This is really a trailer park that doubles as an RV park. It is a full hook up park, and is not very scenic or particularly clean. Stopped to check out the history at the Dakota Buttes Museum, which was closed, but the small library has a very good historical reference area in their basement. Mirror Lake has RV parking too, but not sure if they are full hookups. We camped here in a Fifth Wheel.
Amenities include water and electric, lake access, playground. Half of the sites would have utilities on wrong side. Mostly gravel sites. A few would have midday shade. No dump station. Mirror Lake is a small lake with idle only speed limit. Lots of playground equipment in the park. Nicely maintained. Good Verizon data and voice connection. Rate is $20 for water and electric. No hookup is $10. No TV available. We camped here in a Motorhome.
