San Antonio has a nearly overwhelming amount of attractions. Six Flags? SeaWorld? San Antonio has them both. And San Antonio offers far more than big franchise names. The city itself has an attraction air. The San Antonio River Walk is rightfully famous - you have to walk it during one of the many fiestas, or during Christmas, when the river is lit up bright with floating candles.
There are the historic attractions as well, such as the Alamo, kept in both Texan and American memory by movie and song and carefully preserved today. The Alamo is just one of San Antonio's missions, however. The San Antonio Missions National Historic Park shelters four missions from the expanse of the city, all in astoundingly good condition and all beautiful.
