Chiang Mai to Mae Hong Son — Minivan via Pai and 1,864 Curves, the Gentler Southern Road via Mae Sariang, the Short Flight, and Planning the Mae Hong Son Loop
Two roads link Chiang Mai and Mae Hong Son: the northern route through Pai, shorter but full of curves, and the southern route through Mae Sariang, longer but smoother. Plus the short turboprop flight, how to survive a minivan if you get carsick, and how to plan the full loop.
Mae Hong Son is only 130 km from Chiang Mai in a straight line, but the roads form Thailand's most famous mountain loop. Whichever way you go, it is about half a day on winding roads, or a flight of under an hour over the top.
All options
| Option | Time | Notes |
|---|---|---|
| Minivan, northern road (Highway 1095 via Pai) | About 5–6 hours | Shorter, very curvy, lets you stop in Pai; the default |
| Bus, southern road (Highway 108 via Mae Sariang) | About 8–9 hours | Longer, wider and smoother; less motion sickness |
| Flight | About 35–40 minutes | Small aircraft, a few a day; reduced in some seasons, check the live schedule |
The northern road via Pai
Minivans leave Chiang Mai's Arcade terminal from early morning to mid-afternoon, climb Highway 1095 through Mae Malai and reach Pai in about 3 hours (this is the "762 curves" stretch the roadside signs boast about), then continue through Pang Mapha for another 2.5 hours to Mae Hong Son, about 1,864 curves in all. Vans are full and drivers are quick. If you get carsick, sit in the front row, take motion-sickness tablets before departure and do not eat a heavy meal. This road makes a night in Pai easy, since Pai–Mae Hong Son vans run all day.

The southern road via Mae Sariang
The older bus route runs down Highway 108 through Chom Thong, Hot and Mae Sariang, then north to Mae Hong Son, about 8–9 hours. Much longer, but the road is wider with fewer bends, and a full-size bus is more comfortable than a minivan. It suits anyone prone to motion sickness, or who wants to see the Salween river side and Khun Yuam. Most motorcyclists ride this road one way and the Pai road the other as the Mae Hong Son Loop, about 600 km.
Flying
Mae Hong Son airport is right beside the town. Flights from Chiang Mai use small turboprops and take about 35–40 minutes over mountains that cost the bus half a day. There are only a few a day, and airlines sometimes cut or suspend the route, so check the timetable well ahead and do not hang the whole trip on one flight. If time is short, flying out and riding back through Pai is a good formula.
Planning the full loop
A common itinerary: Chiang Mai → Pai (1–2 nights) → Mae Hong Son (2 nights, with Pang Oung and Ban Rak Thai) → Mae Sariang (1 night) → Chiang Mai. All by public transport it takes 5–6 days; every leg has scheduled minivans or buses, so you do not need to drive.
Seasons
The cool season, November to February, is best, with morning seas of mist and cold air. March to April is the burning season, with smoke haze, poor visibility and possible flight cancellations. The rainy season, June to October, is lush, but steep sections see occasional landslides; minivans keep running.
Common mistakes
- Taking the Pai minivan when you know you get carsick. Choose the southern road or fly.
- Booking the return flight tight against an onward flight from Chiang Mai. Small aircraft are delayed and cancelled more than usual; allow half a day.
- Not booking accommodation for New Year and Chinese New Year. Pai and Mae Hong Son fill up very fast.

Summary
If curves do not bother you and you want to stop in Pai, take the Highway 1095 minivan, about 5–6 hours. If you get carsick, take the bus via Mae Sariang or the 40-minute flight. With 5–6 days, do the whole loop by scheduled transport without driving.
