Just a tip to avoid R1129 Chang saen - Chiang Khong on the Chiang Saen side of the mountain "Kiu Khan." The road is being widened & is full of potholes & in the wet covered in slurry - potholes connected by slurry. If it rains you cant see how deep the potholes are - which ones to hit or miss. My travel time last Sunday was 1 hr 40 minutes for the 54 kms = not much fun at all. Once you are on the Chiang Khong Mekong side of Kiu Khan the road is ok, but the CHiang Saen side sure as hell sucks big time. Sorry no photos I was too cranky & busy concentrating.
