We visited this zoo while in Portland and found it to be lacking. The animal enclosures that have been updated are really nice like the elephant area. The house that all of the primates are in is not quite so. We found ourselves feeling a bit sorry for them. There are not really all that many animals at this zoo compared to some others around the US. If you visit many it might be better to visit the Japanese Gardens, is the general opinion.
