The historically significant Alamo is San Antonio’s most popular attraction. During Texas’ war for independence from Mexico, a group of Texans occupied the Alamo for 13 days. Although they lost the battle, the Alamo has become a symbol of resistance against oppression. Other must-see sites include the bustling Riverwalk, the San Antonio Zoo, the San Antonio Missions, the Natural Bridge Caverns, Six Flags Fiesta Texas, and the list goes on!
