Are there campgrounds in the vacinitu?

Yes, there is camping on the grounds.

Great to camp at Summit Point...not this weekend though after the inches of rain all week though.

You can camp at track. No electric or water hook ups except in pit area. Jefferson 500 cancelled this weekend at the point.

They'll usually let you camp right there at the paddock

Also a KOA in Harpers Ferry.

Yes, Watermelon Park is one that is close. It is near Berryville, Virginia.
