Mae Hong Son Loop Guide

The loop is two main roads. Route 1095 runs northwest from Chiang Mai over the mountains to Pai and on to Mae Hong Son, the twistiest half, and Route 108 runs south from Mae Hong Son through Khun Yuam and Mae Sariang, then east back to Chiang Mai, with the last stretch from Hot on straight highway. Expect 30 to 40 km/h on the mountain sections, so the distances take longer than they look.

You can ride it either way. Counterclockwise, via Pai first, is the classic order, starting with the famous road and ending on the easy highway. Clockwise, via Mae Sariang first, gets the dull highway out of the way on day one, puts Doi Inthanon early, and saves Pai, a good place to rest, for the end. Plenty of riders go each way, and the scenery is the same either way.

Mae Hong Son is the loop's halfway point and its quietest town, a small provincial capital of about 7,000 people in the Shan Hills by the Pai River, built around a lake. It was part of a Shan state until the 1890s, and it shows in the Burmese-style temples. Wat Chong Kham and Wat Chong Klang sit on the lake, and Wat Phra That Doi Kong Mu looks down from the hill above.

Spend two nights here. That gives you a morning ride north to Pang Ung and Ban Rak Thai, an afternoon at Su Tong Pae bridge and sunset at Doi Kong Mu. Guesthouses fill with Thai visitors from November to January, so book ahead for that season.

Rent in Chiang Mai, where there are dozens of shops. A 125cc semi-automatic, with gears but no clutch, is the sweet spot, with more control and engine braking on the long descents than an automatic, from about ฿200 a day for a week-long rental. If you'd rather not change gears, take a 150cc automatic at about ฿300 a day, because a small automatic struggles on the steepest climbs. Expect to leave your passport or a cash deposit of about ฿5,000, pay the extra for bike insurance, check the brakes and tires before you go, and ask for cords to strap your bag to the seat rather than riding with it on your back.

The roads are paved and mostly smooth, but they're steep, narrow and full of blind bends, and the main risks are fatigue, speed and rain. Ride in daylight, wait for morning mist to clear in the high valleys, keep to 120 to 150 km a day and wear a proper helmet. Legally you need an International Driving Permit with a motorcycle endorsement, and without one most travel insurance won't cover a crash. If you've never ridden a motorbike, the loop isn't the place to learn.

A car is the comfortable way to do the loop, and the better choice for families or in the rain. Rent one at Chiang Mai airport or in town, or hire a car with a driver for the whole trip. The roads are the same, and so is the advice to drive in daylight and take it slowly.

Without your own wheels, you can still see the province. Prem Pracha minivans run from Chiang Mai to Mae Hong Son several times a day in about six hours, about ฿340–380 on 12Go, and Ezy Airlines flies a 12-seat turboprop between Chiang Mai and Mae Hong Son in about 50 minutes, from about ฿3,000. A common plan is to bus to Pai, then on to Mae Hong Son, and fly back.

November to February is the season, cool, dry and clear, with January lows of about 14°C at Mae Hong Son and near freezing on the mountaintops at dawn, so pack a warm jacket. November and December add the sunflower hills at Doi Mae U Kho, and January is the busiest month, when rooms cost more.

March and April get hot, with the province averaging 38.7°C in April and holding Thailand's record of 44.6°C, and the burning season fills the valleys with smoke and haze. May to October is the rainy season, with afternoon storms, wet roads and landslides on the mountain sections, so ride in a car or pack serious rain gear.

Yes, if you enjoy the journey as much as the destinations. The loop is one of the great road trips in Southeast Asia, quiet mountain roads, misty valleys, Shan and hill-tribe villages and a province far fewer visitors reach than Chiang Mai or Pai. The towns themselves are small and low-key, so the reward is the road and the stops along it.

It's less worth it if you're a nervous rider, short on time or traveling in the rains. Five days of 100 to 200 km on mountain bends is tiring, and rushing it means skipping the detours that make it. With less time, ride Chiang Mai to Pai and back, or take the van to Pai and Mae Hong Son and fly home.
