We arrived late in the afternoon, having experienced problems with our reservation elsewhere. Custer Mountain had a spot for us available, for all 4 nights we had hoped for. The location is great, located between the town of Custer and the western entrance to Custer State Park. Very convenient! The price was reasonable for a full-hookups site (we were told all sites are full hook-ups). The staff was friendly and helpful. One thing nice and different from most campgrounds - they picked up trash every morning around 9AM if you left it out. And one important thing for us - it was quiet! A little highway noise, but no rowdy campers. We really enjoyed our stay, would recommend it to others, and will stay here again when we next return to the Black Hills.
