Lots of great places to ride in the Valley. It is less than an hour from NOVA. Give a PM and I'll ride with you.
Try this route:
66 West to Markham - take Leeds Manor Road North to Rt. 17 North, West on Rt. 50 then about 2 miles take Rt. 601 North, pass Mt. Weather, stop at Bears Den and continue to Rt. 7. Take Rt. 7 West to the bottom of the mountain, then go south on Rt. 606 River Road following the Shenandoah, take Rt. 649 at the Y (about 6 miles) and go until you hit Rt. 50 again. Take 50 West a mile or two and turn left on Rt. 638 (Howellsville Road). Go 6-7 miles until you hit the Y at the store and bear right continuing on Howellsville until you hit the T at Morgan's Ford Road. Take a right and cross the Shenandoah over the single lane low water bridge. Morgan's Ford wll turn right and turn into Milldale Road, which will turn into Red Gate Road. Continue on Red Gate (it takes a sharp right) and hit Route 50. Take 50 West, to Rt. 17 South and back to 66.
This should keep you busy for a few hours and is a nice way to spend an afternoon. I have done it 100 times.
You will pass the secret Mt. Weather facility, the TWA 514 crash site, bears den, treasure island (great rope swing into the river), you are close to Dinosaur Land, and White Post that was surveyed by George Washington as a teenager.
