These cruises travel through dramatic fjords carved by ancient ice, offering close‑up views of tidewater glaciers, towering cliffs, and abundant marine wildlife. Humpback whales, orcas, sea otters, puffins, sea lions, and porpoises are commonly seen, often at breathtakingly close range.

For cruise travelers, this is a high‑impact, bucket‑list adventure that delivers nonstop scenery and unforgettable wildlife encounters. It’s the perfect way to experience the raw, wild beauty of Alaska’s coastline.

Fun Facts

Kenai Fjords National Park protects over 600,000 acres of glaciers, fjords, and coastal wilderness.
The park is home to the Herman, Holgate, and Aialik Glaciers, some of the most active tidewater glaciers in Alaska.
Wildlife cruises often spot humpback whales, transient orcas, and Dall’s porpoises.
The cliffs along the fjords host thousands of nesting seabirds, including puffins and murres.
The park’s massive Harding Icefield feeds more than 30 glaciers.
Sea otters float in groups called rafts, sometimes with dozens resting together.
Orcas in this region belong to distinct resident and transient pods, each with unique behaviors.
Many cruises use smaller vessels, allowing closer views of wildlife and glaciers.

What to Expect During Your Visit

Your cruise begins in Seward’s small boat harbor and heads into the rugged coastline of Kenai Fjords National Park. As the boat travels through narrow fjords, you’ll see steep cliffs, waterfalls, and dense coastal rainforest. Naturalists onboard point out wildlife, explain glacier geology, and share stories about the region.

The highlight is reaching a tidewater glacier. The captain often stops the boat at a safe distance so you can watch for calving — when massive chunks of ice break off and crash into the water. The sound is thunderous and unforgettable.

Throughout the cruise, you’ll scan the water for whales, otters, porpoises, and seabirds. The experience is immersive, scenic, and full of photo opportunities. Most tours last 4–6 hours, depending on the route.
