Watch From Above on South Congress Bridge

South Congress Bridge offers unparalleled views of the bats taking flight into the sky. When you arrive on the bridge, you’ll quickly realize that all the spectators waiting for the bats are only on one side of the bridge.

Views Beside the Bridge

If you want a view of under the bridge to see the bats in Austin leaving their roost, there are 2 areas next to the water that give you a great view. On the right side of the bridge, there is a small open grass area and on the left side is a concrete boardwalk that extends over the water. Both sides will allow you to see the bats, but they have pros and cons.

In my experience, the majority of the bats roost on the right side of the bridge near the grassy area. Even though the grass slopes down towards the water, and can get crowded, you get great views of where the majority of the bats emerge from the bridge. The downside of this is that trees block most of your sight to see them after they take off.

The newly built boardwalk is also a great place to see the bats, especially as they leave the bridge. Spectators will have a great view of the bats following the river and see them fly together in the sky. You’ll still see bats coming out from under the bridge, but the majority of the colony lives toward the middle and other side of the bridge.

Bring your Own Kayak or Paddleboard

• No permits necessary to enter the lake, and no cost.
• Use these access points to enter the water.
• For additional parking, you can use Zilker Park, Red Bud Isle and Auditorium Shores.
• No swimming in the middle of the lake. Best place to swim is in Barton Creek that connects to the lake.
• Dogs are allowed on the lake, but in the summer, you have to be mindful of the local bacteria reports. With high concentration of blue green algae, it has been known to kill dogs after drinking.

Pro Tip: The best time to see bats is when the climate is hot and dry because they will come out before it’s too dark to see them. Mid-May to June is very hard to see the bats because the females are getting ready to give birth. If you are booking a tour, wait until late June or afterwards to make the most of your experience.

You’ll also be raising against losing the light so after you’ve seen the bats, start slowly making your way back.

Relax as you travel smoothly across the water, enjoying the captivating sight of millions of bats taking flight against the backdrop of the setting sun, creating memories to cherish for a lifetime.

Insider Tip: Bring water! The summer is very hot, even in the evening time. The chairs are plastic and tightly squeezed in. If you have children who have a hard time sitting still, it may be a good idea to bring something small to entertain them with until the bats make their appearance. You can also challenge them to see how many turtles they can spot in the water or on the shore.

More Ways to See the Bats in Austin

If you’d like to go at your own pace, and maybe be on the water before sunset, consider renting a boat or board for the day. Be mindful of when the rental business closes and when their property will need to be returned to avoid late fees.

Get a Rental Kayak and More

For those who want to take their time and be on the water for several hours before ending the day seeing the bats, consider renting from a local outfitter. There are many companies that have rental options throughout Ladybird Lake. One of the great places to rent from is Rowing Dock ATX.

Rowing Dock ATX has everything from kayaks, paddleboards, and even peddle kayaks. One thing to consider when renting from an outfitter is the time that you will be expected to return the boat or board. Depending on the time of the year, the bats can be seen anywhere from 7:15 pm to 8:45 pm. After seeing the bats in Austin, you’ll then have to race back to the dock before the outfitter closes to avoid a late fee. Rowing Dock ATX closes at 8 pm each day, which is later than most other rentals. Another thing to consider is while paddling back to the dock you’ll be riding the current, which will help getting you to the dock faster.

If you have concerns about making it back on time after seeing the bats, call the rental business ahead of time. They will know what time the bats are coming out and whether or not you should pay for a tour instead.

In my opinion, take a tour first before renting equipment. When you go to rent, try in the late spring when the sun doesn’t go down as late, and you’ll have more time to return to their dock.

Rent Your Own Small Boat

When it comes to seeing the bats, and not wanting the chance of getting wet, a great idea is to rent your own boat. At Capital Cruises, you can rent out a peddle swan boat, a donut boat or even an electric, motorized Duffy boat. Call ahead of time and let them know that you wish to see the bats and they will recommend the best time to leave by.

They even have options to include dinner with your sunset, bat cruise. Learn how to create a memorable experience with friends or family while seeing the extraordinary bats in Austin.

When Can You See the Bats

The bats under the South Congress Bridge are migratory Mexican free-tailed bats. Arriving to Austin during the warmer months of the year, people can expect to start seeing them in the area in late March or April until October.

In April, if there’s been little rain, spectators can begin to see the bats. The peak time of the year is July to September. When the weather is, and has been, warm and dry spectators have a better chance of seeing them due to their hunting habits. Make sure to arrive at the bridge 30 minutes before sunset when they start to appear.

While they seek shelter under South Congress Bridge, the pregnant females will give birth to their pups. It’s difficult to view the bats in mid-May and June because either only the males will hunt, or they will hunt later in the night. I went to watch them in early June, and I could hear them, but barely saw anything.

As they slowly begin to exit the bridge, large groups will gather to fly in a tight unison. Staying together in a compact line, they follow the river headed south slowly heading high into the sky. From far away it looks like smoke. Remember that they are wild animals, and there is no guarantee set time when they emerge from the bridge.

A Local’s Favorite Way to See the Bats

After living in the Austin area for several years, I’ve had the chance to see the bats many times in many different ways.

Standing on South Congress Bridge is a great vantage point to see them travel together following the river. Make sure to grab a spot on the bridge where you face south. The middle and right side of the bridge normally has the most activity. This is also a great way to see them if you’re nervous to be around them.

My favorite experience was when I booked a tour with Live Love Paddle and saw the bats on a kayak from the water. I went with family and friends, and everyone described it as a magical and a memorizing experience. The only downside is that when you make your way back to the dock, you’ll be going against the current, and it will get dark faster than you expect.

No matter your preference on how you choose to view the bats, just make sure you don’t miss out on this amazing and memorable experience.
