This is one of our favorite routes through Northern Virginia. We typically start out at 55 where it meets 15 and take side roads down to 17 until it connects to 211.
There's a wonderful section of tight technical but well graded switchbacks on 211 as you approach and cross Skyline Drive.
We usually have lunch in Luray and from there head up to Route 675 which is a series of switchbacks the carves it's way up the side of the mountain. There are wonderful vistas as you go up. Very pretty.
From there you catch Fort Valley Road which goes on seemingly forever as it winds it's way through this magical looking valley of pristine farms and old buildings. It eventually narrows to a tight state park road that follows a roaring creek bordered by steep canyon walls in a deep wood.
We typically make our way to the Starbucks in Front Royal before taking the Superslab back home. Sometimes we'll take 55 for some local color as it winds it's way seemingly through towns that time forgot.
The best sections are tagged in yellow.
