The Gallatin Gateway Inn is a Spanish-stucco style railroad hotel at Gallatin Gateway, Montana. The hotel is one of the "Historic Inns of America." The Gallatin Gateway Inn was opened on June 18, 1927. Constructed and operated by The Milwaukee Road (Chicago, Milwaukee, St. Paul and Pacific Railroad), the luxury hotel was reached by electrified railroad branch line that connected to the Milwaukee's main line at Three Forks, Montana. It was among the first hotels in Montana with telephones in every room, and offered travelers access to Yellowstone National Park. Park buses took passengers from the hotel to the park.
