Just did the Chiangmai to Pai road today which I have not done for a couple of months. I could not believe how much it has deteriorated pot holes every where and fallen rocks across the road in many parts. I would advise extreme caution at present this is not a high speed road at present. Pai is though as good as ever with a vibe I like if you are an Ozzie a bit like Byron Bay was before being ruined by to much money. I always stay at the Brook View where they have great little Bungalows with a nice view of the Mountains for 500 Baht a night. The Brook View is located on the right hand side about 300 meters past the only set of Traffic lights heading towards Mahong Son.
