After spending the night in Pocatello, Idaho, the next day and a half of our trip were focused on Yellowstone National Park, near the borders between Idaho, Wyoming, and Montana. The park is enormous, and most noted for its unique geothermal features such as the Old Faithful Geyser. There are also a lot of sweeping views of the countryside that make the park even more worthwhile of a visit. We spent the night in Gardner, Montana and returned to the park the next day to see a bit more. Then, we departed by noon in order to drive through Montana, back into Wyoming, and finally spend the next night in Buffalo, Wyoming.
