It would be easy to spend a week or more in the Black Hills exploring all the outdoor recreation, tourist locales, art, and culture, but if we can spend three days, we can get a good taste of all those things. If we’ve got that much time, we could spend one day in the southern Hills—Custer State Park and the surrounding area, one day in the Northern Hills—Deadwood and Spearfish, and one day in Rapid City and the Badlands. Our trip planner has more ideas for how much time you need.
