Congress Avenue Bridge Bats

Up to 1.5 million Mexican free-tailed bats live under the Congress Avenue Bridge. It's the largest urban bat colony in the world, and they stream out around sunset. It's free, and kids never forget it. Mid-May to early July is maternity season, when flights often come after dark. The biggest shows are late July through September, when the pups start flying. Timing: March–October; best mid-March to early May and late July–September.
