You can do this route on a motorbike or in a car. A regular sedan is fine — the main road is paved the whole way (Highway 1095 for the Chiang Mai–Pai–Mae Hong Son section, and Highway 108 for Mae Sariang–Chiang Mai), but the curves are constant and genuinely steep. Anyone in the passenger seat who gets carsick easily should bring medication. We suggest driving counter-clockwise — Pai first — because the roughest stretch (the 762 curves up to Pai) falls on day one while you're still fresh, and you save Highway 108, which is wider with fewer curves, for the last day heading home.
Before you set off
Always fill the tank in Chiang Mai and again in Pai — gas stations are far apart on the Pai–Mae Hong Son–Mae Sariang stretch. Check your tyre pressure and brakes carefully. If you rent a motorbike in Pai town, photograph its condition before you take it every time.
Day 1 — Chiang Mai up to Pai via Huai Nam Dang
Day one has the most curves of the whole trip. It's only 135 km, but the actual driving takes about 3–4 hours because you're crawling through the bends. Leave a bit early and you can catch Huai Nam Dang before the fog burns off.
Day 1
Chiang Mai → Huai Nam Dang → Pai (135 km)
07:30
Leave Chiang Mai on Chotana Road (Hwy 107) through Mae Rim–Mae Malai, then turn onto Highway 1095Grab khao soi or sticky rice with grilled pork to line your stomach before you go — there are few shops along the first part of the road.
09:30
Stop at the Huai Nam Dang viewpoint (Huai Nam Dang National Park), the route's best-known sea-of-fog spotPark entry is around 40 THB for Thais. The fog is best in the cool season (Nov–Feb) in the early morning; arrive late and it will have thinned out.
11:30
Carry on through the 762-curve section into Pai, with toilet breaks at the roadside pull-offs along the wayThis is the most nausea-inducing stretch. Drive slowly; passengers should look far into the distance, which helps.
13:00
Reach Pai, check in, and have lunch around the Pai Walking Street — for example Witching Well, an Italian spot near the walking street, or a northern-Thai restaurant in townPai has everything from cheap hostels to resorts with rice-field or riverside views along the Pai River. Book ahead in the cool season.
15:30
Look around Pai — the historic Tha Pai Bridge (a steel bridge from World War II) and Wat Nam HuBoth are just outside town in the same direction, so you can knock them out together.
18:00
Walk the Pai Walking Street, grab street food, and sit in a café with live musicThe walking street is lively every evening with plenty of snacks, starting at just a few tens of baht.
If you get carsick easily
The Chiang Mai–Pai stretch is one curve straight into the next, almost without pause. If you're prone to motion sickness, take medication 30 minutes before leaving, sit up front, look far down the road, and avoid your phone while moving.

Day two is around 110 km but still all mountain road with plenty of curves. Catch the Pai sea of fog in the morning first, then drift down toward Mae Hong Son. You can stop at Tham Lod cave if you start early.
Day 2
Pai → Tham Lod → Mae Hong Son (110 km)
06:00
Head up to the Yun Lai viewpoint to watch the sea of fog over Pai at sunriseEntry is about 20 THB, and there's warm Chinese tea for sale up top. It's bitterly cold on winter mornings — bring a warm layer.
08:30
Come back into Pai for breakfast or coffee, then pack up and hit the roadYou can stop at Coffee in Love or one of the mountain-view cafés near the edge of town.
10:00
Stop at Tham Lod cave (Pang Mapha district), a large limestone cave with stalactites and stalagmites — you hire a lantern-carrying guide and ride a bamboo raft across the stream insideGuide plus raft runs about 100–200 THB per group and takes around 1–1.5 hours. It's a fair detour off the main road.
13:00
Have lunch around Pang Mapha/Sop Pong, then drive on into Mae Hong Son townFor local food, try khao soi, Tai Yai (Shan) noodles, or northern-style fermented soybean dishes.
15:30
Arrive in Mae Hong Son, check in, and stop by Nong Jong Kham lake to see Wat Chong Kham and Wat Chong Klang, Shan-style temples in the centre of townThe two temples sit inside one wall beside the lake in the middle of town — a lovely spot for a stroll and photos.
17:30
Drive up to Wat Phra That Doi Kong Mu for the evening view of Mae Hong Son nestled in its mountain basinThis is the best sunset and town-view spot, and you can drive all the way to the top.
19:00
Walk the Mae Hong Son night market beside Nong Jong Kham and eat local Tai Yai foodThe atmosphere is far quieter than Pai — good for anyone who likes small, slow-paced towns.
