Alaska’s wildlife includes five iconic large mammals:the bear, the caribou,the moose, the wolf, and the Dall sheep. The ocean is home to humpback whales, orcas, otters, and seals. The skies are home to nearly 400 species of birds, including the bald eagle and the puffin. The best time for birdwatching is from June through September. This guide links each species to the best sites and activities for observing it.
Alaska is one of the last places where nature still reigns supreme. Watching a bear catch salmon in a river, hearing a whale’s breath in a fjord, or coming across a moose while hiking a trail is an integral part of the journey. Wildlife here is never just a backdrop, but a living, unpredictable reality.
This guide serves as a starting point for planning your wildlife viewing. It covers the three main categories—terrestrial wildlife, marine life, and birds—links each species to the best regions for spotting it, and suggests activities in Alaska for observing them.

Alaska’s Large Land Mammals
Alaska is home to remarkable terrestrial wildlife. Five species are emblematic of this wildlife, along with more elusive predators such as the lynx and the wolverine.
1.Bears, from Grizzlies to Kodiak Bears
Bears are the stars of Alaska’s wildlife. There are several types: the brown bear, the interior grizzly, the black bear of the forests, and the Kodiak bear—the largest subspecies in the world. The best places to seethem are Katmai National Park and its Brooks Falls, Lake Clark National Park, and Kodiak.

Denali National Park is home to all five of Alaska’s major mammals. Here, you can spot caribou in herds,moose—the world’s largest deer— wolves, and Dall’s sheep, recognizable by their white coats, on the ridges. Wrangell-St. Elias and Gates of the Arctic National Parks also offer wonderful opportunities to see these animals.
Marine and Coastal Wildlife
Along the coast and deep within the fjords, wildlife takes on a whole new character. Wildlife viewing at sea is often one of the highlights of a trip to Alaska.
3. Humpback Whales and Orcas
Humpback whales migrate every summer from Hawaii or Mexico to feed in the cold waters of Alaska, while orcas patrol the fjords. Kenai Fjords National Park, accessible from Seward, and Juneau are the best spots.
All the details are in our guide towhale watching.
4. Otters, Seals, and Sea Lions
Closer to the coast, you can see sea otters floating on their backs, seals and sea lions resting on the rocks, as well as Steller sea lions. Beluga whales are found in Cook Inlet, nearAnchorage. Terra Alaska takes you out to sea aboard small boats carrying 6 to 12 passengers, bringing you as close as possible to the glaciers.
Birds: Alaska, a Global Aviation Hub
Every year, millions of migratory birds pass through or nest in Alaska. With nearly 400 species recorded depending on the season, the region is one of the world’s largest migratory hubs.
