The Toronto Zoo is a great place to see lots of animals in the world, especially the giant panda. The zoo is huge, and requires a lot of walking if you're planning to see everything. However, the zoo has a Zoomobile, which you can use as a bus, getting off at certain stops where the attractions are.
The variety of the animals in the Toronto Zoo is enormous. They have everything from Alpacas to Zebras. The only zoo that comes close to matching the variety of the Toronto Zoo is the National Zoo in Washington D.C.
