5-day Alaska rail and cruise trip from Seward to Anchorage
Railbookers offers this 5-day, 4-night independent rail package starting in Seward, Alaska. Rather than one continuous train journey, the trip combines a boat cruise through Kenai Fjords National Park and Resurrection Bay, where travelers can see glaciers, coastal rainforest and wildlife, with a scenic ride on the Alaska Railroad's Coastal Classic train on to Anchorage. As an independent package, travelers make their own way rather than following a tour manager. It suits travelers who want to pair an Alaska boat cruise with one named train ride rather than a multi-day rail itinerary, and who are comfortable planning their own days.
