National Waterpark Day | July 28
(Last Updated On: November 8, 2022)


On July 28th, laughter and fun are just a couple of the requirements on National Waterpark Day! We also recommend bathing suits!


Waterparks around the world provide thrilling, water-plunging rides for those who seek the white-knuckle hydro-power of slides. For those who prefer to relax and unwind, waterparks answer the call. Vacationers find lazy rivers, wave pools, and spas in tropical scenes quite satisfying.

With so many options to choose from, waterparks can be more than just a portion of a vacation. They can be the destination. In the United States, nearly every state has a waterpark. Impressively, the Wisconsin Dells is the Waterpark Capital of the World. However, the largest indoor park in America is currently at Kalahari Resorts and Conventions in the Pocono Mountains, Pennsylvania.

From the youngest family member to grandma and grandpa, there’s a splashable, relaxable experience for all. On National Waterpark Day, enjoy all the memory-making waterparks have to offer!


Don’t wait! The water is perfect at a waterpark near you. Grab your bathing suit and make a splash. While you’re celebrating, be sure to invite others to join you. It’s also a great day to share your favorite waterparks. With so many to explore, be sure to get in on all the splashing fun! Don’t forget to use #NationalWaterparkDay to share your experiences on social media.

Kalahari Resorts and ConventionsNATIONAL WATERPARK DAY HISTORY

Kalahari Resorts and Conventions founded National Waterpark Day on July 28, 2017, to celebrate the unique attractions waterparks offer especially during the height of summer. After opening their first waterpark in July 2000 in the Wisconsin Dells, they expanded to other areas of the country. Visit the Pocono Mountains in Pennsylvania or Sandusky, Ohio for more waterpark fun. In March 2017, the resort opened phase two of its waterpark in the Pocono Mountains. The expansion also dethroned the Sandusky location as America’s Largest Indoor Waterpark. The resort was awarded #1 World’s Coolest Indoor Waterpark by Conde Nast Traveler in 2014.

The Registrar at National Day Calendar® declared the observance to be celebrated on July 28th, annually.
