We are staying 5 days (4 nights) in the Black Hills. Our cabin is in the Blue Bell campground in Custer Park. We will be there next week. It is going to be my husband and I with our three boys 13, 10, 8. I have discovered that Custer State Park is a bit out, I need help determining a good use of time for our visit. I would appreciate itinerary suggestions. Thanks for any help!
