The Chiang Mai zoo is amazing. It is a very large mountain based zoo with a modern set up and can easily rival some other great zoos I have been to (e.g. San Diego or Animal World). They have Giant Panda's which you can see really up close (and hey: they really move as well). Lot's of animals you can feed - which we did with the Giraffes and the Hippos. It was almost 35 degrees, but the trees kept us in the shade.
