Just to update this since the last review had it closed. The road leading up to the summit is back open, but it is ROUGH. I had just done Rock Creek's drive up to dispersed near Dillon and thought that was bad, but this was worse. 

You will not be able to get anything low clearance or anything you're towing that does not have independent suspension + high clearance (I dropped my 18' TT at Walmart and went to scout - glad I did) While I was 1/4 up into the climb, a Sprinter Van was stopped at what is probably the worst portion of the road. If you can make it past that first choke point, you'll pass a park then walk-in camp site on the left and then shortly after another camp spot on the right that is more van friendly. Both are not good for trailers. It is after those two sites the road goes from bad to worse.

If you have a Camper on a F350 or high clearance + tent, it has some of the best views I've seen at a park spot. It's worth the drive up there for pictures if you're curious, but I would unhook anything you're carrying before doing so.
