Coming from NYC, we have several zoos to visit. I was interested how the zoos of Thailand measure up. I previously visit the Dusit Zoo in Bangkok and enjoyed the different.animals (This zoo is now closed for renovation).
Chiang Mai zoo had some pretty cool exhibits, one being able to feed the giraffes, another feeding a leopard raw meat. They also have a panda exhibit that is extra but no worth it. The poor thing is sitting sadly (if you are even able to see him).
The zoo is very hilly so be prepared to hike the hills or ride the train. I am just fine to walk and enjoyed the exercise.
Overall I enjoyed the zoo, not a must see, but a decent place to visit.
