The loop is closed due to the road being washed out halfway through the south park. No campgrounds open in north or south sections. You can boondock in the Little Missouri Grasslands. I saw that on Campendium last week. We were just the August 8,9,10 2020
Curvey but doable
There is only one main entrance in and I wouldn't worry about that but some of the roads get kinda small maybe leave it in their parking lot but HIGHLY recommend going we just went for the 2nd time and were surrounded by wild horses
Yes I would call or go to website. They have a lot of information
Not sure sweetie. But you should give them a call
