Austin - New Road Trip 2024
My next American trip is less than 48 hours away. I am super excited and actually have a night near Heathrow Airport to be able to be in Terminal Three and through security for the 08:10 departure to Dallas. Accompanied by my daughter for what has become an annual adventure since she was at Summer Camp and I would fly out and meet her for a holiday. We will be using MPC ESTA for the first time…

South Congress Bridge Bat Watching Guide
Austin is home to the largest urban bat colony in North America. Around 1.5 million Mexican Free-tailed bats live under the Congress Street Bridge from March to October emerge at dusk in a breathtaking display.
Austin's bats migrate every spring from Mexico and have made their home under the Congress Street Bridge by the thousands since 1980. Primarily female, the bats come to Austin to have their pups, usually in early June. They remain in residence under the bridge usually until mid-October, and each night they leave their roost to forage on the mosquitoes and flies and other bugs of Austin and its environs.
The bats normally emerge just before sundown and fly east to hunt for insects in the Colorado River valley. The south sidewalk of the Congress Bridge is my favorite spot. While other views are available, the Congress Bridge lets you see the columns of bats as they fly east down the river. The bridge vantage point also avoids the odor which can be intense. Arrive about an hour before sundown to claim a good spot. Also, take the time to read the education signs in the small park on the southeast bank next to the bridge.

Bat Watching Guide Austin Texas
Most people associate Austin, Texas with the outstanding music scene and industry that is there or the "Longhorns" of the University of Texas at Austin, however, there is something else incredible that resides in the heart of the city and that is a colony of over 1.5 million Mexican free-tail bats.
This is the largest urban population of bats in the world. Every evening these Mexican Free Tail bats surface to seek out insects and bugs. This curiously attracts 100,000 viewers annually. After harboring under the bridge for the summer, spring, and fall months, the bats head toward Mexico in the winter, which is even a more amazing site to see. I highly recommend watching the bats whether you live in Austin or are just visiting.
