After reading entries from this site, I thought this would be easy for beginner divers. Entry was easy from left of lagoon in the boat channel. Very murky water until you swim out past the rock wall of the lagoon. Lots of reef fish and some sandy bottoms. Exiting seems a bit scary for a beginner. Do not exit around to Ala Moana Beach. The waves crash on the surfaced reef that is protecting the beach. Waves seemed at least 5ft high. Better options were to go through one of the openings that lead back to lagoon or back around to the beach entry in the boat channel side.
