Favourite Two/Three Day Breaks In Chiang Mai Province

Perhaps not more than two or three hours away from town.

Just wondering of any nice resorts or places where the sights and sounds of nature can be enjoyed. I already know of chiang dao, pai, so wondering if enough posters can put up their favourite breaks to escape from urban life for a couple of days and to recharge up one's spiritual energies. Perhaps we might get a thread with a fair few choices; i'm sure getting away for two or three nights is a popular thing with chiang mai residents.

If it's within a two hours or so drive, perhaps we could include lamphun or other surrounding provinces.
