Most people think of summer when they think of Yellowstone - but winter has an equal appeal to folks looking for adventure.  The closest entrance to Big Sky is through West Yellowstone, which is about 50 miles south. From West Yellowstone you can enter the Park by snowmobile, snowcoach (a sort of bus or van on snow tracks or big snow tires), or by cross country skiing.  The amount of visitors allowed into Yellowstone by one of these modes of transportation is limited, so it is important to make advanced reservations.  We recommend Yellowstone Vacations as a tour company, check out their website for more information.

If you want to drive into the Park, the only entrance accessible in the winter by vehicle is through the North Entrance, at Gardiner, MT, which is about 120 miles away. From the North Entrance you can visit Mammoth Hot Springs, and drive through the Lamar Valley.
