Underwater Oahu offers daily 2-tank scuba tours as well as monthly special event dives and night dives on Oahu. A short boat ride away and just below the surface is another world. A world of vivid turquoise waters, abundant with beautiful corals, teeming with an amazing variety of colorful reef fish. Explore wartime wrecks, lava tubes, caverns and coral reefs where dolphins, spotted eagle rays, turtles and tropical fish are your dive companions. Although we primarily dive the west side of Oahu, we also do boat diving on other parts of Oahu. So call today to check availability and book your seat!
