This is not the tequila-infused spring-break hot spot of the same name. The bottom 70 miles of North Padre Island are empty, save for some fishermen and sea turtles. From Corpus Christi, take South Padre Island Drive south, cross the bridge, and stop at the visitor center to register. Keep going on to South Beach, a 55-mile stretch of sand that's technically a state highway (four-wheel drive is essential). Pitch a tent dune-front, look across the Mansfield Channel, and thank God there are miles between you and Girls Gone Wild XXXV.
