Robber Baron Cave is one of the most significant of the over 500 Bexar County (San Antonio), TX caves.  It is the longest known cave in the county with nearly a mile of mapped passages.  This cave has many interesting features including a large sinkhole entrance, a geologically complex two-dimensional maze of passages, a rich history including a period of commercialization, and several unique species, two of which are federally listed as endangered.  Long managed by members of the Bexar Grotto and acquired by the Texas Cave Management Association in 1995, Robber Baron is now protected as a karst resource to not only preserve its unique biology, geology and history, but also to provide a place where people can learn about and experience the underground environment.
