Zoos do not normally appeal to me, but the Portland Zoo is one of the nicer ones I have seen. Many of the habitats blend well into the northwest ecosystem and the animals don't feel so out of place. This zoo is also very large; it would be easy to not make it through the whole thing in one day. The zoo also offers special discount days (although will be overrun with kids and field trips).
