At 173,000 square feet, Kalahari bills itself as America's largest indoor water park, keeping slides, rides, and toddler zones running regardless of weather. Day passes are sold alongside resort stays, making it the metro's big rainy-day fallback.
What's on site. OpenStreetMap maps parking at this location. No public toilets are mapped here — worth knowing before you commit to an afternoon.
When to go. Peak summer highs in Round Rock average 97°F. Mornings and late afternoons are far more comfortable than the middle of the day, and shade is worth planning around.
