Formed about a million years ago, The Texas State Park Longhorn Caverns are otherwordly. This lesser-visited Texas cavern tucked away in the darling little County of Burnet is one of the most beautiful Texas State Parks. Now dry, thousands of years ago, there was an underground river that flowed through the limestone bedrock in this location. That limestone was eventually dissolved by water creating alluring caverns. They are beautiful!
