​OUR CAMPING ADVENTURES

The main attraction, the Devil's Sinkhole, is a National Natural Landmark that houses one of the state’s largest colonies of Mexican free-tailed bats. This enormous vertical cavern is thought to be the largest single-chamber cavern in Texas. The opening is a shaft approximately 50 feet wide that drops 140 feet into the cavern. Here, the shaft balloons out to a diameter of over 320 feet and reaches a total depth of over 350 feet. From late spring through early fall the sinkhole provides an amazing venue to witness over 3 million bats stream out into the evening sky.
