If you are not sure about your travel route, download a Rocky Mountain brochure online and read more about the locale. You should also research the cities where the train stops. This will give you more of an idea what to expect and assist you in choosing the right travel route(s). In addition, you should also consider when you will be traveling. Some areas, for example, may tend to flood during the spring because of the snow melt.    Circle Journeys, offered by Rocky Mountaineer, allows you to combine routes and personalize your train travel experience. Don't make any definite plans before doing some online research first. That way, you will better know what to anticipate. You can also determine what sites and attractions you want to visit before, during, or after your journey.
