Just north of the ever popular South Padre Island lies less known Padre Island, the longest stretch of undeveloped barrier island in the world. This national seashore protects 70 miles of coastline. Grab a kayak or canoe and explore the area by water or bike down the beach to get to know the shore. Camp in the park or reserve a room in Corpus Christi, where there's no shortage of boutiques, eateries, galleries, and more.
