On March 27, 1960, four college students, Orion Knox Jr., Preston Knodell Jr., Al Brandt, and Joe Cantu from St. Mary's University in San Antonio began an underground exploration that ultimately would reveal the most extensive, largest cavern system in Texas. After hearing of an incredible 60-foot natural limestone bridge, which later became the caverns' namesake, the students asked landowner Clara Wuest if they could investigate what laid beneath their family’s ranch. On the cavers’ fourth expedition, they uncovered a long, narrow crawlspace that ultimately opened into 2 miles of virgin caverns. Today, their discovery is recognized as one of the world's premier show caverns.
Natural Bridge Caverns located between San Antonio and New Braunfels, Texas, offers year-round activities including multiple cavern tours, a maze, an aerial sky adventure, gemstone mining, restaurants, and shopping. Grounds offer several ideal settings for weddings, groups, and birthday parties. Christmas at the Caverns includes holiday light displays, carolers throughout the caverns, and a hill country hayride. Natural Bridge Caverns is owned and operated by the Wuest family and is a designated State Historical Site, National Natural Landmark, and is listed on the National Register of Historic Places.
