The road is not very rough at all and fairly wide. No problem with vehicles passing each other. Turns are not very tight and easy to maneuver. Turn arounds available. Some sites are tight but long. others are wide but short. I towed my 19' Airstream with my Nissan Xterra, so not very long.

The road in is fine. We have a 27 ft TT and had absolutely no problems. If you enter the first campground (sunset view) It's kinda tight in there. But Canyon View is very nice and wide, and if you go to the end of it, there is a loop to turn around without backing up

It’s paved to the visitor center but pretty narrow, you won’t want to drive quickly. I recall maybe one or two pullouts but there isn’t a ton of room. You can turn around at the visitor center. The campsites in the developed campground are not big. Our 25’ EarthRoamer would only fit into a few. The undeveloped campground, if it’s open, has much bigger sites, and is only a mile or two further. That road is dirt, but not super rough.
