San Antonio is a popular tourist destination. The jewel of the city is the River Walk, which meanders through the downtown area. Lined with numerous shops, bars, and restaurants, as well as the Arneson River Theater, this attraction is transformed into an impressive festival of lights during the Christmas and New Year holiday period, and is suffused with the local sounds of folklorico and flamenco music during the summer, particularly during celebrations such as the Fiesta Noche del Rio. Also based along the River Walk is the newly restored Aztec On The River, the only surviving exotic-themed movie palace in Texas.

The Alamo, located nearby, is Texas' top tourist attraction, while the River Walk is the second most visited attraction. SeaWorld, located 16 miles (26 km) west of downtown, is the number 3 attraction. Also, there is the very popular Six Flags Fiesta Texas. Morgan's Wonderland is a theme park for special needs children.

The downtown area also features Cathedral of San Fernando, The Majestic Theatre, HemisFair Park (home of the Tower of the Americas and the Institute of Texan Cultures), La Villita, El Mercado, the Spanish Governor's Palace, and the historic Menger Hotel. On the northern side of the Alamo complex, beside the Emily Morgan Hotel, is the San Antonio Cavalry Museum, which features cavalry artifacts and exhibits and is frequented by local re-enactors.
