Lewis & Clark Caverns – Less than an hour west of Bozeman, Montana.
We were looking for something to do while we waited a couple of days for the rest of the family to meet us in Bozeman to head into Yellowstone.
There are guided tours from May 1-September 30. You hike to the top entrance, then exit through a lower cave. The entire tour is 2 miles and lasts 2 hours.
It was a really beautiful cave and the tour guide was excellent! I would recommend this as a great introduction to caves for anyone.
There is some sliding and squeezing.
