I need some help finalizing our itinerary. We are staying in Keystone and would like to take one day to do wildlife loop, wind cave candlelight tour (booked in advance), iron mtn road south to north, and Mt. Rushmore, in that order. What would be our best driving route to accomplish these? Also, would it be better to book the 10:30 or the 1:30 cave tour? I don't have a good feel for how long it will take to drive from Keystone and complete the wildlife loop before the cave tour. This is only one of our days in the Black Hills. I've got our other days figured out.
