A Local’s Guide to Whale Watching in Sitka, Alaska

Why Whale Watching in Sitka is So Special

Sitka sits on the outer coast of Baranof Island, where the mountains of the Tongass National Forest meet the Pacific Ocean. That geography creates an incredibly productive marine ecosystem. Cold, nutrient-rich waters support an abundance of fish and marine life, which in turn attract humpback whales, gray whales, sea lions, sea otters, seals, seabirds, and occasionally orcas. Much of this habitat is accessible by boat within a relatively short distance of Sitka.

That means you don't have to spend hours traveling to reach wildlife.

The wildlife is already here. (While I highly recommend taking a boat out for whale watching, there have been days that you can watch bubble netting humpback whales from the sea walk pier in downtown Sitka, or see a pod of killer whales stalking sea lions from your nook in the Sitka Public Library - rare, but surreal events for sure!)

When you leave the harbor and head into Sitka Sound, you're entering an ecosystem that changes constantly with the seasons, tides, weather, and movement of prey. That's what makes every whale watching trip different.

Humpback Whales in Sitka

Humpback whales are the stars of many Sitka whale watching trips.

They return to Southeast Alaska each year to take advantage of the region's abundant food. Around Sitka, we commonly encounter humpbacks feeding in the productive waters of Sitka Sound and along the outer coast.

One of the most incredible things about watching humpback whales is that you aren't simply watching an animal surface.

You're watching behavior.

A humpback might surface quietly beside the boat. Another may be actively feeding. You may see a powerful tail fluke disappear beneath the surface or watch a whale repeatedly surface in the same area as it works through a concentration of baitfish. Sometimes, if the conditions and feeding activity line up just right, you can witness something truly spectacular—a group of humpbacks working together to feed to bubblenet feed.

Those are the moments you don't forget.

What else you might see?

Although whales are often the main attraction, they are only one part of the Sitka Sound ecosystem.

Depending on the season and conditions, a whale watching trip can also bring encounters with:

Sea Otters

Sea otters are one of our favorite animals to encounter on the water (and one of the most common sighting on our tours). You'll often find them floating in groups, known as rafts, in protected bays and kelp beds. Watching an mamma otter groom her pup, dive for food, or simply float on its back is a quintessential Southeast Alaska experience.

Steller Sea Lions

Steller sea lions are another common sight around Sitka. These enormous marine mammals can often be found hauled out on rocky islands and reefs or actively feeding in the water. Their barking and other vocalizations can make an encounter with a sea lion colony impossible to miss.

Harbor Seals

Harbor seals can be surprisingly elusive, but keep an eye on rocky shorelines and sheltered waters. They may pop their heads above the surface or haul out on rocks to rest.

Orcas

Orcas travel throughout Southeast Alaska, and they do pass through Sitka waters. However, they are much less predictable than humpback whales. We never want to promise an orca sighting. When they do appear, it's a special bonus!

Gray Whales

Every Spring the Gray Whales conquer their annual migration from Baja to the Bering Sea, stopping in Sitka along their journey. Fun fact: Gray Whales have the longest migration of any mammal. Read our deep dive into Gray Whales in Sitka Sound.

Porpoises

You gotta be quick (or lucky), and you might catch a Dall’s porpoise or a Harbor porpoise darting through the ocean around us.

Dolphins

On the rarest of occasions, Pacific white-sided dolphins venture into Sitka Sound and the protected inside waters of Southeast Alaska. These sleek, highly social dolphins are usually found farther offshore in the North Pacific, so encountering them close to Sitka is a truly special experience.

I’ve only witnessed Pacific white-sided dolphins a handful of times in my life, but every encounter has been unforgettable. They are incredibly fast, acrobatic, and playful—often traveling in energetic groups, racing alongside the boat, leaping from the water, and riding the bow wake.

Puffins and Other Seabirds

Sitka Sound is home to an incredible diversity of seabirds, including murres, auklets, puffins, bald eagles, and many other species.

If you take a moment to look beyond the whales, you'll quickly realize how much life is moving around you.

Bears

Baranof Island has the highest density of coastal Brown Bears in the world. Later in the summer, around August and September, when salmon are returning, bears are frequently spotted feeding at the mouths of rivers along the coast.

