I have just got back from a great 7 day trip starting from Bangkok and ending in Chiang Mai, but, by going the long way via the Mae Hong Son loop. Here is my trip report and some photos. Day 1 420km After much messing about we left Bangkok at about 9am, we took route 340 from the outer ring road and then onto the 346 all the way to Kamphaeng Saen. From there it was up along the 321 to U-Thong in Saphanburi. After reaching U-Thong we finally managed to get of the highways and onto the smaller 2 lane 333. It is then 90km to Ban Rai where the fun for the day begins. We had a quick lunch in Ban Rai and then rode the great little road to Lan Sak (3282). This was by far the best section of the day, traveling through green forest with lots of nice bends. After reaching Lan Sak the roads remain small but straight and fairly boring for most of the way. We took the 3456, 3504, 1072 and finally the 1117 ending at Kamphaeng Phet, where we checked into the Chakungrao Riverview hotel at about 5.30pm. Unfortunately we didn't take any photos on the first day as the roads were quite boring and we had a lot of ground to cover. However, we did take some photos of the old ruins in Khamphaeng Phet itself, which are really worth a visit if you are in the area.
