Molokai Fish & Dive is Molokai's official scuba diving operator, running boat dives on the island's roughly 30-mile-long south shore reef, one of the largest and least-disturbed reef systems in Hawaii with nearly 40 dive sites. Trips run aboard three US Coast Guard-certified boats (the Nai'a, Coral Queen and Ama Lua) and commonly encounter green sea turtles, spotted eagle rays, manta rays, Hawaiian monk seals and dolphins. The operator also runs Molokai's Fish & Dive sporting-goods store in Kaunakakai.
