Molokini Molokini is an offshore volcanic crater south of Ma‘alaea Bay , Maui , Hawaii and part of Maui County . It is a popular destination for scuba diving and snorkeling with many tourist boats coming each day from the south coast of Maui . While it is a popular tourist destination due to its offshore , exotic location , many watersport enthusiast guides note that overcrowding has made the experience less attractive . The islet is a Hawaii State Seabird Sanctuary . Because this very popular dive spot was attracting large numbers of boats , each potentially damaging the surrounding reef by dropping anchor , the Hawaii State Division of Boating and Recreation established mooring buoys and `` Day Use Mooring Rules '' for Molokini . The United States Census Bureau defines Molokini as Block 9000 , Block Group 9 , Census Tract 303.02 of Maui County , Hawaii . The uninhabited island ( as of the 2000 census ) has a land area of 0.093 km² ( 0.036 sq mi or 23.02 acres ) .
