I can't believe there is only one dive site for the entire island! This is a great place for scuba/snorkel anything you want! The shore diving is great in the Opunohu Bay. You can go at the public beach on the North east shore, there is a little spot where there is a white house with a big wall and coconut trees hanging over the water, we called it White House Wall. This has a fringe reef which drops off and has an underwater wall covered with all sorts of fish and cool corals. On the other side of Opunohu Bay there is a Coconut grove which is closer to the barrier reef which is great spot to snorkel or dive. There are many other places to dive including the motus on the Northwest side of the island and in Cook's Bay. This is an amazing place! Go for a dive on the outside of the reef for a even more amazing dive. I can't wait to go back!
