Amtrak rail trip from Chicago to Glacier National Park to Seattle
Railbookers' Glacier National Park Express is a 10-day, 9-night independent rail package traveling onboard Amtrak from Chicago to Glacier National Park to Seattle. The trip starts in Chicago with an architecture sightseeing cruise on the Chicago River, continues to Glacier National Park for touring among its peaks and valleys, and finishes in Seattle. Because it is independent rather than escorted, travelers move between the three stops on their own rather than as part of a guided group. It suits travelers who want a long-distance train journey across the northern United States that pairs a major city, a national park, and a Pacific Northwest destination in one trip.
The same itinerary is listed by more than one company. Prices and inclusions can differ; compare before booking.
