70. We spent 3 nights of Spring Break here in Scampsite #5, in the South Sulphur Unit, which is the bigger of the two units on Cooper Lake. (Technically, it's not called Cooper Lake anymore either, but the park is still called by the original name.) The sewage treatment center for the park is within park boundaries and is audible from the nearest campsites.
The South Sulphur Unit is huge: it has over 100 campsites, over 20 screened shelters, and 15 cabins, some of which are well-appointed. The equestrian camping area was very nice and located next to several miles of more challenging trails. There are multiple boat ramps and multiple fishing areas, one of which is a lovely boardwalk and pier between Bright Star Camping Area and Honey Creek Day Use Area.
Doctors Creek Unit is much smaller: only 24 campsites and 7 screened shelters, but shorter, flatter, easier and swampier (that day) trails. The campsites at DC have more trees than the ones at SS.
We hiked the Coyote Run Trail at South Sulphur; it had a nice variety of topography, frog ponds and stream crossings, and we startled a herd of feral hogs and saw 2 Pileated Woodpeckers fly over us.
At Doctors Creek we tried to hike the Cedar Creek East Loop trail, but it was so swampy that we bailed as soon as we possibly could and walked the South Loop trail instead.

The South Sulphur Unit is close to Sulphur Springs, which is the county seat. Sulphur Springs is a lovely little town with lots of shops and restaurants around the square and a brewery and a winery within walking distance. The square has undergone a revitalization in recent years; the public restrooms (there are 2 of them) on the square are one-way glass, so that when one is inside, one can see out but folks outside can't see in (we tried them out, for research purposes). The town was actually sued over them by an artist, but won the suit because theirs are actually functional, as opposed to just artistic, or so we were told.
