Jewel Cave is the third longest cave in the world - over 181 mapped miles, with much more exploration opportunities available. There are several tours offered, (one which I mentioned on Day 8 - 11 under the "RV Adventure" tab on this website.)
Outside the Jewel Cave National Monument building sits this little torture chamber (if you don't like tight places). The crazier tours are four hours or more, but the cave gets so small, you have to fit through this space before joining the tour to make sure you don't get stuck in the cave. No thanks!
This space is 8 1/2 inches high by 24 inches wide. You must be able to wriggle your body through this space to go on some of the cave exploration tours. Visions like the one below, however, are highly motivational.
