If you’re drawn to wild landscapes, raw nature, and unforgettable animal encounters, Alaska delivers in every way.
Often referred to as the Last Frontier, Alaska is one of the few places in North America where wildlife still roams free in vast, untamed wilderness.
For those passionate about wildlife observation, spotting Alaska’s “Big 5” offers both challenge and reward.
The Big 5 includes five iconic species: brown bears, moose, caribou, Dall sheep, and wolves.
Each animal represents a unique piece of Alaska’s ecological puzzle and seeing even one in the wild is a powerful experience.
This guide will help you identify where and when to look, how to stay safe, and what gear you might need for the best wildlife encounters.
Meet Alaska’s Big 5
1. Brown Bear (Grizzly)
Arguably the most famous of the Big 5, the brown bear is a symbol of Alaska’s wild spirit.
These powerful creatures can weigh over 1,000 pounds and are most active during the warmer months when salmon are spawning.
Where to Spot
Look for brown bears in places like Katmai National Park, Brooks Falls, and Lake Clark National Park.
These areas are known for bear activity, especially during salmon runs when bears congregate at rivers to feed.
Best Time to See
Late June through early September is prime bear-watching season.
July tends to be the peak for salmon runs, which boosts your chances of spotting bears actively fishing.
2. Moose
Massive, solitary, and often seen near water, moose are the largest members of the deer family.
Bulls can weigh over 1,500 pounds and carry antlers spanning up to six feet.
Their quiet strength and distinctive appearance make them a favorite for wildlife enthusiasts.
Where to Spot
Moose are fairly widespread across Alaska.
You may see them in Denali National Park, the Chugach Mountains, and even around Anchorage’s greenbelts and Kincaid Park.
Best Time to See
Moose are visible year-round, but dawn and dusk offer the best opportunities.
During fall, especially September, bulls are more active and easier to spot during the rutting season.
3. Caribou
Caribou, known as reindeer in other parts of the world, travel in large herds across the Arctic and sub-Arctic tundra.
Their seasonal migrations are one of the great wildlife spectacles in North America.
Where to Spot
Large herds can be found in Denali, Western Alaska, and areas within the Arctic National Wildlife Refuge.
The Western Arctic Herd and Porcupine Herd are among the most well-known.
Best Time to See
Spring through fall is your best bet, particularly during migration periods in late spring and early fall.
These times offer the chance to see hundreds moving together across the tundra.
4. Dall Sheep
With bright white coats and curling horns, Dall sheep are most often seen perched on rocky alpine cliffs.
Their agility and high-altitude lifestyle make them more difficult to observe, but also more rewarding.
Where to Spot
Head to Denali National Park, Wrangell-St. Elias National Park, or Kenai Fjords National Park.
Look high these sheep prefer rugged slopes and ridges.
Best Time to See
Dall sheep can be spotted year-round, but are more visible in summer months when snow has melted and the terrain is easier to traverse.
5. Gray Wolf
Elusive and intelligent, the gray wolf is perhaps the most difficult of the Big 5 to spot.
Wolves travel in packs and cover wide territories, which means sightings are rare—but unforgettable.
Where to Spot
Your best chances are in Denali National Park and Yukon-Charley Rivers National Preserve, especially in more remote areas far from heavy tourist traffic.
Best Time to See
Winter offers the highest odds due to snow-covered terrain that makes tracks easier to follow.
However, some lucky visitors may catch a glimpse in spring or fall as well.
Where and When to Spot the Big 5
Timing and location are everything when planning your wildlife encounters.
Consider building your trip around peak wildlife seasons
- June to September is ideal for bears, moose, and caribou.
- May to July provides long daylight hours for hiking and photography.
- Late summer to early fall offers more animal activity due to mating and migration.
- Winter months are best for tracking wolves but require careful planning and gear.
For maximum success, explore national parks, wildlife refuges, and backcountry areas with low human traffic.

Alaska offers a range of wildlife tours designed for enthusiasts like you.
Whether it’s a floatplane trip to a bear-viewing platform or a backcountry hike with a wildlife expert, these experiences provide a safe, structured way to observe the Big 5
