Holland America's 2023 Alaska has six ships, 14-day options

'We've offered Alaska exploration longer than any cruise line, we continue to have more Glacier Bay itineraries and we're the only way to see the Yukon combined with a cruise,' Holland America President Gus Antorcha said.

From April through September next year, sailings will operate on Eurodam, Koningsdam, Nieuw Amsterdam, Noordam, Volendam and Westerdam. Cruises sail round-trip Seattle and Vancouver, BC, or one way between Whittier and Vancouver.

'Great Alaskan Explorer'

In addition to weeklong itineraries, the line will bring back two 14-day 'Great Alaska Explorer' departures.

These journeys operate round-trip Vancouver aboard Nieuw Amsterdam (May 7) and Noordam (Sept. 17), calling at Kodiak, Whittier (Anchorage), Valdez, Sitka, Skagway and Ketchikan with Glacier Bay scenic cruising .

Sixteen different Cruisetours (formerly Land+Sea Journeys) combine a three-, four- or seven-day Alaska cruise with an inland exploration of Denali National Park. Holland America is the only cruise line that extends land tours into the reaches of Canada's Yukon Territory.
