Adventure Cruises in Alaska

Vast, untouched wilderness awaits. Alaska hosts magnificent wildlife encounters and spectacular glaciers.

From ice-filled fjords to stunning rainforests, southeast Alaska is an adventurer's dream. Known as one of the most beautiful cruise areas in the world, exploring the panhandle of Alaska by small ship will deliver a holiday of a lifetime. Exploring Alaska by adventure cruise ship means you can get up close and personal with the wonders of this region.

Learn about the rich history of the area, visit Glacier Bay, the world’s largest biosphere to see whales, seals, eagles and bears and visit local tribes of the Inside Passage. The action and adventure of Alaska is never-ending, and the memories will also last a lifetime. There are many different Alaska cruise itineraries on offer, each one equally amazing.


Most Alaskan cruises will explore the ‘panhandle’ or southeast tip of Alaska. Below are some key highlights of an Alaskan small-ship cruise.

Sailing the Inside Passage - shaped by glaciers that carved it millions of years ago, the Inside Passage stretches from Puget Sound, Washington, through British Columbia, and into the Gulf of Alaska. The Inside Passage offers stunning, ever-changing scenery. Home to whales, bald eagles, sea lions, and porpoises, the Alaskan Inside Passage spans more than 500 miles and includes over 1,000 islands.

Glacier Bay National Park - Marvel at the awe-inspiring scenery as you cruise Glacier Bay, the world's largest UNESCO-protected biosphere. With a bit of luck, you’ll see brightly colored puffins, mountain goats, eagles, bears, and sea lions, all set against a stunning backdrop and the amazing sounds of nature.

Chichagof Island & Baranof Island - Just a couple of the many Alaska Islands

Tracy Arm - Prepare for breathtaking scenery as you cruise Tracy Arm. Located 45 miles south of Juneau, Tracy Arm is a narrow fjord that stretches over 30 miles. With over a quarter of the area covered in ice and home to some of Alaska’s largest glaciers, Tracy Arm offers views of stunning waterfalls and sheer rock walls over a mile high, and it's also home to hundreds of harbor seals, mountain goats, eagles, and passing whales.

Ketchikan - Known as the ‘Salmon Capital of the world,’ Ketchikan is a history-rich city. The area began with a fish saltery, then a salmon cannery, followed by copper and gold mining, and even supplying timber for the construction of WWII airplanes. Now, Ketchikan’s main industry is tourism. It's easy to see why, with museums, libraries, restaurants, and amazing wildlife sightings, including mountain goats, black bears, sea otters, humpback whales, orcas, and seals.

Sitka - Another city rich in history, Sitka, on the southern part of Baranof Island, is where the Russians lowered their flag, and the US raised its flag after the US purchased Alaska from Russia in 1867.

Best time to cruise Alaska

The best time to cruise Alaska is April through September, with the high season in June and July, mainly because of warmer weather and longer days. Early April and late September are typically the low season but offer the best chance to see the Northern Lights because of the shorter days. April and May also offer stunning scenery, with the mountain peaks still covered in snow.

Mid-April to the end of August offers the best time to see whales, particularly Orcas and humpbacks. However, whether you choose April or September, amazing wildlife sightings are a given, whether it’s mountain goats, black bears, harbor seals, sea otters, or bald eagles. Couple that with the stunning Alaska landscape, and you’re sure to have an adventure cruise to remember.

Where Alaska cruises depart from

The departure port for your Alaska cruise varies depending on the itinerary, but the most common departures are below;

Ketchikan, on Revillagigedo Island, Alaska Airlines provides daily flights from Seattle. You can also reach Ketchikan by sea via the Alaska Marine Highway System (AMHS), which has connections from the US and Canada, though the trip from Washington to Ketchikan takes about 3-4 days.

Juneau - You can get to Juneau by air or sea. Alaska Airlines offers daily flights year-round from Seattle or Anchorage, and Delta Airlines offers seasonal flights from Seattle to Juneau. The other option is the state-run ferry, the AMHS.

