Just a few minutes northeast of San Antonio lies a geological wonder that attracts tourists from around the globe. Natural Bridge Caverns, designated both a U.S. Natural Landmark as well as a Texas Historic Site, contains some of the most phenomenal cave formations in the country. Giant stalactites resembling enormous chandeliers and stalagmites that look like fried eggs are just a few of the more than 10,000 formations contained within this living cave. The caves are not wheelchair accessible. Special rates are available for groups of 25 or more.
