Bat Season

You must have a bat-viewing ticket to stay in the park after 5 p.m. May 1 through Oct. 31.

Buy tickets in advance online or by calling the Customer Service Center. We do not sell tickets on-site. Bring printed tickets or a phone with email confirmation to show at gate.

Space is limited, so purchase your ticket early. We do not allow children under 4 years old at the lower area. The bat viewing areas and the trail to them meet ADA guidelines.

We do not issue refunds if bats are not visible.

For up-to-date bat emergence information, check Facebook, Twitter, or call the toll-free line at (866) 978-2287 (recorded message only). To contact us, email Old.Tunnel@tpwd.texas.gov. Plan to arrive an hour earlier than recent emergence times. 

To protect the bats, we do not allow camping, pets or smoking.
