Visit San Antonio
One of the most populous cities in the United States, San Antonio is an urban oasis with plenty of history packed into its streets. Named for Saint Anthony by its Spanish missionary founders, San Antonio was the first chartered civil settlement in what would become present day Texas. First part of the Spanish Empire and later the Mexican Republic, this Texan metropolis is home to some of the most widely known Texan historical sites.
If you’ve heard the phrase "Remember the Alamo," you may have been keen to create your own memories with a visit. The Alamo was built by Spanish missionaries in the early 1700s (flooding and other issues precipitated several moves until its current location was settled). However, the Alamo is best known for the 1836 Battle of the Alamo, during the Texas Revolution. The battle wiped out a small number of Texian soldiers who had managed to hold the fort for several months. When you visit, you can learn the long, storied history of the Alamo and the other four missions that comprise this UNESCO World Heritage Site.
Whether you're traveling to San Antonio for the history or for more modern endeavors, this town has a wealth of eateries, entertainment, and culture to offer. The famous River Walk gives San Antonio its River City nickname. This path alongside the San Antonio River meanders through downtown, offering trickling water and beautiful views, and shady spots to sit and admire them. You can even catch shows at the Arneson River Theater; the stage sits on the north side of the river and the audience sits on grassy steps on the south side. This theater features folkloric dance troupes, plays, concerts, and more.
If museums and art are what you're after, San Antonio's collections range from the traditional to the uniquely Texan. Explore the San Antonio Museum of Art one day and The Buckhorn Saloon & Museum the next. Discover the first museum of modern art in Texas, the McNay Art Museum, as well as the Texas Rangers Museum and the Texas Transportation Museum. No matter your taste in art or preferred museum experience, San Antonio has something for you. And remember to take advantage of San Antonio's warm climate. Check out the San Antonio Botanical Garden as well as Brackenridge Park and the Japanese Tea Gardens for outdoor adventures.
Visit San Antonio to take in some of the Lone Star State’s most famous historical sites, fascinating museums, beautiful outdoor spaces, and delicious cuisine. Southwest® is proud to serve San Antonio International Airport. And when you book with Southwest, know that you can book with confidence.
