Why Chiang Mai deserves your time
Chiang Mai became the capital of the Lanna Kingdom in 1296, when King Mengrai chose a site between the Ping River and Doi Suthep mountain and enclosed it with the square moat and walls that still outline the Old City today. Lanna kept its own kings for centuries before Siam absorbed it, and the temples, script and cuisine that developed under them still set the city apart from Bangkok. Doi Suthep on the mountain above town and the White Temple at Chiang Rai are the northern entries in most accounts of what to see in Thailand, and khao soi comes from the same Lanna kitchen.
Neighbourhoods to know
Old City temples fill the moated square at the centre, still the base for most first visits. Nimmanhaemin, west toward Chiang Mai University, holds the city's cafe and gallery scene, while the streets east of the moat around Warorot Market and the Night Bazaar keep the trading city's older commercial pulse. Mae Rim and the mountains north and west, reached by road, hold Doi Suthep, elephant sanctuaries and waterfalls.
When to go and for how long
November to February brings the coolest, driest weather and the clearest mountain views, while the burning season from February to April fills the valley with smoke haze from crop fires and pushes temperatures toward 40°C by April. Three to four days cover the Old City, Doi Suthep and a day trip into the surrounding hills at a comfortable pace.
Getting around
The Old City is compact enough to walk between temples, and red songthaew pickup trucks alongside ride-hailing apps such as Grab cover the rest of the city and the roads up to Doi Suthep and Nimmanhaemin easily enough that few visitors bother renting a car.
