Waikiki Diving Center

One hundred feet beneath the surface of Maunalua Bay, the Corsair⎯a World War II airplane—rests on a sandy floor. Its massive shell and magnetism for schools of soldier fish lures deep-sea explorers to the site every year. As divers propel themselves alongside the plane's wing and fuselage, they get an up-close look at the wreck's current residents, which range from colorful goatfish to reclusive moray eels.

With more than 30 years of experience, the scuba instructors at Waikiki Diving Center lead daily dives to submerged sites such as the Cosair wreck. Earning a five-star Instructor Development Center designation from the Professional Association of Diving Instructors, the center's team coordinates parties of 12–14 people and takes them out on one of two customized dive boats—The Submariner or Snoopy V—for adventures ranging from snuggling sea turtles to earning PADI open-water certifications. To enhance visitors' experiences, Waikiki Diving Center's crew arranges complimentary shuttle service to and from Waikiki hotels.
