What is it? The nightly flight of 1.5 million bats that live under the Congress Avenue Bridge.
Why go? It’s an Austin ritual to gather each evening—from late March through early fall after checking the "bat emergency hotline" for times—and watch the creatures come out to feed. Hop in a kayak and paddle under the bridge for a closer look. Each August, Bat Fest celebrates the little vampires with food, drink, bands and other entertainment spanning the length of the bridge.
