Looking to cool off? Don't miss Austin's Barton Springs Pool – a natural spring-fed watering hole that's three acres in size and a constant 68-degrees. If you prefer marked lanes, head to Deep Eddy. It's the oldest swimming pool in Texas with a shallow area perfect for the kids. During summer months, check out Splash Party Movie Nights – where family-friendly movies like Indiana Jones and the Last Crusade and Disney's Tangled are screened.
