It sounded corny...watching the bats fly out from under the bridge. We did it anyway, and are so glad we did! It's nature! It's exciting! It's unique! For at least twenty minutes, you watch bats fly out from their home under the South Congress Bridge...streams and streams, over 750,000 in total. they form lanes and fly to the east and... More

Believe it or not, the Congress Ave Bridge in Austin is home to the largest urban bat colony in North America. There are between 750,000 to 1.5 million Mexican free-tailed bats in residence. It is a fantastic sight to see them emerging almost as a cloud to forage for the night.. The population is at its peak in August after... More

An awesome sight to behold. Between 750k and 1.5 mio bats leaving there "home" under the Congress Bridge to start there nightly hunt. Best way to see them is from a boat on the water, because you can het different views and get really close to the bats under the bridge. It takes between 1 and 2 hours for all... More

Very interesting to see millions of tiny bats take flight and dance over the water and up into the early evening sky. Nice to sit by the water at sunset while waiting for the event. If you get too close though...be prepared for a very unpleasant odor. Worth the trip!

Austin's home to the largest bat colony in Northern America and every day at dusk, they fly out from under the bridge! It's pretty cool seeing them fly out, definitely worth the wait! Make sure to get there early so you get a good spot! Best is to either be on a boat or stand in the little clearing by... More

I come here once every couple of years, and its always a fun sight to see. I like going at the end of the summer because the bat community is HUGE that time of year. Its crazy to see the number of bats flying out from under the bridge. I don't know how they all fit under there. We parked... More

but once or twice is enough. Did the first time from the bridge and was AMAZED at the number of bats that come out. Honestly looked like a biblical plague after they spread out into the sky. Did the next night from below where the atmosphere is a bit more festive. You have to do it if you're in town.... More

It was very windy the night we were there (April 9), and maybe that was why there were so few bats. I have seen photos of the masses, but we saw only a trickle. It still was a good experience to be out on the bridge with a lot of people at sunset. The best part were the white birds... More

Keep in mind the bats are only here in Summer time. A lot of people stand around waiting for the show at the wrong time of year.
