Is there a map showing the location of specific campsites anywhere?

I am guessing he wants a map before he gets there. Sorry to say, the map of this place was lost when Recreation.Gov "upgraded" their site last year. The campgrounds are supposed to update maps but MANY, like this one, have not. If you want an RV slot, I like the very last one on the left down by the lake. Sorry, I cant remember the number. Call the hosts. Remember, this is a primitive site - a very nice one but primitive. It is very close to Mount Rushmore and very nice for the 13 bucks we paid with Access Pass. If you want bells, whistles, and WIFI go to the crowded RV Parks and throwdown the BIG$$$. https://www.campsitephotos.com/campground/sd/horsethief-lake-black-hills-national-forest/

Recreation.gov shows all of the sites and availability if you select the dates you need.

Yes at the entrance and further at the lake
