Since this is a lagoon, the water is very calm and perfect for swimming, kayaking, and standup paddleboarding. You'll often see families with young children here, as the park is located at the back of a neighborhood. Since it is set off of the main road, it is quiet and typically uncrowded. Dogs are welcome here! There are restrooms and showers here too!

Free entry and a fantastic setting. A must see on Oahu. Unfortunately, stopping in the entrance area for a photo is forbidden, there were too many who stopped for Instagram.

Unfortunate, the area around the waterfall was very crowded and touristic. Nice waterfall though where you can also swim.
