A great ride from Chiang Mai to Pai, it is possible to off road a loop back to Chiang Mai but the map does not show it. Rent a bike in Chiang Mai and go for it, beutifull scenary.
Nort Thailand is biker's heaven.
I have been driving in north Thailand twice, -07 and again this winter, total round 2500km.
Norht Thailand is all this: Thousands of curves, very good road surface (asphalt), nearly no traffic, beautiful scenery,good food, nice people and cheap. What else do you ...
A real curve-fest! Pai is about 3 hours from Chiang Mai. Just about right for a day trip. I read somewhere that there are 800 curves between Chiang Mai and Pai. The road surface isn't the best but, it's not terrible either. I really enjoyed it. Pai is a backpacker stop with lots of restaurants.
