As with most water parks, there are rules that must be followed or they will ask you to leave. Respect the rights of others, no profane language, no running, no smoking, no radios, no pets, and no one under the influence of alcohol or drugs will be permitted in the park.

Appropriate Swim Attire. No cut-offs, no thong swim suits, no undergarments or gang attire. Swim diapers must be worn for those who are not potty-trained.

Kids under 9 must be supervised by someone at least 15 years old.

No outside food or drinks except water in clear plastic containers. There is a snack bar on site.

The facility and slides are used at your own risk.
