One of Thailand's great drives — Chiang Mai → Pai → Tham Lod → Mae Hong Son → Khun Yuam → Mae Sariang, then back to Chiang Mai. This guide is honest about which way to drive, how many days you need, the key stops on every leg, whether to take a car or a motorbike, and the season that gives you the clearest mountain views.
The Mae Hong Son Loop is a ~600 km driving circuit out of Chiang Mai, famous for its 1,864 curves — a number that is signposted along the way and that riders love to photograph. The route takes you through some of the highest, most forested mountains in Thailand, past slow, still towns in the hills, and among Shan (Tai Yai), Karen and Yunnanese-Chinese cultures along the road. This is not a trip about ticking off sights quickly; here, the drive itself is the highlight.
The main circuit is Chiang Mai → Pai → Tham Lod / Soppong → Mae Hong Son → Khun Yuam → Mae Sariang → back to Chiang Mai (or the reverse), driving four to six hours a day on mountain roads over about 3–5 days depending on how much you stop. Because there are so many curves, the map distance is deceptive — 100 km on this road takes roughly twice as long as a normal straight route. This guide walks the loop leg by leg: where to stop, where to sleep and how to prepare.
Not keen to drive the whole loop but still want Mae Hong Son? See how to get to Mae Hong Son (there are small flights from Chiang Mai too) · want to time it right first? Read the best time to visit Mae Hong Son — the cool season is comfortable and clear, and you should avoid the March–April haze.
Both directions are a similar distance and both make one loop with no backtracking — the only difference is whether you take on Pai's heavy curves first or save them for later.
Head north from Chiang Mai to Pai first (Route 1095), continue to Mae Hong Son, then swing back south through Khun Yuam and Mae Sariang (Route 108). The advantage is that you take on the curviest, most fun stretch (Chiang Mai–Pai, 762 curves) on day one while you are fresh, and you reach each main town in daylight. The southern Mae Sariang–Hot stretch on the way back has fewer curves and is an easier long drive when you are tired at the end. This is what most people choose.
Go south to Mae Sariang first (Route 108), loop up to Mae Hong Son, and finish in Pai before returning to Chiang Mai. The advantage is that it pushes Pai's heavy curves to the end of the trip, which suits people who want to ease into the mountain roads, or anyone prone to carsickness who would rather tackle the toughest stretch once they are used to it. The trade-off is a longer first day before you reach the first town.
Out of Chiang Mai onto Route 1095 with its ~762 curves to Pai — a small valley town that makes the first overnight and a gentle warm-up for the mountain roads before the longer legs ahead.
The day starts in Chiang Mai — collect your rental car or motorbike, fill the tank before you leave the city, and head north to Pai on Route 1095 and its ~762 curves, about 3–4 hours including stops. Be honest about it: the curves are relentless and back-seat passengers get carsick easily — take a travel-sickness tablet beforehand and break the drive up. There are viewpoints and cafés to pull over and stretch. Leave early and you'll reach Pai around midday, check in, then explore in the afternoon.
Once in Pai, you can pick off the sights around town right away — Wat Phra That Mae Yen, a big white Buddha on a hill with a view over the whole Pai valley; Pai Canyon, the red-earth ridges that are the favourite sunset spot; and after dark the Pai Walking Street for street food and northern Thai–Shan dishes. Pai is a slow valley town and makes a good first night, letting you settle into the rhythm of the trip before the longer legs.

A favourite stretch — leave Pai, stop at Tham Lod Cave in Pang Mapha for a bamboo-raft ride through the cave, then drive on into Mae Hong Son town, the "City of Three Mists", before dark.
Leaving Pai toward Mae Hong Son, stop at Tham Lod Cave in Pang Mapha district (near Soppong) — a large limestone cave with a stream running right through it. The highlight is riding a bamboo raft with a local lantern-carrying guide who poles you in to see the stalactites and the big chambers. Stay until dusk and you'll see hundreds of thousands of swifts pour back to roost above the cave mouth. You hire the guide, lantern and raft at the site.
From Tham Lod it's another 1.5–2 hours into Mae Hong Son town, a valley town nicknamed the "City of Three Mists" for the mist that settles morning, evening and through the rainy season. It's small, quiet and strongly Shan (Tai Yai) in character. In the evening, stroll around Nong Jong Kham, the lake in the centre of town, where the Burmese-style temples Wat Chong Kham and Wat Chong Klang reflect beautifully on the water once they're lit. Find Shan food around the market.
Base yourself in Mae Hong Son for the next day's sights around town. See where to stay in the Top 10 Mae Hong Son hotels or the where to stay guide, and what to eat in the Mae Hong Son food guide.
The day without a long drive — use Mae Hong Son as a base for the standout sights nearby: the dawn mist at Pang Ung, the Yunnanese tea village of Ban Rak Thai, the Su Tong Pae bamboo bridge, and the town view from Wat Phra That Doi Kong Mu.
Get up before dawn and drive up to Pang Ung, a mountain reservoir ringed by pine trees that reflect on the still water, with light morning mist that has earned it the nickname "the Switzerland of Thailand" — a popular camping and sunrise spot. Then stop at Ban Rak Thai, a Yunnanese-Chinese village by a lake near the Myanmar border, with tea plantations, clay houses and tea houses to sit in alongside Yunnanese food — a community with a long heritage, worth visiting with respect.
In the afternoon, stop at the Su Tong Pae bamboo bridge, a long bamboo walkway across the rice paddies to a forest monastery — a calm walk out over the fields (best when the rice is green or golden). Finish the day at Wat Phra That Doi Kong Mu, a hilltop temple with a view over the whole of Mae Hong Son in its valley — the best spot for sunset and the town lights. With time to spare there's also Pha Sua Waterfall and Tham Pla (Fish Cave) to add.

