The Louisville Zoo has consistently tried to maintain a high standard of living for its animals as it has evolved over the last several decades. Like many smaller to medium sized zoos, it tries to keep a mix of the expected animals as well as a few species that perhaps you haven't seen anywhere else before. It is easy to get around with wide sidewalks, though it does have hilly areas that will give you some exercise getting from some parts of the zoo to others (this is not a bad thing--just something to note if you tire easily). I have visited the zoo at least half a dozen times, and always enjoyed it. I look forward to seeing the polar bear exhibit the next time I go--it was under construction at our last visit.
