There are bigger and better zoos, but this one, though showing signs of neglect due to budget constraints, is a lush garden and has some great programs. To get a glimpse of the endangered nene, the Hawaii state bird, check out the zoo's Kipuka Nene Sanctuary. Though many animals prefer to remain invisible, particularly the elusive big cats, the monkeys appear to enjoy being seen and are a hoot to watch. It's best to get to the zoo right when it opens, because the animals are livelier in the cool of the morning.
The Wildest Show in Town is a 10-week summer concert series ($3 participation fee). Or just head for the petting zoo, where kids can make friends with a llama or stand in the middle of a koi pond. There's an exceptionally good gift shop. On weekends, the Art on the Zoo Fence, on Monsarrat Avenue on the Diamond Head side outside the zoo, has affordable artwork by contemporary artists. Metered parking is available all along the makai (ocean) side of the park and in the lot next to the zoo—but it can fill up early. TheBus makes stops here along the way to and from Ala Moana Center and Sea Life Park (routes 8 and 22).
