Oahu diving is awesome thanks to the lava that has poured into the ocean for centuries creating lava tubes, arches, caves and caverns, canyons, crevices and pinnacles. There are also sunken vessels around Oahu. The clear warm water and abundance of colorful fish and sea creatures make Oahu the perfect place to dive.

If you are a certified diver, you can rent equipment at numerous dive shops and then go out on your own, or you can arrange for a chartered excursion. Chartered excursions are run by local Oahu diving professionals who know where Oahu’s best dive spots are located.

If you are not certified or are just a beginner, local dive shops offer introductory dive courses that take about four to six hours. You will learn the rules of the deep and how to get comfortable with the equipment. The beginner dive course is usually a two tank dive, no deeper than 30 feet and only four students per instructor. This is relatively inexpensive.
Aqua Zone offers a free scuba clinic for people 10 years of age and up. Oahu diving is a thrilling experience.
