This 105-mile trail winds its way along the entire length of Shenandoah National Park, through the Blue Ridge Mountains of Virginia between the I-66 and I-64 freeways. Drivers spend their time tunneling through dense trees, then breaking out into breathtaking vistas at every bend in the road. While this road is filled with some legendary twists and high-speed sweeping turns, the speed limit is 35 mph and strictly enforced, meaning driving this stretch is all about handling over speed and can give drivers without performance cars a chance to get in on the action. During the foliage season (usually late October–early November) it's particularly crowded – for good reason – so spring and summer are better for cruising. Be prepared to brake for animals – the park has white-tailed deer, black bears, turkeys and all kinds of other critters that like to cross the road.
