The best time to visit would be on a sunny day. This will typically involve larger crowds, but, that's part of the fun. On our visit, the crowds were present due to a big concert in the zoo that evening. Parking at the zoo can be hard to find, but, they have a satellite parking lot that they run free shuttles to and from. We took advantage of that and had a great time seeing all the wonderful animals. The caracals, hippos, bears, and elephants were particularly active and entertaining on our visit.
