I've then to the Honolulu zoo. If you have taken your children to a big-city zoo don't bother with the Honolulu zoo - it would just be a disappointment. It's a decent zoo but nothing spectacular. The petting zoo area is a disappointment, and is awfully hot and dry when you could be at the aquarium or on Waikiki Beach. if your children don't have an opportunity to go to the zoo very often than by all means take them -- there's reptiles, giraffes, elephants, a small bear, a nice playground, plenty of birds and more.
