Those seeking a little Texas frontier history are sure to find it here -- San Antonio proudly touts sites like the Alamo, San Antonio Missions National Historic Park and the Spanish Governor's Palace. The museums, such as the San Antonio Museum of Art, are also not to be missed. This city also makes for a great family vacation -- with educational and adrenaline-pumping fun. SeaWorld and Six Flags Fiesta Texas will thrill both you and the little ones. And no city tour would be complete without a stroll down the River Walk, a three-mile-long path along the San Antonio River, which hits many attractions.
