I think it is one of those places that you should see at least once. We went out there about 15 years ago, it was mostly dirt, corrugated road for most of the way. We arrive and are the only car out there, everyone else in a 4wd. It was September and about 45deg in the shade. Went and did the tour, had lunch (took out a loan for this) and thought about staying, but the heat had us back in the air conditioned car and back on the road. To this day, we still remember how hot it was, and all that rough dirt road we drove, and that we would probably never go back, so we were glad we had done it once. Saying that, it was still an interesting place to see.
