No shore excursions are available on a pure Inside Passage cruising day — the experience is the ship sailing through the landscape.
Humpback whales, orca, Dall's porpoise, Steller sea lions, and harbor seals are regularly spotted from the ship's open decks. Bald eagles patrol the shoreline overhead.
Bring binoculars →Many Inside Passage itineraries include a slow pass through Tracy Arm Fjord or Endicott Arm, where sheer granite walls rise 3,000 feet and small icebergs from the Sawyer or Dawes Glaciers dot the water.
Check your ship itinerary →National Park Service rangers and ship naturalists give lectures on Southeast Alaska ecology, Tlingit culture, glacier science, and wildlife behavior — usually free and well worth attending.
