Great place, especially in the fall!
We were here last fall and the colors were simply gorgeous. It was quite chilly in the morning and evening/night, so pack warm clothes! It's isolated, beautiful, and has clean, easily accessible restrooms. There's also potable water spigots. The sites aren't very private, but there's isn't that many sites so it balances out.
While 4x4 isn't required, I definitely wouldn't take any larger vehicles or tiny cars this way. The road is steeply inclined and bumpy.
We had a great time and would definitely stay here again!
