My wife booked this trip for her birthday. While we have seen the Congress Ave bridge bats from land, there is nothing quite like seeing it from the water. We started off around 715pm and took our kayaks to Barton Creek and back to the bridge to see the bats. While we did arrive about 10 minutes late for the start of the bat brigade, we did get plenty of time to watch them pour out of the bridge and over the trees on their way to feast. The sunset as we made our way up to Barton Creek was something else. Cody was our guide and was quite informative about the little spots around the lake, cool building facts and tips on where to eat and drink in the city. Definitely recommend doing the evening tour.
