Easy access and nicely laid out.  Being able to ditch the car and walk to hikes, the lodge and lake was so nice after a long drive.  The campground must be full from day one that it opens in the spring, but there is plenty of privacy.  If you have a larger trailer, some of the spaces required some expert level maneuvering to get into, but everyone managed to do it.  There was recycling available at the rubbish bins, so we were happy to unload them there.  Didn't see a lot of wildlife inside the campground, but enjoyed seeing the bison on the far side of the park.  Easy drives around the area and up to Mt. Rushmore and Crazy Horse.  We were in a minivan, so we fit easily through the smallest tunnels on the road.  I am not sure about our F250, and certainly NO motorhomes.  We plan to go back eventually and would definitely camp here again.
