This is a massive zoo. Located about 1.5 hr bus ride from the city center. The #5 bus takes you to the zoo. The zoo was built along the mountain range, which provides natural environmental elements for the animals: valleys, hills, mesas, etc. They highlight that they have won numerous awards and try to provide a sanctuary for the animals.
This is a zoo with some animal shows: parrots riding bicycles and doing math, and tigers/lions jumping through hoops. Although the enclosures are well built and large for the animals, there's still an issue with litter. Signs are everywhere, but you can see litter inside the enclosures and people actively throwing food wrappers and bottles at the animals to "see" what they'll do (esp. the monkey exhibit). There's no one policing the visitors. The animals seem to be happy, but upon a closer look, you can see that, for example, the horses' hooves don't get care, so they grow long causing their legs to get all bent.
If you're an animal activist or whatever, you may not want to visit.
