North-west Thailand: Chiang Mai - Mae Hong Son area

I’ve just finished a section of my website on a week-long holiday I had in north-west Thailand:

I’ve already posted the link on the ‘motorcycle touring’ thread but I think it might be worth posting it here as a separate thread as well because the section has photos and info that might be of interest to anyone who is thinking of going there, not just for motorcycle touring.
I think doing this makes it easier to search for, and may also attract a few people who don’t read the motorcycle touring thread. Sorry if this is considered crossposting, mods - delete it if you want.