The southern leg back on Route 108 — the WWII museum at Khun Yuam, the sunflower fields in the cool season, a night in Mae Sariang if you have time, then the loop back to Chiang Mai via Hot.
Head south from Mae Hong Son on Route 108 and stop at Khun Yuam, a small town with a WWII museum (the Thai-Japan Friendship Memorial Hall) that keeps the story and belongings of the Japanese troops who retreated through here during the war — a worthwhile piece of history many travellers never hear about. If you come in November, don't miss the Bua Tong (Mexican sunflower) fields at Doi Mae U Kho, which turn whole hillsides yellow — the cool-season highlight of this route.
Continue from Khun Yuam to Mae Sariang, a small, quiet, slow town with Shan temples, a morning market and a riverside setting on the Yuam River. It's a good place to break the journey before the long drive back to Chiang Mai. If you're doing the loop in 5 days, spend a night in Mae Sariang — it's far easier than driving the whole way back in one go. On a 3–4 day trip, many people stop here for a meal and a rest, then carry on to Chiang Mai the same day.
The final stretch runs from Mae Sariang back to Chiang Mai on Route 108 via Hot and Chom Thong, about 190 km in roughly 4–5 hours. This section has fewer curves than the Pai side and is an easier long drive (the reason many people save it for the way back). Reach Chiang Mai, return the vehicle, and the ~600 km loop is complete. From here you can carry on in Chiang Mai or fly home from Chiang Mai airport (CNX).
The question everyone asks — and the honest answer. Both are done all the time; it comes down to how confident a driver you are and who you're travelling with.
Popular with experienced riders because you get the mountain bends at their best, you're nimble and it's easy to stop for photos — but it really only suits genuinely confident riders. The curves are relentless for hundreds of kilometres, the descents are steep so your brakes must be good, and the gap between fuel stations on some stretches is long, so fill up every time you pass one. Wear a helmet at all times, and don't push it if you're not used to mountain roads.
Safer and more comfortable for families, larger groups, or anyone who doesn't want to be out in the sun and rain all day — air-con, room for luggage, and fine in the wet. The downside is that back-seat passengers get carsick easily on so many curves, so bring tablets and take frequent breaks. Choose a vehicle with good brakes and tyres and check it before you take it · or, if you'd rather not drive at all, hire a car with a driver or join a tour.
Drive slowly and never at night — allow time to reach your stop before dark, as the mountain roads have no lighting and the fog comes in fast. Check brakes and tyres before you set off, refuel at every station because some stretches are remote, and take frequent breaks, since the constant curves bring fatigue and motion sickness. In the rainy season (Jun–Oct) roads are slippery with landslides and rockfall — extra care. Four to six hours a day is plenty.

The big item outside the daily budget is the total vehicle rental for the trip plus fuel for the whole ~600 km loop · prices are approximate and vary by season — rooms are pricier and sell out fast in the cool season (Nov–Feb), so check before you go · to rent a car or motorbike or join a tour, search Mae Hong Son Loop tours and rentals on Klook.
This loop changes base most nights as you go — a night in Pai, one (or two) in Mae Hong Son, and a night in Mae Sariang/Khun Yuam on a 5-day trip. The main base is Mae Hong Son town; see the Top 10 Mae Hong Son hotels or the where to stay guide · Pang Ung and Ban Rak Thai also have on-site stays and camping if you want to catch the morning mist.
Nov–Feb is best — comfortable, clear skies, clear morning mist, and the Bua Tong sunflowers around November · avoid Mar–Apr, the burning season, when PM2.5 haze hides the views and sometimes affects flights — check an AQI app first · Jun–Oct is the rainy season, lush with full waterfalls and few crowds but slippery roads and landslides, so drive carefully. See the best time to visit guide.
Signal is weak or absent in places on the mountain roads, so set up a Thai SIM or eSIM for navigation and download offline maps as a backup — see the Thailand eSIM & SIM guide · pack a warm layer (the nights up in the hills are genuinely cold), travel-sickness tablets and a face mask if you come in the haze season. Start and finish in Chiang Mai — see the Chiang Mai guide.
