My husband and I were looking for good boondocking spots yesterday and we decided to check out this spot, after finding it on The Dyrt and a few other sites. It's definitely a beautiful place, and most of the road to the site is paved, but the road up to the actual spot is gravel, with lots of potholes and washboard areas, which would make it difficult for an RV. But the biggest issue for RVs is an area of the road that is very steep and immediately turns into a hairpin turn that we didn't even want to try in our 4x4, since the road is very thin and our SUV (a 2009 Nissan Pathfinder) is kind of thick. I'm sure it's probably nothing for people who are used to using their 4x4 for more than regular driving in the snow, etc., but it was too dodgy for us. There is no way that even a Class C rig would be able to take that steep incline and immediately do that sharp turn. And since there's nowhere to turn around in that spot, you'd have to back your rig down the incline and then quite a ways down the pitted, gravel road to get out of it. 

It's full of trees and seems fairly remote, but we had 5 cars pass us as we were backing away from the incline, so it's obviously a busy spot - you wouldn't be there alone, and this was on a Thursday.
