Paved road but you could get off of the interstate and go through Shoshone and Pahrump. There is a campground by the winery in Pahrump. Shoshone is at the south end of Death Valley. Once you get past Vegas there are trails and fishing lakes on the way from the interstate to Brian Head. Be aware that the dirt roads going to fishing lakes are well used, but if you take a road out from the back side you may have to do some road repair to get through. Fire danger will be extremely high. Downed wood in the Forrest may get under 5% h20. Basically that means that logs become match light. There is a Jeep trail that runs more or less along the bottom of the Cedar Breaks. I recommend it. Farther north is gobblin valley, robbers roost etc. Have a great time.
