Fiesta Texas - A Six Flags Theme Park - Visitors at Six Flags Fiesta Texas will be thrilled and refreshed as they "tube the funnel" on Tornado, the park's new award-winning extreme tubing experience. Visible from the parking area, Tornado looks much like a giant, 60-foot tall household funnel that's been turned on its side. Tornado is now open at Armadillo Beach Waterpark, Six Flags Fiesta Texas' two-level waterpark that is free with park admission.  Plus more!!!
