Known for its luxury Canadian Rockies train trips, The Rocky Mountaineer now offers a U.S. route from Moab to Denver through Arches National Park to Ruby Canyon and Colorado's peaks. The standard package takes two days and also travels in the reverse direction, but you can upgrade to the SilverLeaf Service package if you prefer more opulence and panoramic views.

From the windows of one of the beautiful heritage cars, travelers can enjoy views of cranberry bogs, sand dunes, and New England forests for 27 miles on the Cape Cod Central Railroad. There are several options from dining, wine and beer tastings, and guided excursion trains — and during the holiday season, try the Polar Express!

Enjoy views from New Orleans to Hollywood on this scenic ride across five states. If you book during high season, guides from the National Parks Services are on board to provide information on the beautiful scenery and history behind the featured destinations.

The Great Smoky Mountain Railroad is a great alternative to view the south, and the tracks go through areas that can be difficult (or even impossible) to access by car. Board at Bryson City, North Carolina, then travel along the Nantahala or Tuckasegee River, which both take approximately four hours — or try the Moonshine Experience or Fall Foliage trains.

An icon of the entire country, a road trip or hike might be the typical way to enjoy this part of northern Arizona, but it's definitely worth a trip on the Grand Canyon Train. One-day trips are like stepping back in time, complete with cowboys and music, and you can choose which era you'd like to ride in, with options stemming from the '20s to '50s.
