With more than 3,000 miles of trails in Montana and 1,300 in Wyoming, snowmobilers have a vast winter playground to explore. Though rental shops are plentiful, machines are in high demand, so you're wise to make a reservation well in advance. Though snowmobiling doesn't require an extreme level of physical fitness, you have to be able to adequately handle the snowmobile and be well versed in safety measures because avalanches are common in the areas some of these trails traverse. Best bets for snowmobiling in Montana: West Yellowstone and the Seeley Lake Valley. In Wyoming: Yellowstone National Park and the surrounding national forest lands, depending on whether a long-looming ban ever becomes law.
