Turns out those antique, seal sinew and whale blubber snowshoes mounted on the cabin wall offer a great alternative to traditional downhill skiing. Modern snowshoes are easy to wear, lightweight and help you walk easily atop snowfall, and they're usually available to rent at your local outdoor store. The sport is a great activity for anyone looking to keep in shape through the winter months, with snowshoers burning on average 600 calories per hour.
If you're looking for snowshoeing in the Western states, try South Lake Tahoe's historic Camp Richardson Resort, which features hundreds of acres of specially marked trails for snowshoers of all levels, plus on-site rentals at the Mountain Sports Center. You'll get the chance to snowshoe right on the banks of Lake Tahoe, and kids 12 and under get a free trail pass.
For folks on the eastern seaboard, try New York's Garnet Hill Lodge and Resort in the Adirondack Mountains. Known for its well-groomed snowshoeing trails for beginners and experts, Garnet Hill Resort offers snowshoe rentals, cross-country skiing, hiking and even dogsledding. Keep in mind that between Thanksgiving and April these otherwise immaculate trails are usually hidden beneath 125 inches (!) of snowfall, so plan to do your winter sports here earlier in the season to avoid losing your vacation to inclement weather.
