Great site in the Black Hills. Book early to get a good site. The hike in sites are recommended if you don't want neighbors. We were at site 17 - a hike in site - felt almost like we were in the wilderness, but flush toilets and a full service lodge and camp store within walking distance. We were there in July with few mosquitoes and low humidity. Great stargazing. This is higher altitude than most of Custer State Park, so lots of huge boulders and pine trees.
