Christel was our brilliant guide and gave us some great local information including details on wildlife, history and where to go. We meandered down the lake on our kayaks to the bridge witnessing many turtles on the way. Then the bats came out and it was spectacular to witness, I will remember this for ever. My husband and teenage son were equally impressed. Christel provided great information on the bats too. If you are in Austin I recommend booking this trip as it was amazing to witness especially from the river. Thanks Christel.
