Skyline Drive runs 105 miles north and south along the crest of the Blue Ridge Mountains in Shenandoah National Park and is the only public road through the park. It takes about three hours to travel the entire length of the park on a clear day. The speed limit is 35 mph, so you can roll down your windows, feel the breeze and experience every curve and turn of this beautiful drive. There are nearly 70 overlooks that offer stunning views of the Shenandoah Valley to the west or the rolling Piedmont to the east.
