Dive into summer with the World’s Largest Swimming Lesson on Thursday, June 25, at 10 a.m. This globally synchronized event aims to spread the vital message of water safety and drowning prevention.

The lesson will take place at Wild Rivers Waterpark, 10000 Great Park Blvd., Irvine, CA, where participants of all ages are invited to join thousands around the world in this record-setting initiative.

Registration is $40 per person, which includes:

  • Admission to the 10 a.m. swimming lesson
  • Full-day access to Wild Rivers Waterpark
  • Water Safety Fashion Swim Goggles and Wet Dry Bags (for the first 150 participants)
  • Foam Party with DJGP at 11 a.m.
  • A $20 donation directly benefiting the Jasper Ray Foundation’s work in drowning prevention

Drowning is a leading cause of death for children ages 1 to 4 and the second leading cause for children ages 5 to 14, yet it is entirely preventable. Teaching children how to swim and practice water safety is a critical life skill that can save lives, especially during the summer months.

Join the mission to save lives through water safety education.
