This Wat has a beautiful hall, as well as the Stupa with the cremation remains of various monks, or kings? I don't remember the entire history, but this Wat has a very interesting one, and is one of the oldest ones in Chiangmai. I recommend going and walking around, absorbing the beautiful location, and at the same time being respectful of all of the monks and novices that live and study there and at the next-door Buddhist University. Also, go to the Monk Chat! It's a great opportunity to learn more about Buddhism and Monk's lifestyle from the monks there, and for them to practice speaking English and learn about Westerners as well.
