no reservation required.  There is always room to stay.  We were motorcycle camping the blue ridge parkway and camped here for the night.  There was a place to eat and drink not far down the road at Laurel Springs.

Love to escape to Mount Mitchell in the summer.  Highest temperature recorded was 81.   I've always built a nice fire during any summer night.  Never go without planning for a very cold night (or day for that matter).  Nice hiking trails to explore and onsite restaurant.  Make sure you make a reservation before coming.  it always books up in advance.
