Lower Viewing Area Tour

    Cash or check only. Seats are filled on a first-come, first-served basis with a maximum seating capacity of 70 visitors. Reservations are not accepted. The activity tour fee for the lower viewing area is $5.00 per person regardless of age. This park does not have cash on hand and is not able to make change; please bring the exact amount of cash for payment.


    A close-up view of the emergence is one of the most unique experiences in nature. The flapping of millions of tiny wings is usually audible and often creates a light wind that can be felt by visitors in the lower viewing area. Many visitors also enjoy listening to the soft clicking sounds the bats use to communicate with each other. Lower viewing area tours are conducted Thursday through Sunday, May through October. An educational program is given about bats, with an emphasis on the fascinating life history of the Brazilian free-tailed bat (T.b. mexicana).
