The Bats at Congress Avenue Bridge
Austin is home to the largest urban bat population in the world, with as many as 1.5 million Mexican free-tailed bats taking up residence in the capital city every year. Every night starting in late March and continuing through fall, locals and visitors congregate all along (and underneath) Congress Avenue to watch the bats take flight from under the Congress Avenue Bridge for their nightly feeding ritual. On hot nights (with no rain), right around sundown, don't miss the incredible opportunity (for photographers, families, and nature lovers alike) to witness this natural phenomenon set against the backdrop of the downtown skyline.
