Ko Olina Lagoons
Waianae Leeward Oahu
These four man made lagoons located on the leeward side of the island are wonderful beaches. They offer great protected swimming and the snorkeling is exceptional once you swim out a little towards the rocks. Be careful for the currents once you get close to the openings. If you want a parking spot make sure to arrive before 10am or just come later in the afternoon for any of them. If you can make sure you catch a sunset from one of these lagoons, they are extremely gorgeous.
