The Whirlin' Wavez was once a water park called Volente Beach on Lake Travis, situated near Austin, Texas, providing entertainment to people. It was surrounded by a solid fence and contained a lake as well as the usual water park amenities such as slides and car parks for customers.
The park was settled by a group of survivors, but was abandoned at some point.
The Whirlin' Wavez first appears in a flashback, where Alicia and Naomi arrive at the water park to search for supplies. Naomi finds a Land Rover but no keys. They spot an abandoned campsite at the top of a waterslide. They climb up a waterslide to reach the abandoned campsite. Alicia finds a machine gun with ammo. Naomi falls down a slide after Infected attack them. Alicia grabs onto the machine gun and falls down the slide. She kills an infected with the machine gun barrel and narrowly avoids landing in a pool of infected.
