Circle 10 Campground is a Good Sam club
a bit outside of Badlands National Park with free Wi-Fi Internet access, which was not secured but came in at sites and worked fast. The campground is open year-round, but it is dry camping during the off-season. Season is from May 20th, 2016 until September 14th, 2016. Cost on the night the two RV Gypsies were here was about $38 a night with Good Sam discount for full hook-ups. No TV. There was a bit of road noise at night.
The Circle 10 RV Park can handle most sized RVs, and sites are provided with basic power and water. Full service sites are also available, providing higher electric capabilities as well as sewer hookups.
There was a guest laundry room, indoor showers, restrooms, and a pool but the two RV Gypsies did not use any of those amenities.
