About the Event 

The Naples Island Swim is an open water swimming competition featuring 3 races of differing lengths. The event is held in the Alamitos Bay in Long Beach, CA. The events span from a 500 yard swim for ages 10 and under to a one mile swim for 11 and over and a three mile Naples Island circumnavigation for 13 and over.

Alamitos Bay is no stranger to open water swimming competition. In 2010 Marine Stadium played host to both the USA Swimming Open Water National Championships and the Pan Pacific Championships open water competition. In 2023 it will host the inaugural MPSF Open Water Swimming Championship. It is the training ground for many local athletes. The Naples Island Swim is an annual opportunity for the City of Long Beach, known as the Aquatic Capital of America, to showcase its leading position as a destination for aquatic activities.

The 2023 event has concluded.

About Aquatic Capital of America

Aquatic Capital of America is a 501(c)(3) nonprofit, public benefit corporation established in 2008 to promote the myriad of aquatic activities offered in Long Beach; to recognize, honor and support the City of Long Beach and its aquatic athletes and organizations; improve and increase local aquatic facilities and promote water safety and education. ACOA also supports community and regional efforts to raise awareness about water quality and the reduction of pollution on our beaches and in our local waterways.

Because Long Beach has so much water - ocean, bay, lagoon, Marine Stadium, plus a river on each side of the city - and so many water-based activities, every Long Beach child should know how to swim. A significant portion of the net proceeds from this event will be used to further the objective.
