The Mae Hong Son Loop Is Four Days on Two Wheels and Two on a Bad Idea
Eight hundred kilometres, the highest road in the country, a Karen village in the clouds and a very specific way to ruin it, which is trying in a weekend.
The road out of Pai climbs through a Karen village in the mountains where the fog comes up the valley at seven in the morning and sits in the trees like something alive, and there is a man selling coffee out of a bucket, and then the road drops into Mae Hong Son and the fog is gone and you are in the tropics again.
I did that four times in one week on a small scooter and it remains the best continuous piece of riding I have done anywhere.

What the loop actually is
It is a circuit through the mountains west and north of Chiang Mai, roughly eight hundred kilometres, and the route is Chiang Mai, Pai, Mae Hong Son, Mae Sariang, Tak, and back to Chiang Mai.
There are two mountain road options between the Pai and Mae Hong Son stages, and this is where most planning goes wrong. The route through Soppong and Pang Mapha is the one almost everybody means when they say the loop, and it is the one you want. The direct route on the 108 through Khun Yuam and the 1261 climb is harder, steeper, and considerably less interesting.
Day by day, honestly
Day one: Chiang Mai to Pai. Around a hundred and eighty kilometres, three to four hours, the 762 bends, and the road from our separate post on Pai applies. This is a long first day and the mistake is adding anything else to it.
Day two: Pai into the mountains. This is the best day on the loop and it is not close. Climb out of Pai, turn west, and the valley opens into the switchbacks up to Soppong. Stop at the hot springs and at the Karen village viewpoints, and give the whole day to it rather than riding to Mae Hong Son, which people try and regret.
Day three: down to Mae Hong Son. Short and beautiful, and Mae Hong Son town sits at over twelve hundred metres, which is why the whole place is cool, green and completely unlike the rest of the country. Go to the temple on the ridge above town in the late afternoon, and go to the war memorial, and eat the northern food.
Day four: Mae Hong Son south through Khun Yuam, which is the highest road in Thailand and where the Karen communities are. This is the wildest stretch of the loop and the part most likely to be closed by landslides in the wet season.
Day five: Mae Sariang, then south to Tak or the long way back. Mae Sariang is a small, quiet, beautiful town that almost nobody visits, and it is the sleeper of the loop. From there it is a decision about how you want to close the circuit.
And day six if you have it: the detour through Umphang, which is genuinely remote and one of the most beautiful places in the country, and which is the reason to allow six days instead of four.
How to do it
On a scooter, five to six days is the realistic minimum and four days is the aggressive version. You need a valid International Driving Permit with the motorcycle category, insurance that covers riding, and a tolerance for roads that are narrower, steeper and more broken than anything in the valley.
In a car with a driver, four days is comfortable and five is relaxed. The cost is roughly eight to twelve thousand baht a day for the car and driver for the full circuit, which is not cheap and is the correct answer for two or more people.
A scooter is a quarter of that and a completely different trip. It is exposed, it is slow, and it puts you in the weather, and that is the appeal rather than a compromise.
Do not attempt the loop on public transport and do not attempt it in two days. Both are attempted regularly and both go badly, because the interesting parts are the parts between the towns and the buses only reach the towns.
When to go
October to February is the window. Cool, clear, and the visibility on the high sections is genuinely spectacular. December and January at night, at the top of the Khun Yuam climb, will drop close to freezing.
March to May is hot, hazy and often smoky, particularly in the valleys.
June to September is the problem season. It is green, it is spectacular, and some of the mountain roads are subject to landslides and closures. Check conditions before you commit, carry rain gear, and do not ride a mountain pass in a storm.
And the road is called the Ghost Highway for a reason that is now mostly marketing, but the isolation on the northern sections is real and the stretches with no buildings for forty kilometres are not an exaggeration.
The practical things
Fuel. Available in the towns, sparse and priced badly in between. Fill up in Pai and again in Mae Hong Son, and do not trust a half tank on the Khun Yuam section.
Accommodation. Some places close entirely in the low season, which is a real thing and a real surprise if you arrive in November expecting a place to stay. Book ahead in December and January, which is also peak domestic travel.
Phones. Coverage is patchy in the mountains. Download maps before you leave, because navigation is where this loop will actually catch you out.
And cash. Bring more than you think. The towns have ATMs and the villages in between do not have anything at all.
The version I would actually recommend
Five days on a scooter, staying two nights in Pai, one in Soppong or Pang Mapha, two in Mae Hong Son, and a night in Mae Sariang, finishing from Tak. That gives you the good days at a human pace and puts the two most beautiful parts, the climb out of Pai and the descent to Mae Hong Son, on their own days rather than as drive-throughs.
And if you are not a confident rider, take the car. The loop is not going anywhere, the road will still be there, and a five-thousand-baht saving is not worth spending on a week of the trip being tense.
