Austin is the capital of the U.S. state of Texas and the seat of Travis County.
As Austin's official slogan is The Live Music Capital of the World, the city has a vibrant live music scene with more music venues per capita than any other U.S. city. Austin's music revolves around the many nightclubs on 6th Street and an annual film/music/multimedia festival known as South by Southwest. The city also has a burgeoning circle of live performance theater venues such as: Zachary Scott Theatre Center, Vortex Repertory Company, Salvage Vanguard Theater, Arts on Real, Scottish Rite Children's Theater, Hyde Park Theatre, and Esther's Follies a comedy and magic show. The longest-running concert music program on American television, Austin City Limits, is videotaped on the University of Texas at Austin campus. Austin City Limits and Capital Sports & Entertainment run the Austin City Limits Music Festival, an annual music and art festival held at Zilker Park in Austin.
The Austin City Limits Music Festival also brings many tourists from around the nation.
The Congress Avenue Bridge houses the world's largest urban population of Mexican free-tailed bats. Starting in late February, up to 1.5 million bats take up residence inside the bridge's expansion and contraction zones as well as in long horizontal grooves running the length of the bridge's underside, an environment ideally suited for raising their young. Every evening around sunset, the bats emerge in search of insects, an exit visible on weather radar. Watching the bat emergence is an event that is popular with locals and tourists, with more than 100,000 viewers per year. The bats migrate to Mexico each winter.
Considering Austin's "Earth-friendly" persona, it is appropriate that the Austin Zoo, located in the Oak Hill neighborhood just north of U.S. 290, is a rescue zoo that provides sanctuary to displaced animals from a variety of unfortunate and often neglectful situations.
Austin also has several well-known swimming locations. These include Deep Eddy Pool, Texas' oldest man-made swimming pool, and Barton Springs Pool, the nation's largest natural swimming pool in an urban area. Both are spring-fed and maintain a constant temperature of 69 degrees year-round -- swimming in Barton Springs at Christmas is an annual tradition for many Austinites. Hippie Hollow, a county park situated along Lake Travis, is the only clothing-optional public park in Texas. Activities include rockclimbing, kayaking, swimming, exploring, and hiking along the greenbelt, a green, lush, long-spanning area that runs through the city. Hamilton Pool is a gorgeous and cool (temperature-wise) pool and wildlife park located about 30 minutes from the city and is strongly recommended by many locals.
Farmers markets are popular attractions, provided a variety of locally grown and often organic goods.
