Natural Bridge Caverns

Just a few miles from San Antonio, Texas are Natural Bridge Caverns, which are the largest commercial cavern in the state of Texas.  Natural Bridge Caverns contains several geological formations including stalagmites, stalactites, and columns. There are seemingly bottomless pits and underground streams here that will capture your amazement. Guided tours of Natural Bridge Caverns are offered for a small fee, and while you are here check out the Wildlife Ranch and the Watchtower Challenge.
