Discovering Alaska’s Big Five: Land and Sea Wildlife Wonders
Alaska is the ultimate frontier for wildlife lovers, offering jaw-dropping encounters with some of the most iconic creatures in North America. Whether you're gazing across tundra plains or scanning the waves of icy coastal waters, you're stepping into one of nature’s grandest arenas. In Alaska, the term “Big Five” doesn’t just apply to land—it extends into the sea as well.
So what are the “Big Five” of Alaska? Let’s explore both the legendary land animals and their magnificent marine counterparts that every wildlife enthusiast dreams of spotting.
The Alaska Big Five – Land Animals
Originally coined by safari-goers in Africa, the term “Big Five” in Alaska refers to the five most iconic and sought-after land animals that travelers hope to see. Here they are:
1. Grizzly Bear (Brown Bear)

Planning Your Alaska Adventure
From Denali’s sweeping tundra to the dramatic fjords of Kenai or Glacier Bay, Alaska offers one-of-a-kind wildlife encounters. The best way to see both the land and marine Big Five is to combine a land-based tour (like a Denali National Park visit) with a coastal cruise or day trip along the Inside Passage.
Whether you’re watching a grizzly catch salmon mid-air or spotting the tail of a diving humpback whale, the magic of Alaska’s Big Five—on land and sea—is something you’ll never forget.
