Mt. Rushmore & Badlands-Must-See Suggestions

Lots of great suggestions here but I didn't see Reptile Gardens! A great location is near Hill City as it is central to almost everything mentioned. We left the camper for the day and went a different direction each day. We have stayed at the Rafter J. Bar (wifi, pool, etc) but we have also stayed at Horse Theif campground but very small sites and on the side of a hill so I don't recommend with a larger RV.

I just remembered this one, kids HAVE TO GO on the Presidents Alpine Slide in Keystone, best ever ride!
