Kenai Fjords National Park cruise from Seward: where the boats reach

Kenai Fjords is a park made of ice and the water it fell into. The Harding Icefield sits on top of the peninsula, and the glaciers that drain it run down the valleys until, on this coast, they reach the sea and keep going. Those are the tidewater glaciers — ice that ends in salt water rather than in a gravel plain — and they are the reason the day is spent on a boat. You cannot walk to them. There is no road along that coast at all.

So a cruise out of Seward is the park. The boat leaves the small-boat harbour, runs down Resurrection Bay and turns along the outer coast into the fjords themselves. The listings name Aialik and Holgate as the glaciers the boats work towards, and both are approached the same way: the vessel eases in, the engines drop, and you sit in front of a wall of ice waiting to see whether a piece comes off it. Calving is the word the listings use, and it is the single thing most passengers came for. Nobody can promise it on a given morning, which is why time in front of the face matters more than anything else you can buy.

That is what the extra ninety minutes is really about. A six-hour cruise — $265 or $267 — gets into the park, reaches ice and comes back. $297, at seven and a half, lists two active tidewater glacier stops rather than one, so the odds of watching ice fall are doubled and the run along the coast is longer. $271 sits at seven hours on a smaller boat and lets the captain read the conditions on the day before choosing between Aialik and Holgate. Same park, same harbour, three different depths into it.

There is one piece of the park that plays by other rules. Exit Glacier comes off the same icefield, but it ends on land on the road side of the peninsula, and it is the only glacier in Kenai Fjords National Park you can reach by car. It is also invisible from every sailing here. That surprises people who booked a cruise on the strength of a photograph of it, so treat the two as separate halves of an Alaskan itinerary: a morning on the water for the tidewater ice, and a drive to Exit Glacier for the one you can stand near. And remember the season: these cruises run May to September, and nothing sails in between.

Four listings on this site sail into the national park, and they carry 1,416 of the 1,854 reviews on the whole site between them. Here is what each one is.

$297 — 7.5 hours, our top pick. The longest run into the fjords available here. A stable, high-speed catamaran, a captain who narrates the park as you cross it, and stops at two active tidewater glaciers with the opportunity to see a calving event at each. The listing names orcas, humpbacks, sea otters and sea lions among the wildlife. Binoculars to use on board, a shuttle from the railroad depot, coffee, tea and water, and a deli lunch with a turkey, roast beef or vegetarian sandwich. 391 reviews at 4.9.

$265 — 6 hours, the lowest fare into the park. The most reviewed listing on this site: 851 reviews at 4.9. A large, stable catamaran through the scenery of Resurrection Bay, out to the towering tidewater glaciers of the Gulf of Alaska, watching for whales, sea otters, sea lions, puffins and seals. A captain guide, binoculars, hot drinks, the same deli lunch, and local beers available to buy on board. If six hours is the day you have, this is the tested version of it.

$267 — 6 hours, with a wildlife guide. A spacious but cosier vessel and a dedicated on-board wildlife guide, taking in the seabird rookeries of the Alaska Maritime National Wildlife Refuge alongside the glaciers, with the geology of the Harding Icefield and the fjords explained as you go. A hot lunch — a Southwest chicken burrito with tortilla chips — and the Alaska SeaLife Center donation and Seward fees inside the fare. 149 reviews at 4.9.

$271 — 7 hours, the captain picks the route. A small-boat day where the route is decided on the morning for the conditions, working towards ice calving at Aialik or Holgate Glacier, through Resurrection Bay and the Alaska Maritime refuge, looking for whales, puffins and otters with expert guides. Hot lunch on board and all fees and taxes included. It holds 5.0 across 25 reviews — the shortest record of the four, and an unbroken one.

And what the neighbouring harbours are. If a listing sails from Valdez, Whittier or Girdwood, it is not a Kenai Fjords National Park cruise, however good the glacier is. $180 and $200 are Prince William Sound out of Valdez; $260 runs to College Fjord from Whittier; $389 and $406 reach Portage and Spencer from Girdwood. Worth knowing before you book, not after.

Book $297 if the ice is the point. Seven and a half hours, two active tidewater glacier stops, a captain narrating the park, binoculars, drinks and a deli lunch. 4.9 across 391 reviews. Two glacier faces rather than one is the strongest reason on this page to give up ninety minutes.

Book $265 if six hours suits the day better. The lowest fare into the national park, the longest review record on this site at 851, and the same water: Resurrection Bay, the tidewater glaciers, the whales and otters, with lunch served on board.

Book $267 if you want a naturalist, not just a view. Six hours with a wildlife guide aboard, the seabird rookeries of the Alaska Maritime refuge, the Harding Icefield explained, and a hot lunch. 4.9 across 149 reviews.

Book $271 if you prefer a small boat. Seven hours with the route chosen for the conditions, aiming at Aialik or Holgate, guides who know the refuge, hot lunch and all fees included. 5.0 across 25 reviews.

And if Seward is out of reach: $260 is eleven hours to College Fjord from Whittier or Anchorage with a meal on board, and $180 is six hours to the retreating Columbia Glacier from Valdez for the lowest fare on the site. Different fjords, same kind of morning.