Seeing a bear from the water is a very different experience from seeing one in a captive setting or even from land (we love the extra buffer the water provides when viewing bears). You're observing it in its natural coastal habitat, from a respectful distance.

When is the best time to go Whale Watching in Sitka?

There isn't one single “best” day to experience Sitka's wildlife.

Every season brings something different.

While we do have whales in Sitka all year long. There are peak seasons for different whale species and activities. March through October is prime whale watching season in Sitka. Here’s what to expect:

• March - April: Towards the end of March the annual Herring Spawn takes places on the shores of Sitka Sound. The spawning event itself is incredible to see, but also signals the spring awakening as marine life flocks to the area. More Bald Eagles than you can count, Stellar Sea Lions hunting in colonies, the most consistent Humpback Whale bubble net feeding, and the Gray Whale migration through Sitka. With the Gray Whale migration we may see 50+ whales at one time! Early spring is a favorite whale watching time for us - there is so much activity on the water and very few tourists in town. Read our Herring Spawn and Spring Whale Watching blog for a deep dive on Sitka Whale watching in Spring.

• May–June: Humpbacks are in Sitka Sound hungry and active. Gray whales tend to still be cruising around the neighborhood, typically in fewer numbers than earlier in the spring. Late May and early June are the quietest for humpback whales in the sound as they begin to spread out as herring (their prey) move to deeper waters. That said, we still see humpbacks or gray whales on 99% of tours during this time. Weather is generally the determining factor on whale sightings in these months.

• July–August: Whales….Whales everywhere. Humpback Whales start to congregate closer to town and in larger numbers as they chase krill and their food source becomes more abundant in Sitka Sound. This is the best window for warm weather and calm seas. It’s also when sea otter pups, seals, and a wide range of birds are most abundant.

• September: An underrated gem. Humpbacks are still feeding heavily before some of them start migrating south. And while it’s not a marine mammal, the brown bears are often spotted on the coastline feeding on the spawning salmon and watching bears from the boat is our favorite way to encounter them!

Why get out on the water in Sitka?

You can see wildlife around Sitka without ever stepping onto a boat. But there is something completely different about experiencing Southeast Alaska from the water.

From a boat, you can travel beyond the harbor and explore the islands, shorelines, kelp beds, and open waters where marine wildlife actually lives. You're not looking at Sitka from the outside.

You're in it.

The mountains rise directly from the sea. The Tongass rainforest stretches down to the shoreline. Eagles move between the trees and the water. Sea otters disappear into kelp beds. Whales surface somewhere on the horizon.

This is the Sitka we know.

And it's the Sitka we want to share with you.

What makes a local whale watching tour different?

There are plenty of ways to see whales in Alaska.

For us, being local isn't simply something we put in our company description. It's part of how we operate.

We know these waters because we've spent our lives on them. We understand that weather can change, wildlife moves constantly, and the ocean doesn't follow a schedule. That local knowledge helps us make decisions throughout the day—where to go, where to slow down, when to look, and when conditions call for a different approach.

But just as importantly, we can tell you about the place beyond what you're seeing through the binoculars.

We can talk about the fishing communities, the islands, the marine ecosystem, the history of these waters, and what it is like to actually live here.

You're not just visiting our workplace. You're visiting our home.

A small-boat approach to whale watching

At Sitka Sea Level Adventures, we believe whale watching is best experienced from a boat that allows you to feel connected to the environment around you.

Our tours are designed to keep groups relatively small while providing comfortable viewing from both inside and outside the boat.

You’ll have panoramic views from the heated cabin, along with opportunities to step outside on our open decks. And because we're operating a small boat rather than a large tour vessel, the experience feels personal.

You can ask questions.

You can talk with your captain.

You can take your time watching a whale surface.

And you aren't simply one passenger in a crowd.

What to expect on a Sitka Whale Watching Tour

We almost always see whales, sea otters, sea lions, and bald eagles. One of the most important things to understand about wildlife watching is that wildlife is wild.

We can't control where a whale surfaces or guarantee exactly what you'll see. What we can control is the experience we provide.

We'll spend time on the water looking for wildlife and paying attention to what's happening around us. We'll share our knowledge of Sitka and the animals that call these waters home, and we'll adjust our route when conditions and wildlife activity make that worthwhile.

