The manmade Ko Olina Lagoons are a great way for you to kick back and relax. The four lagoons — Hanu, Naia, Kolola, and Ulua — are setup with nice amenities like showers, restrooms, picnic areas and beach shops. Lifeguards are typically on duty, for an extra set of eyes to look out for any kids playing in the water.
The lagoons are located on southwestern Oahu and much less crowded than the popular Waikiki Beach. The Ko Olina Lagoons are definitely worth checking out any time your visiting Hawaii!
