The RV sites are located at the corner of E. Centre St and Cambell St. The entrance is on E. Centre. There is no staff at the RV park. Pull in to any site, disconnect your toad, drive south on the interior dirt road with your toad, make a right turn and look soon for the office at 800 San Francisco Street. Go in, pay $30., get a tag telling the date you will be leaving. They will send a person to unlock your electric post. Same price, 30 or 50 amp. The person they send will know which sites are 30 and which are 50 amp. Important: call first to be sure a site is available. While only 5 sites were occupied when we stayed, if an event is scheduled, like a fair, then it is unlikely a site will be available. Office open M-F, 8 AM to 5 PM. GPS: since the RV park has no address, you can use 600 Cambell St., the address of a local business across the street. Once there, the park will be obvious. Use Exit 60 from I-90 and drive south looking for signs "Central States Fair Grounds. Very good overnight stop. No shade. Level. We camped here in a Motorhome.
We stayed overnight here to be close to a service location the next morning. It serves the purpose of an overnight stay; long pull-thrus, gravel sites, good power and water. Small trees, dead grass, a bit of road noise, and on the night we were there, lots of empty sites. Check-in is by phone and they'll send someone out to unlock the power box and collect the fee. Surprisingly, the rates do not change during the Sturgis Rally, although even then there were few people using the park. Convenient to the Freightliner dealer and Rapid City, otherwise there are much better places for just a few dollars more. We camped here in a Motorhome.
Used this campground because it was only $30 compared to most I called around here which was $60 and up. Some of the sites were on concrete but I chose a gravel site as it was closer to the showers. Was a good place for seeing the sights of Mt. Rushmore etc. The price is the only thing this campground has going for it. We camped here in a Travel Trailer.
