Splashtown San Antonio, San Antonio

More than 45 water rides and attractions swerve and spray across the 20 landscaped acres of Splashtown San Antonio. A seven-story triple tube ride sends guests speeding through a series of corkscrew turns and sudden drops, the park's wave pool sends huge swells of water toward bodysurfers, and a pair of enclosed water slides generate part of their thrill from the pitch darkness. Some of these thrills may be a little too thrilling for young ones, but have no fear, Kids Kove has expanded adding Splash Island and kids pool.

The adrenaline-boosting attractions may be attention-grabbing, but it's also easy to just relax in the sun. The park also boasts a tree-lined lazy river, and basketball and sand volleyball encourage fun competitions on dry land. Splashtown San Antonio even rents out shady cabanas for groups with as many as 12 people, giving visitors a private retreat where they can dry off, catch their breath, and finally try to find chlorine on the periodic table of elements.
