The entrance to Robber Baron Cave is a large sinkhole. It was developed as a showcave in 1926, and until its closure in 1933 some 300,000 people have visited the cave. The visitors were lowered to the entrance with a cable car. The enromous number of visitors is probably a result of its location right in the middle of San Antonio.
