The best way to see Alaska is by rail, and this rail line proves it. Double-decker dome cars allow passengers to take in sights from multiple locations by stepping onto an outdoor balcony or settling in to a seat on the upper level’s interior space. Operating mid-May through mid-September, the railroad travels between Anchorage and Fairbanks, with stops in Wasilla, Talkeetna and the 6-million-acre wild land of Denali National Park.
