Love the zoo. We had a season pass and went whenever the weather was good (not too hot) The best part of the zoo, in my opinion, is the squirrel monkey exhibit. You get to walk thru with all the little cuties hanging around. We managed to go last when they had their little babies on their backs, too cute. We also like when they have the stingray exhibit, check for schedule, my daugther spends tons of time touching them. It does cost extra for this exhibit but if you have kids it is worth it. We did try a 2 person bike rental to view the zoo. My suggestion is to have 2 adults peddling. My child was not able to help much and my legs hurt and on some of the hills I had to push it. If you are lucky enough, usually earlier in the day, you will find the handlers taking care of and feeding the animals. They are very happy to answer questions and tell interesting stories about their charges. We also like to go early because all the animals are usually up and about. The little critters (chipmunks?) are still out searching for food and are fun too watch as well.
