The New Braunfels-based Schlitterbahn, long Texas' most famous waterpark, keeps islanders cool every summer, too, at this 26-acre Galveston park that offers 30 attractions. Chief among them are the thrills of a "transportainment river system" that connects Whitewater, Kristal and Torrent rivers, allowing guests to float throughout the entire park without ever leaving the water. General admission $50.99; children (ages 3-11) and seniors $38.99. Check the website for specials and discounts.
