Whittier's proximity to Anchorage make a glacier cruise a great option as a day trip from Anchorage. The icy waters of Prince William Sound accessible from Whittier offer the highest concentration of glaciers in Alaska. Roundtrip transportation from Anchorage is available with the individual tour operators or with the Alaska Railroad. Excellent day cruises include the Prince William Sound Glacier Cruise and the 26 Glacier Cruise.