Some days the whales are everywhere. Some days we work a little harder to find them. And trust us, the whales don’t mind a little rain!

That's the nature of wildlife.

And honestly, that's part of why we love it.

Whale watching for cruise ship visitors

If you're visiting Sitka on a cruise ship, getting out on the water is one of the best ways to experience the community beyond the downtown streets.

Our whale watching tours are designed with cruise passengers in mind, with departures conveniently located at Crescent Harbor, directly adjacent to the cruise shuttle drop-off area.

That makes it easy to transition from your ship to your boat tour without spending valuable time traveling across town.

And when your tour is over, you're right back where you started—with time to explore more of Sitka before returning to your ship.

Whale watching with kids

Sitka is an incredible place to introduce children to marine wildlife.

A whale watching trip can turn what kids learn in the classroom into something they remember for a lifetime. Seeing a humpback whale surface just a few feet away, watching a sea otter float through a kelp bed, or witnessing a sea lion feeding can spark the kind of curiosity that makes kids want to learn more. These moments give children a chance to experience the natural world firsthand—to ask questions, make connections, and discover that the animals they’ve read about are living, breathing, wild creatures right here in front of them. It’s more than a sightseeing trip; it’s a chance to create a core memory and perhaps inspire a lifelong sense of wonder about the ocean and the world around them.

Our captains are parents themselves, and are well versed in creating a safe, comfortable experience for families is important to us.

Bring your questions. Bring your curiosity. Bring your kids' enthusiasm.

We'll take care of the rest.

What should you bring?

Southeast Alaska weather can change quickly, so come prepared.

We recommend:

• Warm layers

• Waterproof outer layers (we do have an enclosed heated cabin FYI)

• Comfortable shoes with good traction

• A camera or phone

• Sunglasses

• Binoculars if you have them (we provide some as well, but bring your favorite pair if you have them!)

• Dramamine or another motion-sickness remedy if you're prone to seasickness

And don't forget your sense of adventure.

Rain is a normal part of life in Sitka. We're in a temperate rainforest, after all.

Fortunately, a little rain doesn't stop the wildlife.

Frequently Asked Questions about Whale Watching in Sitka

Are whales guaranteed on a Sitka whale watching tour?

No wildlife encounter can be guaranteed.

Humpback whales are commonly encountered during the main whale watching season, but they are wild animals and their movements are unpredictable. We'd rather be honest about that than make promises nature can't keep.

What kind of whales can I see in Sitka?

Humpback whales are the most commonly encountered whale species on our tours. Gray whales, minke whales, and orcas may also be encountered in the waters around Sitka, depending on season, location, and conditions.

Can I see more than whales?

Absolutely.

Depending on the day, you may encounter sea otters, Steller sea lions, harbor seals, bald eagles, puffins, murres, other seabirds, and potentially bears along the shoreline.

What is the best month for whale watching in Sitka?

Humpback whales are present year round - but my favorite months for whale watching are March & April (herring season and grey whale migrating with bubble netting humpback whales) or July and August (so many humpback whales, it’s fun to just sit back and enjoy - plus the bears are making more regular appearances).

However, every month offers something different, and wildlife activity varies from year to year.

Is whale watching in Sitka good for families?

Yes. Our tours welcome families and children. Seeing wildlife in its natural environment can be an exciting and memorable experience for kids and adults alike. I loved growing up in Sitka and love the experiences I share with my daughter here.

How far is the whale watching departure point from the cruise ship shuttle?

Our tours depart from Crescent Harbor, directly adjacent to the main cruise shuttle drop-off point, making the transition from your cruise transportation to your whale watching tour simple and convenient.

Experience Sitka Through a Local Lens

I've spent my entire life around these waters, and I still get excited when a whale surfaces.

That's because no two days on Sitka Sound are ever exactly the same. The weather changes. The light changes. The tides change. The birds change. The whales change (and sometimes they don’t - there are whales I’ve been seeing since I was a kid, I can tell you all about it on our tour!)

Everyday, I’m reminded how wild this place really is.

That's what we hope to share with you at Sitka Sea Level Adventures.

Not just a whale sighting.

A day on the water. A glimpse into the ecosystem. And a chance to experience Sitka the way we know it—as home.

Come explore Sitka Sound with us.

We're local. We're on the water. And we'd love to show you around.
