This place was hard to find - I almost gave up. The GPS directions and coordinates on this app are both wrong. Take Warm Slough Rd off 4000 N. Ignore the no trespassing signs- they refer to the land on either side of the road. You can also search "Warm Slough Campground" in google maps. There is a smaller campground at the end of the road, and a larger one with pit toilets if you hang a right at the brown sign with the various camping rules.

Lots of options with fire rings and tables. Really nice and peaceful once you find it :-)
