I wouldn't really call it difficult. Carpet Hill can be intimidating going down for some people. It's pretty steep and long. However, the trail is rough and rocky. So much so that I probably won't drive it again. 20 miles of non-stop bouldery road. The scenery is amazing though and I would say that it is worth doing at least once. I would definitely recommend a second vehicle also, it's pretty remote if you have problems.
