"Just 75 miles from the nation’s capital is 200,000-acre Shenandoah National Park with more than 500 miles of trails. Its most popular, the Old Rag area, requires reservations, but is well worth the effort, with daring scrambles and peaks that “make you feel like you're on top of the world” the park says. Next up is the easy, but rewarding, Stony Man hike, a 1.6-mile trail with Shenandoah Valley, and Massanutten Mountain views. It’s followed by the 1.7-mile moderate Hawksbill Mountain hike to the park’s highest peak, the 5.1-mile strenuous Overall Run Falls trail to its highest waterfall, and the Whiteoak Canyon area with three trails, from an easy 2-miler to a “very strenuous” 8.1-mile hike."
