Seabourn is once again sailing to Alaska after 15 years.

The Seabourn Sojourn sails the Last Frontier on an Ultimate Alaska cruise to begin a season of 11-, 12- and 14-day voyages. Cruises depart from Anchorage, Alaska, or Vancouver, British Columbia.

“Our return to Alaska offers a unique opportunity for Seabourn to do what it does best: share the highlights of an extraordinary destination, from postcard-perfect mountains and glaciers, to picturesque frontier towns, to onshore experiences and guided tours today’s luxury traveler seeks,” said Richard Meadows, president, Seabourn. “Like our guests, we’ve been counting down to this season. We’re going to offer an Alaska experience with no compromises — an ultra-luxury hospitality environment combined with adventurous off-ship experiences.”

The Alaska itinerary includes favorite ports of call, Inside Passage sights and the line’s signature Ventures by Seabourn program. Classic destinations extend to Juneau, Ketchikan and Sitka, while option experiences include expedition team-led kayak and zodiac tours.

The intimate 458-guest ship navigates areas not accessible to larger cruise ships, including remote gems like Alert Bay and Klemtu — a town populated by less than 500 Kitasoo Native Band residents and exclusive to Seabourn guests. Other highlights include the forests of the Inside Passage, glaciers and humpback whales of the Kenai Fjords and UNESCO World Heritage Site Glacier Bay.

Complimentary extras include cruise line-branded all-weather jackets and signature experiences like Seabourn Conversations with guest speakers and Caviar on the Ice deck party.
