As someone who tries to disperse camp as much as possible, when I do need to stay in an established campground, Grey Cliffs is the kind of place I try to find. Tent camping only(small trailers, truck campers are fine, but no hook ups). I booked a spot here due to the remoteness of the park and being unfamiliar with the area. I was arriving late and for my first night I didn’t want the stress of looking for dispersed camping(although, after dispersed camping the rest of my time around Great Basin, I now know I would have had no issues finding free spots).
I didn’t explore past my loop, loop A, but the spots were well spaced out, and all under the shadow of the Grey Cliffs. It was very relaxing, and no noise from generators.
