The Honolulu Zoo is a smaller, quiet zoo located at the end of the Waikiki strip. The outside is surrounded by a lush green plants and vines. It looks secluded area but once you get it, it even feels like you're in a different place. The zoo has a decent number of species to look at and you can get pretty close to the animals.
Admission is under $10 so it is worth it to plan to stay inside and have a picnic, etc.
