World's Largest Swimming Lesson

An Aquatics Center Community Event

This event requires purchase of a day pass by the General Public. Purchase a pass at the customer service desk in the Fitness & Wellness Center upon arrival.

The World's Largest Swimming Lesson™ (WLSL) is a global drowning prevention event launched by the World Waterpark Association in 2010. The program is supported by leading aquatics and safety organizations around the world and takes place at all types of aquatic facilities from huge waterparks to public pools and swim schools. WLSL serves as a platform to help communities build awareness about the fundamental importance of teaching children to swim.

Swimming is a life-saving skill for children and a vital tool to prevent drowning, the number one cause of death for US children ages 1–4, and second leading cause for ages 5–14.

Research from the American Academy of Pediatrics shows risk of drowning can be reduced by 88% if children participate in formal swimming lessons between the ages of 1–4. Yet, a survey conducted by the American Red Cross in 2020 found that more than half of Americans (56%) either can't swim or don't have the necessary basic swimming skills. TEAM WLSL™ is on a mission to make everyone aware that swim lessons are vital.

Come join us for our 15th anniversary World's Largest Swimming Lesson™ event! TEAM WLSL™ has sent the message Swimming Lesson Save Lives™ to billions. Register and help share this important message with as many kids and adults as possible this summer.
