Imagine standing on deck, crisp sea air brushing your face, dense emerald rainforest rising behind you, and snow-capped peaks towering in the distance. This is the wild, breathtaking setting of Admiralty Island, a place where dramatic landscapes and rich ecosystems converge to create some of the most rewarding wildlife viewing experiences in Alaska.
Whales in the Inside Passage: A Marine Spectacle
The waters surrounding Admiralty Island are teeming with life. In spring and summer, nutrient-rich currents attract a diverse cast of marine mammals, including humpback and orca (killer) whales. Humpbacks, graceful giants known for their impressive breaches, tail-slaps, and the mesmerizing bubble-net feeding technique, are frequent visitors here, especially where schools of herring or krill congregate. Orcas, with their stark black-and-white patterns slicing through the waves, may appear in sleek pods, slicing through the water with remarkable speed and precision. While there’s no guarantee you’ll spot them on every outing, many voyages yield sightings of these magnificent creatures playing, feeding, and interacting in ways that feel almost cinematic.
“Kootznoowoo”—The Fortress of the Bears
If the ocean is rich with life, the forested shores and river estuaries of Admiralty Island are equally compelling. The island’s native name, Kootznoowoo, meaning “Fortress of the Bears”, is no understatement. With an estimated 1,500–1,600 brown bears roaming its old-growth forests, river valleys, and coastal wetlands, Admiralty Island boasts one of the highest densities of brown bears anywhere on Earth, far outnumbering its small human population.
One of the most iconic wildlife experiences here is bear viewing at Pack Creek Brown Bear Viewing Area, located within Admiralty Island National Monument and the surrounding Kootznoowoo Wilderness. Accessible by floatplane, Pack Creek draws bears that come to feed on salmon returning to spawn, dig for shellfish in tidal flats, or graze in lush estuary grasses. With patience, you may see mothers teaching cubs how to fish, juveniles tussling playfully, or dominant males patiently awaiting their turn in the stream.
How to Make the Most of Your Visit
- Timing Matters: Bear viewing and whale spotting seasons overlap but are influenced by natural cycles—late June through August is peak for salmon-driven bear activity, while whale sightings can be excellent in spring and early summer as animals follow food sources.
- Respect Wildlife: Both bears and marine mammals are wild and powerful. Follow all safety guidelines, maintain respectful distances, and let expert naturalists or guides help interpret the behaviors you’re witnessing.
Beyond Bears and Whales
While bears and whales may steal the spotlight, Admiralty Island’s biodiversity doesn’t stop there. The island also supports one of the densest populations of bald eagles in the world, thriving populations of Sitka black-tailed deer, and a host of smaller mammals and birds. Every paddle through a quiet cove or walk along a forest trail offers chances to encounter the island’s rich tapestry of life.
