Congress Avenue Bridge Bat Tour, Austin, Texas
Crowds gather from March through October on the Congress Avenue Bridge to see a natural spectacle that has earned the resident bat colony celebrity status in Austin. Each night at dusk, 1.5 million Mexican free-tailed bats emerge from beneath the bridge, swirling like a black ribbon into the sky. For a unique perspective on the mass exodus, watch it from the water on a Congress Avenue Kayaks bat tour. With a small group of 10, you'll paddle under the bridge in sit-on-top kayaks. After encountering the bats, you can venture out on your own to see other sights on the water.
Details: The 90-minute kayak bat tour departs at sunset in season and is $30 for a two-person kayak.
Insider Tip: You can also watch the bats from the Four Seasons Hotel Austin's lobby lounge, which serves a "Batini" cocktail. Plan an August visit to coincide with the city's annual bat festival.
