Seward's boat tours are the main way visitors experience Kenai Fjords National Park, and for good reason. Departing from the small boat harbor, these cruises navigate through glacier-carved fjords where you will see humpback whales, orca, sea otters, Steller sea lions, puffins, and active tidewater glaciers calving ice into the sea. Cruise lengths range from 4 hours to a full day, so there is an option for every schedule.

The 4 Hour Kenai Fjords Wildlife Cruise covers Resurrection Bay with sea lion haul-outs and seabird rookeries, rated 4.75 stars by over 1,100 guests. The 6 Hour Kenai Fjords National Park Cruise is the bestseller, pushing into Aialik Bay to reach an active tidewater glacier — rated 4.88 stars by nearly 1,800 guests and includes lunch. For deeper exploration, the 7.5 Hour and 8.5 Hour Northwestern Fjord Cruise venture into the park's most remote bays with multiple glacier viewings. The Small Boat Whale Watching and Sightseeing Tour offers a more intimate 9-hour experience on a smaller vessel for closer wildlife encounters.

All boat tours check in at the Harbor 360 Hotel and include heated indoor cabins, outdoor viewing decks, and complimentary binoculars. Longer cruises include a deli lunch. Boats operate from late May through mid-September, with whale sightings most common June through August. Flexible cancellation is available up to 72 hours before departure.
