In the crisp Alaskan air, you can view exquisite landscapes and seascapes and watch killer whales, sea lions, and seabirds pass by glaciers, fjords, and ice fields in the waters of Kenai Fjords National Park. Visiting the park by boat gives you a glimpse of the fjord estuary ecosystem, one of the rarest and richest assemblages of life on earth. Found only in five other locations around the planet (Chile, Norway, New Zealand, Greenland, and Antarctica), the fjord ecosystem results from the meeting of seawater and the freshwater that melts from glaciers. Boat tours to view this rare and pristine environment depart Seward's small boat harbor daily in the summer months. Several companies provide a variety of tour options, schedules, and amenities, with reservations available in advance. You can choose between full-day tours that venture out to the park's tidewater glaciers and half-day tours that stay in the more protected waters of Resurrection Bay, while still giving you a taste of the park's wildlife and scenery. In addition to boat tours, smaller charter boats are also available. Park Rangers provide narration on many of the cruises offered by Major Marine Tours and present daily programs at Kenai Fjords Tours' day lodge, located on Fox Island. Listening to these park rangers is a great way to learn more about the history and ecology of Kenai Fjords National Park.
