No cars and totally peaceful walks complete with overlook after overlook on one of America's most scenic roads. Great for snowshoeing and cross-country skiing after a snowfall as well.
Skyline Drive is a winding highway that cuts straight through Shenandoah National Park. Being that we are in the south, you will find that the road is closed for the majority of the winter, and usually at the very mention of snow. The first few years of living here it was incredibly frustrating, then I realized that walking the road is one of the most scenic, peaceful hikes around. It's totally legal, and aside from a few other adventurous souls, you will have the entire park to yourself. Make sure to call ahead to find out about snow levels, as it can be much higher accumulation in the wintertime and you may need snowshoes or skis. You can park at any of these entry points: nps.gov/shen.