Day 3 — Pang Ung and Ban Rak Thai, a full nature day
Today you don't have to drive far. Use Mae Hong Son as your base and loop out to Mok Champae sub-district north of town, taking in Pang Ung and Ban Rak Thai, which sit on the same road. This is the nature highlight of the trip.
Day 3
Mae Hong Son → Pang Ung → Ban Rak Thai (round trip ~100 km)
06:00
Set out before dawn to Pang Ung (Pang Tong Royal Project 2) and take a bamboo raft to watch the mist drift over the lake amid the pinesThe fog is best very early, before 8 a.m. Rafting runs about 300–400 THB per raft. It's most beautiful — and coldest — in the cool season.
09:00
Have breakfast around Pang Ung, then drive on up to Ban Rak Thai, a Yunnanese Chinese village right on the Myanmar borderThis stretch of road is narrow and steep — drive carefully, as it's tight when cars pass each other.
10:30
Explore Ban Rak Thai, sip oolong tea, and eat stewed pork leg with mantou buns and Yunnanese food beside the reservoir, with its clay-and-tile housesSeveral tea houses and Yunnanese restaurants are open around the village — you can taste the tea before buying any to take home.
13:30
Drive back into Mae Hong Son town for a lunch breakIf you have time left, stop at the Su Tong Pae bamboo bridge across the rice fields south of town.
16:00
Add an extra stop — the Su Tong Pae bridge in the evening light, or relax in town to rest up for the last day's driveIf you like a slow pace, just hang around town — tomorrow is the longest driving day.
Mexican sunflower fields
If you come from mid-November to early December, stop at the Bua Tong (Mexican sunflower) fields on Doi Mae U Kho (Khun Yuam district) on the way back. The yellow blooms cover entire hillsides — it's the peak season for Mae Hong Son all year.
Day 4 — Loop back to Chiang Mai via Mae Sariang
The last day is the longest drive, about 270 km, heading south on Highway 108 through Khun Yuam–Mae Sariang and then curving back up to Chiang Mai. Highway 108 is wider with far fewer curves than the Pai side, so it's a lot easier going — a good way to close the trip when your body is tired from the first three days.
Day 4
Mae Hong Son → Mae Sariang → Chiang Mai (~270 km)
08:00
Leave Mae Hong Son heading south on Highway 108 through Khun Yuam (stop at the Doi Mae U Kho sunflower fields if you're there in season)Fill the tank before you leave — gas stations are spaced out on this stretch.
11:30
Reach Mae Sariang, break for lunch, and wander the town's small marketMae Sariang is a quiet halfway-point town with khao soi and noodle shops to choose from.
13:00
Carry on along Highway 108 through Hot–Chom Thong, heading for Chiang MaiIf you have the time and energy left, turn off up Doi Inthanon (Chom Thong district) to bag Thailand's highest peak — but you'll reach Chiang Mai after dark.
16:30
Arrive in Chiang Mai, return the rental (if you rented), and close the loopIf you complete the full loop, you can collect a 'conquered the Mae Hong Son loop' certificate at the Mae Hong Son Chamber of Commerce — a small fee, with local coffee included.
Three days or five — which is better?
The 4-day, 3-night plan above is the sweet spot for most people — you actually get to see things without driving yourself into the ground. But if you're short on time or have extra, here's how to adjust.
Short on time3 days, 2 nights
Cut the nature day at Mae Hong Son — one night in Pai, one in Mae Hong Son, then loop back. Good if you're short on time, but it'll feel like more driving than sightseeing.
Recommended4 days, 3 nights
The plan we recommend. You get Pai, Mae Hong Son, Pang Ung, Ban Rak Thai, and Highway 108 on the way home, all at a comfortable pace.
No rush5 days, 4 nights
Add another night in Pai or Mae Hong Son — a full day on Pai's cafés, or an unhurried overnight stay at Ban Rak Thai.
What to prepare before this loop
- Best season — November to February: cool weather, thick fog, sunflowers in bloom. Avoid March–April, when wildfire smoke and haze hang heavily over all of northern Thailand.
- Vehicle — a sedan handles it fine, paved the whole way, but if you ride a motorbike you should have mountain-road experience and wear a full-face helmet.
- Accommodation — book ahead in the cool season and over long weekends; Pai and Ban Rak Thai fill up fast.
- Cash — carry cash. Small shops, viewpoints, and raft fees are mostly cash-only, and ATMs are hard to find outside the towns.
- Warm clothes — mornings and evenings up in the mountains get genuinely cold, especially Pang Ung and Yun Lai in the cool season.
