Thanks Herb,
There are two main roads into Sublime Point. We came in down what they call the forest road from FS road 223 to the North. That is the longer way in but the road is not as rough. Your Excursion would have no problem. A couple light pine branches briefly touched my Karavan but were soft and caused no damage. 99% of the road is no challenge at all and runs through some beautiful high country forests.
The other way in is on what the locals call the "service road" and comes in from the East just above where you stop to get your back country permits. I didn't take that route but my friend drove out that way and said it was pretty easy too.
If you go I would recommend taking a chain saw. We drove through dozens and dozens of downed trees that had been cut to keep the road open. The rangers said the trees fall like match sticks out there when the winds get high. The first guy that came in the service road on Wednesday night had to cut through a tree to get in. It would not be fun driving in there clean and then run into a fallen tree trying to get back out with no chain saw. :elkgrin:
By the way, there are only two camping spots on the point that require back country permits. We didn't know that and just got lucky they were available. Reserve them ahead if you plan to camp out there.
