Swimming and snorkeling at Carlsmith beach park

The water temperature at Carlsmith beach park can be somewhat low because of cool fresh water that seeps in out of the ground in several areas. This has the effect of creating a few cooler spots throughout the lagoons. If the water is calm this is a good place for snorkeling, and turtles often visit this beach.

There is no sandy beach but a well kept lawn where you can lie down in the sun or shadow, and some picnic tables to sit down and have lunch / pupu’s.

A lifeguard is on duty on weekends and holidays between 9:30 and 4:45 p.m., and there are restrooms, a shower, drinking water and a picnic area.
