Northern Thailand, also called Lan Na, is a region of mountain ranges and river valleys in the top half of the country. Its higher elevation and latitude bring cooler winters and wider seasonal temperature swings than the rest of Thailand. The name comes from the Lanna Kingdom, which took shape in the 13th century and lasted until the 18th. Its roots reach back further, to the Hariphunchai Kingdom, a powerful state in the region in the 7th century. The temples of Chiang Mai, the old Lanna capital, show that history most clearly.
Most trips link several bases. Chiang Mai is the main hub, Pai suits a slow stop in a river valley, Chiang Rai sits near the northern border hills, and Sukhothai and Phitsanulok lie in the lower north. Mountain roads are slow, so a few nights in each base works better than moving every day. November to February has clear, cool air. March and April bring smoky haze, so plan around them. A loop through several provinces needs more than a long weekend.
Northern Thailand in five
- Travel between November and FebruaryThese are the cool, dry months with the clearest air. From about February to April, crop burning fills the northern valleys with haze, so check air-quality readings before you lock in dates.Best time to visit Thailand
- Pick two or three bases, not sixChiang Mai suits a first visit, Pai a slow valley stay, Chiang Rai the far north. Mountain roads are slower than the map suggests, so every extra base costs about half a day.Pai travel guide
- Add the lower north on the way up or downSukhothai and Phitsanulok sit between Bangkok and Chiang Mai, so they fit as a stop on the journey rather than a separate trip. Sukhothai's ruins need a full day by bicycle.Sukhothai travel guide
- Check helmet, license and cover before renting a scooterHill roads tempt visitors onto rented scooters. Thai law requires a helmet and a valid license for the vehicle, and many insurers exclude riders who do not hold one.Travel insurance guides
- Landing at Chiang Mai? File the arrival card firstWhether you fly in via Bangkok or direct, the free TDAC goes online within 3 days before arrival. Visa-free stays for most Western passports are 30 days from 15 September 2026, which a long northern loop can use up.Thailand entry rules

Read the guideNorthern Thailand FAQ
How many days do you need in Northern Thailand?
A week covers Chiang Mai and one extra base such as Pai or Chiang Rai. Ten days lets you add Sukhothai and Phitsanulok on the way back to Bangkok without rushing the mountain roads.
What is the best time to visit Northern Thailand?
November to February for cool, clear weather. March and April are hot and smoky from burning, and May to October is green and wet, with some landslide risk on mountain roads.
Is northern Thailand safe for scooters?
Scooters are the main way to get around Pai and the hills, and also where many visitors are injured. Wear a helmet, hold a valid license, avoid rain and night riding, and check your insurance wording first.
Should I fly or take the train to Chiang Mai?
Fly if time is short, since it takes about an hour. The overnight train suits those who want to save a hotel night and see the countryside, but it is slow and sleeper berths sell out in the cool months.
Can I do Chiang Mai, Pai and Chiang Rai in one trip?
Yes, in about 8–10 days, but every leg is a long mountain drive. Choose the order to avoid backtracking: Chiang Mai, then Pai by minivan, back to Chiang Mai, then north to Chiang Rai.
