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.If you head north towards Harrisonburg from Staunton and take US Rt 33 west you'll be on your way to the route I mentioned. Well worth it, I used to ride those roads every weekend on my sport bikes. One tip, there is an Exxon station in the middle of no where when you get through the mountains. Get gas. Lol
33 west to rt 220 south to rt 250 east. 250 will take you back to Staunton.
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.
