Welcome to the Old Tunnel
Help safeguard this colony
Texas Parks & Wildlife Department acquired this property in 1991 to protect and preserve the bat colony. As more people come to see the bats, the possibility of disturbance is increased. This might cause the bats to abandon the roost. Biologists have learned much from research performed here at the Old Tunnel. You can help save the bats and our chance to enjoy the spectacular nightly emergence

• Refrain from throwing rocks or any other objects at emerging bats
• Do not shine bright lights (flashlights, camera flash, video lights) on the emerging bats
