Cool Gulf waters, sand dunes covered in rustling sea oats, emerald marshlands, wildlife refuges, and cosmopolitan glamour define the Gulf Coast region, better known as the Texas Riviera. Major cities and hide-away resorts dot the more than 600-mile (969 km) stretch of beaches that feature water sports, plus unique historic and cultural attractions. The city of Houston hosts performing arts and concerts, sports events, and family amusement parks as well as a major international airport. The resort islands and coastal cities, such as South Padre Island, Corpus Christi, Galveston, and Port Aransas offer relaxing beach vacations.
