Frio Bat Cave

View up to 10 million Mexican free-tailed bats, one of the largest colonies in Texas, as they make their ascent into the evening sky. This cave also provides the necessary elements mother bats need to give birth to and raise their pups each year. Hike to the top of the hill to witness one of nature’s most incredible spectacles. Check the sky for merlin, zone-tailed hawk, peregrine falcon, and red-tailed hawk, which hover just behind the crest of the hill to hunt the exiting bats. Around the cave you will see cave swallow, canyon wren, and rock wren.
