The US Gulf Coast refers to the coastline along the Southern United States, and includes all destinations along the Gulf of Mexico. This richly diverse and wonderfully scenic region stretches almost 1,900 miles (over 3,050 km) and encompasses the Gulf states of Florida, Alabama, Mississippi, Louisiana, and Texas. Characterizing the landscape is a collection of historic cities and a wealth of fabulous beach resorts, many set on the hundreds of unspoiled barrier islands that float parallel to the coastline. It's no wonder that exploring this astonishingly varied and compelling shoreline is one of America's most popular vacation options.
