About this swimming hole
Carlsmith Beach Park is a chain of spring-fed lagoons with sandy bottoms and clear, calm water, protected by a lava reef that keeps the surf out. Sea turtles regularly visit, and a rope swing draws local teens. With restrooms, showers, and a lifeguard, it is Hilo's most family-friendly swim.
