Babies are safe if well supervised by their parents
The cave actualy was dug going gradually uphill. I felt very safe going thru the tour and highly recommend it!
It's very walkable and relatively easy to navigate
Yes
Yes, if you wear them on the front of you. Most mines and caves in the Black Hills don't allow back carriers, so babies don't hit their heads on low ceilings!
Yes, very safe
I would say yes but you can't take a stroller. A baby bjorn would work, just put it on the shorter person in your party.
