Ten miles east of Waikiki via Kalanianaole Highway, this bay is a protected nature park (entrance fee required), which means loads of fish.
Snorkeling here is the closest to swimming inside an aquarium as you will find in Hawaii.
The superlative scenery is a bonus.
Several shallow lagoons between the beach and reef are perfect for beginners.
But get there early. Parking is limited, and it fills up quickly.
Open daily from 6 a.m., closed Tuesdays, Christmas Eve and Christmas Day, New Year's Eve and New Year's Day
