Seward is the gateway to Kenai Fjords National Park, and the best way to experience it is from the water. Departing from Seward's small boat harbor, these cruises take you past towering glaciers, through fjords carved by ice, and into waters teeming with humpback whales, orca, sea otters, Steller sea lions, and puffins. Whether you have half a day or a full one, there is a Seward water tour built around your schedule.

The 4 Hour Kenai Fjords Wildlife Cruise is a great starting point, cruising the protected waters of Resurrection Bay where you will see sea lions at their haul-outs, seabird rookeries, and distant views of Bear Glacier, the largest glacier in the park. With a 4.75-star rating from over 1,100 guests, it is one of the most popular tours on Alaska Shore Tours. For deeper exploration, the 6 Hour Kenai Fjords National Park Cruise pushes into Aialik Bay to reach an active tidewater glacier where you may witness glacial calving. Rated 4.88 stars by nearly 1,800 guests, this cruise includes lunch and remains the bestselling Seward tour.

Guests wanting the most comprehensive experience can choose the 7.5 Hour or 8.5 Hour Northwestern Fjord Cruise, which venture further into the park's most remote bays. For a more intimate outing, the Small Boat Whale Watching and Sightseeing Tour runs a full 9-hour day on a smaller vessel for closer wildlife encounters.

Most Seward water tours check in at the Harbor 360 Hotel and include heated indoor cabins, outdoor viewing decks, and complimentary binoculars. Cruises operate from late May through mid-September, with whale sightings most common in June through August. Most cruises offer flexible cancellation up to 72 hours before departure, with some tours offering 24-hour cancellation.
