Yellowstone in the Winter
Finally, don’t forget Yellowstone National Park in the winter. You can come in (but very limited) on snowmobiles. Mammoth Hot Springs, the park’s headquarters can be accessed by snowmobiles. And, the other two entrances that are opened all winter are the south entrance from Jackson, WY and the west road from West Yellowstone, MT. However, I use the term “opened” very lightly.
The park is not opened to vehicles – too much snow and no way to clear the roads. Instead, you stop at the two entrances (you must have reservations at Yellowstone National Park) and big snow coaches take you to the Old Faithful area. There is one hotel opened year round there, called Snow Lodge. I have never had a chance to visit Yellowstone Park in the winter but have talked to several people who have and they say it is a journey that should not be missed.
