Watercolor fun in the tot pool and hot tub, inner tube polo and parent and child game time! Lifeguard Training starting soon as well. Check it all out here.

Cleaner, Greener

We recently installed an advanced water treatment system on the Don Nakata pool. The Hanovia UV system utilizes powerful light technology designed to destroy potential bacteria, viruses, micro-organisms and chloramines. Within a week of operation, the pool chloramines were reduced in half and today the unpleasant odors caused by chloramines have nearly been eliminated. Our service to the swimming community has never been better. Hope to see you soon. Read all about it here.
