You are probably familiar with Wat Doi Suthep, maybe also Wat Doi Kham, but how about Wat Ban Pong? It is another temple, or at least a pagoda on a hill top. And with a great challenging staircase for the people that wants the excercise. Chiang Mais white pagoda on the hill really stands out in the landscape, and the temple is really one of these local treasures. Still under construction it will take some time before it becomes a major tourist attraction.
In San Patong outside Chiang Mai you can see one of the most impressive private collections of dolls in the world.
