Well, you are on vacation right? Sometimes you need to just take a day and chill out. Have a few beers and simply take in the natural beauty around you that is Chiang Dao. Talk to a few locals, and take a walk around. Drive to a temple, or try to get lost. I think you will find it hard. Have a nice cup of coffee to warm you up on a cool mountain morning. Go get yourself a foot massage, or do my personal favorite thing to do on such a day .... just sit and drink beer with good company. Either way, you really can't go wrong in this small town that still has managed to retain much of the charm that makes it unique.
