A new route for us. Locals informed us the road was a bit bumpy for the first 10km and then was great. 60km later and wishing I was on a D Tracker and not a ZX10 the road changed. There is a lot of work going on and give it 6 more months and this will be one awesome route. As it was after the 60km marker out of Mae Sariang the road became an absolute joy. Perhaps it might be better to try it from Mae Sot and turn around and enjoy it all over again when you hit the road works. Passes by the huge Burmese refugee camp, quite a sight.
