The road going up to these dispersed campsites was a little rough.  Definitely need an all-wheel drive car or 4x4.  Somehow these big RVs get up here but it's definitely a nail-biter.  We did it in a Subaru Crosstrek and it was sketchy, but we made it.  The view is incredible.  The campground hosts stopped by and told us to be careful because there were two grizzlies that lived in the area.  Also, the park rangers were issuing fines for unattended campfires.
