Just came back from a 6 day MHS loop trip (September, supposed to be real bad weather wise) and lucky as we were, we had 6 days of sunshine. Between Pai and Sappong some road work was being done due to the heavy floodings and land slides some weeks ago, but apart from that the roads were a dream. Even the side roads up, down, left, right, north, south, east, west were all of a superb quality, we did the trip on a rented Superfour (Honda) and apart from the poor machine having troubles climbing the Doi Inthanon ;-) only few short distances were dirt and could easily be done with a road bike. Enjoy!!!
