Hawaii is one of the best locations in the world for scuba diving. The ocean temperature is warm year-round and the water is crystal clear, with a visibility of over 100 feet at some locations. Hawaii scuba diving tours are offered for both certified and non-certified divers. Non-certified dives are ideal for beginners and for those who would like to try this exciting water sport. Certified dives usually take place at more challenging locations with greater depths. Depending on which Hawaiian island you are on, you also have a choice between shore dives and boat dives.
