I visited here in April '22 to find the campground closed, apparently since October. While I have never camped here, I would definitely recommend this spot to campers who don't mind being off the beaten path. Some of the campsites have amazing locations, and even the worst ones look pretty good. Seems like some of the spots need some work (picnic tables getting to worn down, etc.) The bathrooms looked on the rough side, didn't go in.
Upside: Capitol State Forest is a paradise for bikers, hikers, horse riders, ATVs, dirt bikes... Definitely stay here to get away from it all for a few days with some fun recreation in the deal. Also be careful - you'll notice lots of signs related to firearms. There are plenty of gun ranges in the area; you're bound to hear them.
