The Mae Hong Son Loop is the reason a lot of people come to northern Thailand on two wheels. Roughly 600 km of mountain road wind northwest from Chiang Mai through Pai, Mae Hong Son, Khun Yuam, and Mae Sariang and back again, past waterfalls, hot springs, caves, hill-tribe villages, and viewpoint after viewpoint, linked by thousands of curves. Ridden unhurried over several days, it is one of the great road trips in Asia. This guide gives you the route, a day-by-day plan, where to stop and stay, fuel and distances, which way to ride, and how to do it safely.
For the wider picture and the shorter rides, see our motorbike trips hub.
The route in brief
The loop is a circle you can ride in either direction:
- The north leg (Route 1095): Chiang Mai to Pai (762 curves) to Mae Hong Son, via the Pai canyon, hot springs, and the Tham Lod cave country. The most famous and most twisting section.
- The south leg (Route 108): Mae Hong Son through Khun Yuam and Mae Sariang back to Chiang Mai, generally quieter and with longer flowing sections, often paired with a Doi Inthanon detour near the end.
Total distance is roughly 600 km, more with detours. Most riders go anticlockwise (north to Pai first), tackling the hardest, busiest section while fresh and saving the calmer south leg for tired days.
A day-by-day plan (5 days)
This is the comfortable version. Compress to 3 days if you must, or stretch to 7 to savour it.
Day 1: Chiang Mai to Pai (about 130 km, 762 curves)
A half-day of relentless, beautiful curves on Route 1095. Stop at viewpoints and roadside coffee. Arrive in Pai by mid-afternoon, leaving time for the canyon at sunset, the hot springs, and the night market. Stay 1 to 2 nights; Pai is worth lingering in.
Day 2: Pai to Mae Hong Son (about 110 km)
More mountain riding through Soppong and the Tham Lod cave area (a worthwhile detour, with Cave Lodge nearby for an alternative overnight). Continue to Mae Hong Son, the quiet provincial capital with its lake, morning market, and the hilltop temple of Wat Phra That Doi Kong Mu at sunset.
Day 3: Mae Hong Son to Mae Sariang (about 160 km)
The longest and most remote leg, through Khun Yuam (a good lunch and fuel stop, with its WWII museum). The road is quieter and flows more than the Pai section, but services are sparse, so keep the tank topped up. Mae Sariang is a relaxed riverside town for the night.
Day 4: Mae Sariang toward Doi Inthanon (about 150 km)
Ride east and north, with the option to climb Doi Inthanon, the highest road in Thailand, for waterfalls and the misty summit. Stay near the mountain or in Chom Thong.
Day 5: Doi Inthanon area back to Chiang Mai (about 100 km)
An easier final leg back into the city, ideally finishing by early afternoon. Return the bike, and feel the curves in your shoulders for a day or two.
Where to stay
| Town | Known for | Nights |
|---|---|---|
| Pai | Canyon, hot springs, night market | 1 to 2 |
| Soppong / Tham Lod | Cave, Cave Lodge | Optional |
| Mae Hong Son | Lake, temples, market | 1 |
| Khun Yuam | Quiet midpoint, WWII museum | Optional |
| Mae Sariang | Riverside, relaxed | 1 |
Guesthouses and small hotels cover all budgets. Book ahead in the cool-season high season (November to February) and around holidays; arrive-and-find works the rest of the year.
Fuel and distances
- Main petrol stations are in Pai, Mae Hong Son, and Mae Sariang.
- Bottled roadside fuel is sold from village shops and stands where stations are scarce; useful, if pricier per litre.
- The remote stretch between Mae Hong Son and Mae Sariang is where people run low; fill up before it.
- Plan around roughly 150 km of safe range, less on a small scooter tank, and top up at every chance in the mountains.
What to pack
- A proper helmet (rent a good one or bring your own), and at the least a light jacket, long trousers, and closed shoes. Gloves and eye protection strongly recommended.
- A warm layer for cold mornings and the Doi Inthanon summit.
- A rain shell, especially in the wet season.
- Phone mount and offline maps; signal drops in the mountains.
- A small toolkit, a tyre-repair option, and the rental shop's contact number.
- Cash; ATMs are scarce between the main towns.
- Sunscreen, water, basic first-aid, and any personal medication.
Safety on the loop
- Ride in daylight only. The curves, unlit roads, and wandering animals make night riding far riskier.
- Keep an unhurried pace. Blind bends, gravel, and oncoming trucks crossing the centre line reward caution, not speed.
- Rest often. Fatigue on twisty roads is a genuine hazard; stop for coffee and views.
- Never ride after drinking, and avoid riding in heavy rain.
- Carry the right licence and confirm insurance before you go; see our honest-reality guide.
- Check the bike (brakes, tyres, chain, lights) before leaving and have any doubts sorted by the rental shop.
Guided or independent?
Confident riders do the loop independently and love the freedom. Newer riders, nervous riders, or those short on time can join a guided motorbike tour, which handles the bike, the route, the bookings, and a support vehicle for luggage or breakdowns. It costs more but lowers the stress and the risk. Either way, the loop is the highlight of riding in northern Thailand.
The bottom line
The Mae Hong Son Loop earns its reputation. Give it 4 to 7 days, ride a capable bike at a sober daytime pace, pack for cold mornings and remote stretches, and let the curves and the mountain towns do the rest.
