This National Natural Landmark is located eight miles west of a small city near called Sonora. Because of its calcite crystal formations and rarity of helictites, the cavern is considered to be a world-class cave. Bill Stephenson, the founder of the National Speleological Society, said the cave was the ‘most indescribably beautiful cave in the world, its beauty cannot be exaggerated, not even by a Texan.’
The formation of the cave is said to have occurred between 1.5 to five million years ago. The cave is a constant 71°F, but feels like 85°F due to the humidity. During a tour, you can go 150 feet below the Earth’s surface and be mesmerized by all the formations underground.
There are many tours you can choose to take. The easiest of them is one where you can walk through about two miles, and a tour guide will tell you all about the crystals forming. There are more difficult ones where you can really get down and dirty with spelunking. Make sure to head over to the website, since some tours require advance booking.
The attraction also has a gift and souvenir shop for perusing and making purchases.
TIP: Tickets are cheaper if you buy them online.
