Skyline Drive, Shenandoah National Park, Virginia
One reason to try this road: The awesome names of the geological structures along it, including Hogback Mountain, Elkwallow Gap, and Rockfish Gap. It’s also 105 miles of curvy, climbing, mountain-high-inducing goodness fairly close to Washington, DC. It travels from Front Royal to Waynesboro, Virginia, with very few access points (carry food and water), and features a serious climb-climb-descend-climb-climb-descend rhythm, as well as occasional bear sightings. There are numerous pullout points that let you get a good look at the Piedmont region and Shenandoah Valley. And if conditions are right, you’ll be able to look out at a fog ocean — a cloud that’s been trapped in the valley by a mass of cool air.
