According to experts, Austin is home to the largest urban bat colony in North America. Approximately 1.5 million bats have made the Congress Avenue Bridge their home. The bats settled here after a renovation of the bridge in 1980 created crevices that were perfect for bats to take refuge in against predators. Every spring the Mexican free tailed bats migrate north to the bridge to give birth and raise their offspring. Come summer time, the bats can be seen each evening at dusk as they emerge for their nightly excursions to rid the city of pesky insects before heading back to central Mexico in the fall.
It's nearly impossible to be unimpressed by the nightly mass exodus. Travelers can catch a glimpse of where the bats make their home by taking a sunset cruise from companies like Capital Cruises and the Lone Star Riverboat that are offered March through October. Visitors and locals alike who have taken the time to go watch the bats say it's a interesting sight to see if you have spare time on your hands.
The Congress Avenue Bridge is located southwest of downtown Austin in between the Colorado River and Lady Bird Lake.
