If your New Year’s resolution is to exercise more, then try breathing in the fragrance of pines while you take a long walk outside. Don’t let snow deter you. Simply strap on a pair of snowshoes and make your way through forests, along rivers, and up mountain trails. The sport’s recent surge in popularity stems from the ease of learning. Attach the snowshoes to your feet and chart your own course. Try any of these seven locales, all of them personal favorites.
