The parkway runs from the southern terminus of Shenandoah National Park's Skyline Drive in Virginia at Rockfish Gap to U.S. Route 441 at Oconaluftee in the Great Smoky Mountains National Park near Cherokee, North Carolina. There is no fee for using the parkway, however commercial vehicles are prohibited without approval from the Park Service Headquarters, near Asheville, North Carolina. The roadway is not maintained in the winter, and sections which pass over especially high elevations and through tunnels are often impassable and therefore closed from late fall through early spring. Weather is extremely variable in the mountains, so conditions and closures often change rapidly. The speed limit is never higher than 45 mph (70 km/h) and lower in some sections.
Also make sure to take your time while driving on the parkway as there are many stopping points along the way that offer scenic vistas as well places to stop, hike, shop, and look around.
