The San Antonio River Walk is a city park and special-case pedestrian street in San Antonio, Texas, one level down from the automobile street. The River Walk winds and loops under bridges as two parallel sidewalks lined with restaurants and shops, connecting the major tourist draws from the Shops at Rivercenter, to the Arneson River Theatre, to Marriage Island, to La Villita, to HemisFair Park, to the Tower Life Building, to the San Antonio Museum of Art, to the Pearl and the city's five Spanish colonial missions, which have been named a World Heritage Site, which includes the Alamo. During the annual springtime Fiesta San Antonio, the River Parade features flowery floats that float down the river.
