I really liked the zoo! It was more beautiful than I expected. Mostly very nice enclosures, great collection.
I visited on a sunday, so no entrance fee (expect for the herpetario and insectario), but that also meant it was very, very crowded at some parts of the zoo.
I was able to add several new (sub)species to my mammal list (volcano rabbit, red brocket deer, Mexican black howler, Mexican prairie dog, Mexican wolf).
Unfortunately, about half of the bird section was closed (Montezuma aviary and aviaries with the birds of prey). However, I had some luck, as the first aviary after the road block was that of the Californian condors and one was sitting high in the aviary. So I got a distant view of it and could add the Californian condor to my zoo list of birds of prey!
