The Big Thing in Chiang Mai: the Sunday Night Market.
Every Sunday evening, a seemingly endless row of stalls stretches from Tha Phae Gate all the way to Wat Phra Sing — probably about a kilometer — plus several side streets. You’ll find lots of typical evening market goods, but also some interesting stalls selling unique jewelry, clothing, and more. Every few meters there’s a massage booth. There’s live music on a small scale, and at the temple grounds, large food courts where you can grab a bite, so no need to eat beforehand. Definitely a must-visit if you’re in Chiang Mai on a Sunday.
There’s also a Saturday Night Market, which we say here is "same same but different" — a lighter version of the Sunday market. You don’t need to visit both. The Saturday Night Market starts at one of the southern gates — the eastern one of the two.
