Sot

How to plan your time in northern Thailand

Pick one loop rather than all of them. With 4-5 days, stay around Chiang Mai and add Chiang Dao. With 7-10 days, choose either Chiang Rai or one eastern leg. With 14 days, you can run the full eastern loop. Travelfish routes it as Chiang Mai, Chiang Dao, Phrao, Phayao, Phu Lang Ka, Nan, Phrae, Lampang and back. Its nights, from a 2011 trip, are Chiang Dao 2-3, Phrao 1, Phayao 2, Phrae 1 and Lampang 2. Nan gets the extra days.

Best time to go and the haze caveat

The cool, clear window runs roughly November to February. Travelfish favors December and January, before paddy burning starts. By late February, smoke begins to smolder and builds until the wet season. Check the Thai Meteorological Department for forecasts and use an official air-quality dashboard before booking. Wet season turns the hills green and cheaper, but it is poor for motorbikes. Nan's Lanna boat races usually fall in late October or early November.

• November to February: cool and clear, but crowded
• Late February onward: haze builds, views suffer
• Wet season: green hills, wet roads, fewer visitors

Getting there and around

From Bangkok, you can fly, take the overnight train or go by bus. Tuk Tuk Club puts Chiang Mai at about 1 hour by air. Nan is a little over 1 hour by air from Bangkok. Verify both with airlines. Rough Guides says rail reached Chiang Mai in 1921. Own wheels give the most flexibility. Travelfish says all its eastern-loop roads are sealed and suit intermediate riders. Check license and insurance rules, wear a helmet and avoid riding at night. Buses and songthaews work if you use provincial capitals as hubs. Tours suit the Mae Hong Son loop if you do not drive.

Costs, tickets and opening hours

Our sources give no confirmed 2026 fees for parks, temples or transport. Check the Fine Arts Department for historic sights and the national parks service for park fees.

Where to stay

Choose by base. Chiang Mai offers variety. Chiang Dao suits nature, and Travelfish says the best lodging is a few kilometres out, past the cave. Nan and Lampang have town guesthouses. Rural lodging can be basic, with cold evenings and few shops. A 2011 Travelfish report put the nearest fridge-equipped shop to Phu Lang Ka at 4-5 km. Verify current conditions before you commit.

Responsible travel on hill-tribe treks and elephant visits

Rough Guides raises the exploitative side of ethnological tourism. It also describes elephants that are often poorly treated or overworked. Ask operators who owns the land, how villagers benefit and whether elephants are ridden. Avoid shows and riding. Choose small, independent options in Nan or Chiang Dao instead.

Mistakes to avoid

Trying to cover too much is the main error. Travelfish warns against over-planning. Other traps are listed below.

• Travelling in burning season for views
• Riding at night
• Assuming cold days when nights are the cold part
• Underestimating drive times on mountain roads
• Booking Phu Thap Boek late for New Year
