Just came back from a 4 day tour. I used my Yamaha Vmax and my friend rented a Honda Steed 600 at Jaguar on Moon Muang, good bike. Day 1: Chiang Mai to Phayao to Nan. Stayed in Devaraj Hotel. Day 2: Nan-Santisuk-Doi Phukha National Park-Pua-Chiang Kham. We stayed in Chiang Kham Garden, 450 baht for a good room. Day 3: Chiang Kham-Phu Chi Fa-Doi Pa Thang-Thoeng-Chiang Rai Day 4 : Back to Chiang Mai Nan province is by far the best biking I did, better than the Mar Hong Son Loop. Good roads, hardly any traffic. Apparently after arriving in Doi Pa Thang we should have turned right at the T, but we went left. Difficult descend on a Vmax, a lot of loose sand on the road, very slippery sometimes. On the Berndson/Berndson map this road is a secondary paved road, but it is not.
