Toronto Zoo is definitely worth your time no matter what age you are. I came here during my vacation to Toronto. I would be lying if I said I am not here to see the Pandas for the first time of my life and definitely NO REGRETS, it was a wonderful experience with or without the pandas. We got our tickets through Toronto CityPASS for $64+Taxes CAD (5 Attractions) the Zoo individually would be around $28 CAD and the weather was great that day. The Zoo was crowded yet still clean compare to New York. It is separated into different themes:
Eurasia Wilds, Tundra Trek, Americas, Canadian Domain, African Savanna, Indo-Malaya.(African Savanna is HUGE)
(My experience of seeing pandas for the first time)
Da Mao and Er Shun were both separated. At first I saw Da Mao through photos posted on Yelp. I told my sister we must look for Da Mao and it turned out he was a sleepy potato. He slept on the side of his cheeks and looked up for 2 seconds and went directly back to sleep on his face. Er Shun was more active and moved around to her second play house and munched on her bamboos (my sister even recorded her pooping - haha; Don't ask why). Their play house was very creative and seen very suitable for them. Then the Red panda(Looks a bit like a raccoon) are also in the Zoo. The little fellow was also munching on his bamboos, they even have signs directing you to look up because the red pandas have a hard time dealing with hot and humid weather. Then when I look up, I saw his buddy on the tree. Both types of Pandas are really really cute.
Of course there is a lot of other interesting animals but i took approximately 7 hours to walk through the zoo. So you get the point you have to experience it with your eyes! And warning: if you want to go through the whole zoo it is going to be really tiring. Overall it was wonderful and educational experience. Most of the animal lived in an imitating of natural environment and they also seen healthy compare to a lot of other zoos. Toronto Zoo is definitely a well design environment for their animals.
