Mae Sai
แม่สาย
Give Mae Sai one night as a border-market stop on the Chiang Rai loop, or skip it: the Myanmar crossing is closed to foreigners, so there is no day trip.
Mae Sai is Thailand's northernmost town, 61 km north of Chiang Rai on Highway 1, and it exists mostly as a border market facing Tachileik in Myanmar. The land crossing has been closed to foreigners, so the old visa-run and day-trip reason for coming is gone. What is left is a one-street market town, a hilltop temple with a giant scorpion, and the Tham Luang cave 30 km south. Come for one night on the way to or from the Golden Triangle, or skip it and use Chiang Rai as the base.

Etiquette, safety and scams
Etiquette
- Greeting: A wai (palms together, slight bow) to return a greeting; a smile and nod for shop staff; avoid: Waiing children or service staff first — it confuses; hugging strangers
- Head and feet: Keep feet on the floor, sit with legs folded to the side in temples; avoid: Touching heads (even children's), pointing feet, stepping over people or food
- Temples: Covered shoulders and knees, shoes off, sit lower than monks; avoid: Women touching monks or handing them things directly; climbing Buddha images
- Monarchy: Stand for the royal anthem in cinemas and at 08:00 and 18:00 in public places; avoid: Any joke or comment about the royal family; stepping on a banknote
- Keeping calm: Stay polite and smiling when things go wrong ('jai yen' — cool heart); avoid: Raising your voice; public anger loses the argument
- Names: Khun plus first name ('Khun Somchai'); nicknames are normal; avoid: Using the family name alone
- Home visit: Shoes off; bring fruit or sweets; step over the threshold, not on it; avoid: Sitting with feet towards the family shrine
- Beckoning and pointing: Palm down, fingers waved towards you; point with the whole hand or chin; avoid: Pointing at people with a finger or with your foot
Scams and watch-outs
- The Mae Sai–Tachileik land border is closed to foreigners as of Dec 2025; do not plan a Myanmar day trip. Crossing may be possible on an organised tour only — ask at the border before committing.
- Smoke season runs roughly Feb–Apr; air quality in the far north can be poor enough to change plans.
- The town empties by 22:00; there is no late-night scene and few taxis.
- Border-market gems and curios are sold on trust: buy only from shops that give a receipt, and expect import duty at home.
Mae Sai is a small, calm border town and violent crime against visitors is rare. The real issues are the closed Myanmar crossing, smoke-season air, unlit pavements after dark and gem or curio sellers with no posted prices: agree the price before you buy.
