Some time ago, we talked about the best Alaska Cruises for Whale Watching: humpback whales, orcas, gray whales and others. But, which other wildlife can you see on an Alaska Cruise? Choosing an Alaska wildlife cruise means stepping into one of the most incredible ecosystems on the planet. While you may book your trip hoping to experience unforgettable Alaska cruise whale watching, you'll soon realize that whales are only part of the story. Eagles, puffins, sea otters, harbor seals, black bears, and even mountain goats can all make an appearance along the way.
In this blog, we'll explore the incredible Alaska cruise animals you may encounter, where you're most likely to spot them, and how to make the most of your Alaska cruise wildlife adventure.
If seeing wildlife is at the top of your travel wishlist, an Alaska cruise is hard to beat. Unlike many land-based trips, cruises take you into remote coastal regions that are difficult to reach by road, giving you front-row access to some of Alaska's most incredible natural habitats.
One of the biggest advantages of an Alaska wildlife cruise is the combination of onboard wildlife viewing and immersive shore excursions. While cruising offers panoramic views and the chance to spot animals from the comfort of the ship, guided excursions take the experience a step further. Led by knowledgeable local experts, these tours bring you closer to Alaska's diverse ecosystems, whether you're exploring coastal forests, kayaking through quiet inlets, or visiting areas known for bear and bird sightings.
Together, these experiences create the ultimate Alaska cruise wildlife adventure, giving travelers the chance to appreciate Alaska's remarkable biodiversity from both the water and the shore.
From the comfort of your ship, you'll sail through protected waterways, glacier-fed fjords, and coastal habitats where alaska cruise animals thrives. In fact, many of the most memorable sightings happen right from the deck, so keeping your binoculars, and your camera, close by is always a good idea.
Whales
Whales are undoubtedly the stars of the show for many travelers. Depending on the time of year and your itinerary, you may see humpback whales breaching, pods of orcas swimming together, or gray whales migrating along Alaska's coastline. The Alaska cruise season, which typically runs from late spring through early fall, offers excellent opportunities for whale sightings, with the summer months being especially active.
The best whale sightings typically occur between June and August, although humpbacks, orcas, and gray whales can be seen at different times throughout the Alaska cruise season.
Sea Lions and Seals
Sea lions and harbor seals are among the easiest marine animals to spot during an Alaska cruise. Steller sea lions are often seen resting on rocky islands, navigation buoys, or coastal outcrops, while harbor seals prefer quieter waters near glaciers, where they can be found floating on chunks of ice or swimming nearby.
Sea lions are commonly spotted from May through September, while harbor seals are especially abundant during late spring and early summer, when many gather near glaciers with their pups.
Otters and Porpoises
Sea otters are another favorite among travelers thanks to their playful behavior and adorable habit of floating on their backs. They're commonly spotted in calm coastal waters, often wrapped in kelp or drifting in small groups. You may also catch a glimpse of porpoises swimming alongside the ship. Although these sightings are usually brief, they're always exciting, as the animals often surface quickly before disappearing beneath the waves.
Sea otters and porpoises are frequently seen from May to September, particularly in calm coastal waters along many popular cruise routes.

While Alaska's marine wildlife often steals the spotlight, the state's forests, mountains, and river valleys are home to just as many incredible animals. Unlike whales or seals, most land wildlife isn't typically seen from the ship. Instead, your best chances come during guided shore excursions, scenic train rides, or visits to national parks and smaller coastal communities.
Bears
Alaska is home to both black bears and brown bears (including the famous coastal grizzlies), and while sightings are never guaranteed, they're much more likely during guided excursions in areas known for salmon streams, protected forests, and national parks.
The best time to see bears is from June through September, when they're actively feeding. July and August are especially rewarding, as many bears gather near rivers to catch spawning salmon, one of Alaska's most iconic wildlife spectacles.
Bald Eagles
With their striking white heads and impressive wingspans, bald eagles are one of the easiest animals to spot during an Alaska cruise. They can often be seen soaring above the coastline, perched high in evergreen trees, or watching over harbors and fishing areas near many cruise ports.
Although bald eagles live in Alaska year-round, travelers are most likely to see them between May and September, when cruise season is in full swing and wildlife activity is at its peak.
Moose and Other Mammals
Moose are another unforgettable sight, although they're usually found farther inland rather than along the coast. Shore excursions into river valleys, forests, and national parks offer the best opportunity to spot these massive animals grazing in wetlands or wandering through wooded areas. Mountain goats are also commonly seen clinging to steep cliffs, especially in Southeast Alaska, while lucky visitors may encounter Sitka black-tailed deer, Dall sheep (on some itineraries), or even wolves from a distance.
For the best chance of seeing these alaskan animals, plan your visit between June and September. During the warmer months, animals are generally more active, vegetation is abundant, and excursion conditions are ideal for wildlife viewing.
Not every Alaska cruise follows the same route, which means wildlife sightings can vary depending on your itinerary. However, these are some of the best regions for spotting Alaska's incredible wildlife:
Can you see whales on an Alaska cruise?
Yes! Humpback whales, orcas, and gray whales are commonly seen during the Alaska cruise season, especially between May and September.
Can you see bears from the ship?
It's possible, but uncommon. Most bear sightings happen during guided shore excursions in wildlife-rich areas.
What animals are most common on Alaska cruises?
Whales, sea lions, harbor seals, sea otters, bald eagles, and porpoises are among the animals travelers see most often.
Do excursions improve wildlife viewing?
Absolutely. Guided excursions give you access to habitats where you're more likely to see bears, moose, mountain goats, and other land wildlife up close.
Are Wildlife Sightings Guaranteed on an Alaska Cruise?
No. Wildlife sightings are never guaranteed since animals roam freely in their natural habitats. However, Alaska cruises offer excellent opportunities to see whales, sea lions, seals, bald eagles, and other wildlife, especially during peak cruise season and on guided excursions.
An Alaska cruise is more than just a vacation, it's an opportunity to witness some of the planet's most incredible wildlife in one of the world's most breathtaking destinations.
With the right itinerary and a few well-chosen excursions, you'll have the chance to experience Alaska's incredible wildlife up close: whales, bears, bald eagles and sea otters, every region offers something unique. Explore Alaska Cruises to find the best options for your trip, and enjoy unforgettable wildlife viewing along the way.
