As the name suggests, this breathtaking train journey leads its passengers through the mighty Denali National Park. The Alaska Railroad's flagship train, Denali Star embarks on a 12-hour ride between Anchorage and Fairbanks via Wasilla, Talkeetna and Denali. Along the 365-mile (587km) journey, the train rushes past rivers and mountains and offers expansive panoramas of Hurricane Gulch from the top of a terrifying 296-foot (90.2m) bridge. It's all worth it for the views, though.
