The outdoor expansion at Kalahari Resorts and Conventions in Round Rock has a kid’s waterslide area, adult swim-up bar and 900-foot adventure river.

ROUND ROCK, Texas – One of “America’s largest indoor waterparks” is opening Thursday in Round Rock, just north of Austin. Going to a waterpark in November might not sound like a great idea, although who really knows with Texas weather, but an indoor waterpark makes year-round visits possible no matter what it looks like outside. The 350-acre resort complex will include 223,000 square feet of waterpark, which would put it at No. 2 in size behind DreamWorks Water Park in New Jersey, a 370,260-square-foot waterpark. The African-themed resort and water park will be located on U.S. 79 near Old Settlers Park.
