The zoo is very nice, and well done, but it is very large and crowded. We were not able to see it all in a day because we wore out before we finished. They were almost finished building a rope walk type thing in the trees when we were there last July. It actually opened later that week, so we didn't get to try it out. We purchased a 2 day ticket but went to the Safari Park the second day. We actually liked the Safari Park just as well. It was extremely hot there because it is more inland, but they have trams to take you around the place. There were so few people there, we couldn't believe it! The Safari Park is actually a breeding facility for the zoo. Very interesting, but may be too hot for the little ones. They also offer jeep type tours, Segway tours, etc. for an extra fee.
