Yellowstone is magical any time of the year, but winter is quiet and special. We explored it one January after a blizzard in a snow buggy but snowmobiles are also available for the more adventuresome. It is located largely in the northwest corner of Wyoming, extending into Montana and Idaho. Yellowstone is our first National Park and contains one of the largest high elevation lakes in North America centered over the largest super volcano (Yellowstone Caldera) on the continent.
