That is a nice ride, but to add I would take a right when you get to Harman and go into the Canaan Valley State Park and check out Blackwater Falls.
Been in that area many times since I am from the Shenandoah Valley area of VA.
But Skyline Drive is very nice too. Yes, there is a fee but the $10 motorcycle fee is good for that day and 6 days after. If you go that way, check out Luray Caverns.
