From sundown mid-March to early November, check out the largest urban bat colony in North America known as the Congress Bridge Bats.
Watching the bats swarm from under the bridge at sundown is one of Austin’s most popular tourist activities, but we recommend you experience it at least once. At its peak, the swarm of bats is impressive. If you really want to experience the show, go down under the bridge. The bats fly over closely over your head and it feels like your being attacked.
