The Mae Hong Son Loop: 4,088 Curves, 8 Days, Zero Regrets

There's a sign at the edge of Chiang Mai pointing toward Pai. It says: 762 curves.

That's not a warning. That's an invitation.

I rode the Mae Hong Son Loop in September 2025 — 8 days, about 600km through the mountains of Northern Thailand. The route goes Chiang Mai → Pai → Mae Hong Son → Khun Yuam → Mae Sariang → back to Chiang Mai. Here's what I actually found.

In the town center of Mae Hong Son there's a sign that lays out exactly what you're doing. Chiang Mai to Mae Hong Son via Mae Sariang: 1,864 curves. The full Mae Hong Son Loop: 4,088.

The Road

The 762-curve road to Pai is famous enough that trucks dread it and motorcyclists love it. Well-maintained, banked right, and the views open up about halfway through when you're above the valley floor. But Pai is the warm-up. The section from Pai toward Mae Hong Son is where it gets good — you gain elevation almost immediately and spend the morning in cloud forest, mist sitting in the valleys below you.

Mae Hong Son province sits on the Myanmar border. The town has maybe 8,000 people, ringed by mountains, more Buddhist temples per capita than anywhere else in Thailand. The morning mist doesn't burn off until 10am. The khao soi is different here than Chiang Mai — richer, more coconut, more Shan.

The temples in Mae Hong Son are extraordinary and almost no one is there. Walk around in the morning before the mist clears. Most riders stay one night and move on. That's the wrong call.

The Towns

Pai is a famous backpacker town, which sounds like a red flag but isn't. It's popular because it works. The infrastructure is perfect for slowing down — hot springs 8km south, a canyon that looks like it belongs in Utah, waterfalls, a night market, coffee shops run by people who moved here and never left. Give it two nights. Everyone who gave it one night wishes they'd given it two.

Khun Yuam is the most remote night on the loop. It's worth it for the WWII Japanese Army Museum alone — small, low-budget, genuine. Japanese soldiers were stationed here in 1944–45 and the museum is run by the town.

Mae Sariang gets rushed through on the way back to Chiang Mai. Don't. It's a market town with Burmese-influenced food, an old quarter worth walking, and views across the Salween River to Myanmar.

The Guesthouses

Everything is guesthouses. Budget ฿400–800/night ($12–23). Basic and fine — you're mostly sleeping and moving. Pai River Corner in Pai is the standout: riverside bungalows, hammocks, motorbike parking.

The guesthouses have a personality of their own. This elephant was on my bed in Mae Hong Son. I don't know who made it or how long that took them.

The Fuel (human edition)

M-150. 12 baht a bottle, tastes like cough syrup mixed with ambition, available at every convenience store on the loop. Jason drank 15 of them over 8 days, plus one Red Bull on the climb out of Mae Sariang.

We also ate 12 bowls of khao soi between us. I'm not sorry about any of them. The one in Mae Hong Son itself is the one to seek out — richer and more Shan-influenced than the Chiang Mai version you've probably already had.

Practical Notes

When to go: November through February. Dry season, cool mountain mornings, clear visibility. I went in September (monsoon) and it rained every afternoon — the roads are still fine, but you're wet.

How long: 6 days minimum. 8 is better. 10 means you can actually slow down.

The bike: A 125cc automatic will get you around fine. A 150cc semi-auto gives you more engine braking control on the mountain descents. The roads don't require a big adventure bike — a semi-auto is what locals ride.

Fuel: Fill up whenever you see a petrol station past Mae Hong Son. They get sparse.

Road condition: Good on the main loop. Check recent rider reports before you go — there's an active community and someone will have ridden it in the past week.
