It is possible to enjoy the sights and sounds of Yellowstone without raising a finger -- except to write a check or sign a credit card voucher -- by taking one of the scenic snowcoach tours that originate at the south and west entrances, as well as at Mammoth and Old Faithful. One-way and wildlife-watching trips range from $27 to $60, while round-trips cost about $100 to $120.
If you've never seen a snowcoach, you're in for a treat. Don't be fooled into thinking that this distinctively Yellowstone mode of transportation is merely a fancy name for a bus that provides tours during winter. Imagine instead an Econoline van with tank treads for tires and water skis extending from its front, and you won't be surprised when you see this unusual-looking vehicle. The interiors are toasty-warm, with seating for a large group, and they usually allow each passenger two bags. They aren't the fastest, smoothest, or most comfortable form of transportation, but they do allow large groups to travel together, and they're cheaper and warmer than snowmobiles. They're also available for hire by groups at many snowmobile locations. Guides provide interesting and entertaining facts and stories of the areas as you cruise the park trails, and they give you opportunities to photograph scenery and wildlife.
