Do you have the desire to swim with sharks? One Ocean Diving presents an incredibly distinct shark diving experience, led by marine scientists trained under the acclaimed shark specialists Ocean Ramsey & Juan Oliphant. We take pride in being the pioneer company in Hawaii and the U.S. to offer cage-free shark diving, boasting an unblemished safety history.

Our guests receive training on how to respond when a shark comes close, a knowledge that could prove useful in their lifetimes. In addition, we offer education about shark sensory systems and science, and involve participants in data gathering exercises. All dives are overviewed by the marine scientists leading the adventure who are in the water with the guests at all times (they are the first to enter and the last to exit the water). Conservation information and ways to contribute and participate are also relayed. One Ocean Diving’s program is a branch of the One Ocean entity that carries out further conservation and research activities worldwide.
