Thanks David,yes sorted now.I have explored the north in Dec and Jan for the last three years.I base myself in Chiang Mai,plenty of longstay apartments.Lots of highlights, the Mae Hong Son Loop is a must,a spectacular 600km trip,winding over steep forested mountains and through tightly hemmed farming valleys.I usually stay in Mae Hong Son overnight and return to Chiang Mai the next day,but for a change it can be nice to take it easy and explore around Mae Hong Son.Exploring around Mae Sariang is good as well,the 105 from Mae Sariang to Mae Sot along the border with Burma is interesting. Stunning views deserted roads long fast sections, smooth asphalt then just around the corner it can reduce to a steep winding pot hole nightmare, all good fun though.About 60kms north of Mae Sot you pass a very large refugee camp which is home to around 40,00 karen refugees from Burma.North through Chiang Rai to the golden triangle is always worth while, the loop on the 1089 to the mountain chinese Kmt village of Doi Mae Salong is recommended also the ride from Mae Sai along the border with the Mekong river via Chiang Saen,Chiang Khong to Wiang Kaen,Thoen and back again is always enjoyable so is a trip to Nan.The ride to Nan should include the Doi Phukha Loop up a spectacular 2,136m mountain its a roller coaster ride on steep winding deserted roads it must be one of the best loops in northern thailand.
Recommended day trips from Chiang Mai include the 100km Samoeng Loop,and the fast half day ride to Phrao is fun.I would also highly recommend the book Guide To the Golden Triangle by David Unkovich,and of course the The Golden Triangle maps of Northern Thailand are a must.
The above roads are just a sample of whats on offer in the north,it must be one of the best kept biking secrets in the world,anyone out there who is thinking about travelling there just go for it,after all motorcycling is the best fun you can have with your clothes on.
Take care
Tony
