Natural Bridge Caverns

San Antonio, TX · Texas Hill Country$$Cavern tours from $25 for adults; parking $10

About

Four college students went looking for passages off a sinkhole in 1960 and broke through into the largest commercial cavern in Texas, named for the 60-foot limestone bridge arching over its mouth. The Discovery Tour drops 180 feet into rooms hung with 6-foot soda straws, sheets of cave bacon, and chandeliers and columns that climb past 40 feet, with an underground stream still feeding the formations grain by grain. Book the 9am Lantern Tour to walk it the way the discoverers did, lit only by the swing of a handheld flame.

The Park Service runs eight of these 22 caves, and most of the rest are commercial show caves at $23 to $36 an adult. If you only pay for one, make it Ruby Falls: you ride an elevator 26 stories down inside Lookout Mountain and walk to a 145-foot waterfall.
