(Trip completed on 12 March 2012)
My first trip on this road was northbound sans camera. I fell in love with this road so on my next Mae Sai run I decided to head over to Doi Mae Salong for lunch, and then run the length of the 3037 southbound from Tha Ton (20.062799,99.449594) to the junction of the 118 at Mae Suai (19.6731,99.55312). If I remember correctly it is a 75km stretch with plenty of twists and turns. It is certainly a nice break from the 118/Chiang Rai Highway Road.
Note: If you are heading north on the 118 look for the signs to Wawee. The turnoff is about 2km past the 109 junction to Fang.
Heading westward on the 1089 the turnoff sign is obscured so a keen eye is needed.

I pulled over for a little break
Nice twisty stuff
The 118 is down there somewhere...
