I haven't camped there but we rode up to the campground (and back) from the main highway a few years ago on a bicycle tour. Very scenic. IIRC the access road is winding and steep, but again I was pedaling. A friend had a close encounter with bear and cub on the descent! Hope it reopens in time for your trip.
Steep Road, last camped there in July 1992, pulling 13ft. Scamp with V-8 Ford Van.
Summer camped there first in 1985, very nice area for lots of family activity,hiking ,swimming etc.
By 1992 the White Water's had taken over. Never went back.
