If you’re a seasoned motorcyclist searching for your next epic ride, Northern Thailand is a paradise of twisty tarmac, mist-cloaked mountains, and warm-hearted locals. From legendary routes like the Mae Hong Son Loop to hidden backroads like R 1026 toward Sirikit Lake, this region offers the best riding in Southeast Asia, with smooth pavement, jaw-dropping scenery, and culture at every stop.

At Bike Tour Asia, we’ve spent more than a decade riding, mapping, and guiding every bend, café, and mountain pass. These are our top 10 motorcycle riding roads in Northern Thailand, now expanded to include our favorite hidden gems from our original list — routes like R 1026, R 4001, and R 1256 —, chosen for their flow, views, and sense of adventure. Whether you’re joining one of our Thailand Motorcycle Tours or planning a self-guided adventure, use this guide to map your next unforgettable journey.

1) R 1095 – The Mae Hong Son Loop (1,864 Curves)

No list is complete without the Mae Hong Son Loop, Northern Thailand’s holy grail of motorcycling. Stretching from Chiang Mai to Pai and Mae Hong Son, this 600 km circuit winds through lush jungle, rice terraces, and misty mountains.

Why it’s legendary

• 1,864 bends — officially counted — making it the twistiest route in the country.
• Perfect asphalt maintained by local tourism authorities.
• Endless mountain vistas, tiny villages, and coffee stops every few kilometers.
  
  

Insider tip
Start early from Chiang Mai, overnight in Pai, and continue to Mae Hong Son. Watch for cold morning mist in the cool season and fuel up before Soppong.

Bonus route from our original list:

• R 108 – Khun Yuam to Mae Hong Son – A wider, faster section of the same loop, perfect for warming up with longer curves before the tighter Mae Hong Son switchbacks.

2) R 1148 – Nan’s Perfect Rider Highway

This 70 km masterpiece from Phu Langka to Wang Pha is often called  Thailand’s best-surfaced road, R 1148 between Nan and Phayao offers pure riding joy, long, flowing corners through unspoiled forest.

Highlights

• Glass-smooth pavement with elevation changes is perfect for big bikes.
• Virtually no traffic.
• Great coffee stops at Phu Langka Viewpoint and the “1148 Riders Stop.”

“At sunrise, we dropped into a sea of clouds below the ridge, the road completely to ourselves.”
— Daniel, Bike Tour Asia Founder

Safety note: Watch for fog before 8 am and occasional farm trucks.

Supporting route (from original list):

• R 1026 – Toward Sirikit Lake – Connects with the Nan region; remote and wilder, with a pontoon ferry crossing the Nan River. It’s perfect for riders seeking more adventure off the main highway.

A hidden gem connecting Nan and Bo Kluea, this road hugs the Laos border and passes through pristine mountains and salt-mining villages.

Why ride it

4) R 1155 – Chiang Khong to Phu Chi Fa

This route climbs from the Mekong River to the misty cliffs of Phu Chi Fa, a must-see sunrise viewpoint overlooking Laos.

Why we love it

• Sweeping switchbacks with expansive Mekong valley views.
• Authentic villages and local coffee farms.
• Connects seamlessly to our Ride of a Lifetime Tour.
  

5) R 120 – Lampang to Phayao

A silky-smooth, lesser-known gem with just the right rhythm of bends.

Route summary

• ~100 km of perfect asphalt connecting Lampang and Phayao.
• Excellent mix of tight and open corners for all rider levels.
• Light traffic — ideal for warming up on Day 1 of a tour.

6) R 1093 – Sky Road to Phu Chi Fa

“Few places in Thailand make you feel like you’re flying — R 1093 is one of them.”

- Por,  Bike Tour Asia Administrative Manager

For those who crave dramatic scenery, R 1093 delivers mountain-edge riding with unbroken views of Laos.

Highlights

Route facts
