Depends on the season really
The Shenandoah valley has like 5 caverns , hundreds of camp grounds, thousands of miles of hiking trail and miles and miles of senic highways. That you will barely be noticed .
A fair amount but its so large you dont often bump into people unless at a campsite
Looks like around 1.2 million annually.
A lot. You will see cars backed up all the way towards to main road
So many at the time of fall season.
