1. Black Hills, South Dakota
South Dakota is more than just Mount Rushmore. The Black Hills, a heavily trafficked summer tourist destination, also has trails a-plenty for snowshoers and cross-country skiers.
The Black Hills National Forest includes designated snowshoe areas in the Spearfish area, including 6,000 explorable acres in Custer State Park. But for a real winter trek, look no further than the Centennial Trail. This grueling 111-mile track begins at Bear Butte Lake and heads south to Wind Cave National Park, passing seven lakes and the occasional free-roaming buffalo along the way.
