We got the opportunity to visit Yellowstone National Park this winter. It is a fantastic time to go. Because of winter weather, they shut down the national park in early December, and there are only two modes of transportation into the park! Snowmobile or Snow Coach. We chose the snow coach option. The tour went into the west gate of Yellowstone, and we stopped to look at wildlife, geysers with the final destination being the Old Faithful geyser. We used Yellowstone Vacations to book the tour. If you are visiting the Big Sky area, it is totally worth the 1-hour drive to Yellowstone National Park.