Petersburg - Alaska Airlines offers twice-daily flights from Washington, Seattle, and Anchorage, and you can also get to Petersburg via the AMHS.

Sitka - Alaska Airlines offers daily flights to Sitka from Seattle, Anchorage, Fairbanks, Juneau, and Ketchikan. You can also go by ferry, which takes 3-4 days.

Seattle - As a major US city, Seattle offers numerous ways to get there, from planes and trains to trams.

Check your itinerary beforehand, as different routes offer different departure/arrival options. Itineraries range from round-trip departures, such as Juneau to Juneau, to one-way trips, such as Seattle to Juneau and Sitka to Ketchikan. Your choice can depend on whether you plan to add land-based options at either end of your trip. Also worth considering is a (re)positioning cruise where the boats move from one area/country to another, offering a unique trip not normally part of regular itineraries. No matter your route, we recommend arriving at your departure location at least 1 day early to be ready for your Alaska small-ship adventure cruise.

Alaska cruise tips

Before you head off on your amazing Alaska Small Ship cruise, below is some general advice and tips to ensure your trip runs smoothly;

What to expect on an Alaskan Cruise - Alaskan cruises generally promise adventure, excitement, and the beauty of Southeast Alaska. On board, you can expect comfortable rooms, fine Alaskan cuisine, and new friends for life. Days will generally start with a hearty breakfast to set up your day, followed by hiking, whale watching, bird-watching along coastal river trails or meeting the locals. Enjoy a hot chocolate or hot toddy to warm you up throughout the day, and relax in the evening with a glass of wine at dinner. Most Alaska cruises are casual, so no need to dress up for dinner.

Plan ahead - Most Alaska cruises sell out 6-9 months in advance, so book early to avoid disappointment and guarantee your space. Mid-April to early May and late August to mid-September offer the most affordable time to go to Alaska, where you can save $400+ compared to traveling in June or July.

Arrive early - As mentioned earlier, arriving a day early helps ensure you’re on your cruise on time. Since most Alaska cruise ship departure ports require a short flight, allow time for delays.

Choosing the right trip - The best trip depends on personal preference, but all Alaskan cruises offer a great experience in this remote region. Most boats have put a lot of effort into scheduling the itineraries, so no matter which one you pick, you will have a memorable experience. Alaska itineraries are usually 7, 8, or 10 days, depending on the trip you choose. Various boat sizes are available for cruising Alaska; see our Best Small Ship Cruises in Alaska page for more information.

What to pack - The Alaskan cruise season runs from April to September, leading into and out of the summer months. Are cruises cold? The average temperatures are between 55f-65f (12-18 °C) and can drop by around 5 degrees at night, so clothing appropriate to these temperatures is required. Rainfall can be heavy in Southeast Alaska, so a waterproof jacket is also a good idea. Many Alaska cruises involve hiking, so bring a comfortable pair of hiking shoes or boots, and sunglasses are a must during the summer months, especially to protect your eyes from the glare off the water. Most Alaska cruise ships have binoculars available, but if you have your own, bring them so you don’t have to wait for a pair to free up or share.

Alaska Travel Advice: Alaska is a US state, so if you’re traveling from outside the US, you will need a valid passport with at least 6 months remaining. If you’re not a US passport holder, you will also need the correct visa to enter the US. Please check the latest visa requirements before making any travel plans.

Best way to see the Inside Passage is via small boat cruise. Large cruise ships don't come close to what the small boats can offer.

What to know about adventure cruising in Alaska

Are Alaska small-ship cruises worth it?

For the right traveler, absolutely. Small-ship Alaska cruises offer access to remote wilderness — from the calving glaciers of Glacier Bay and Tracy Arm to the totem poles of Ketchikan and the gold rush heritage of Skagway — that large ships simply can't reach. The intimate group sizes mean more wildlife time, more flexibility, and a deeper connection to the landscape. They're not for everyone: there's no casino, no Broadway show, and no poolside buffet. But if dramatic wilderness, expert naturalist guides, and unhurried exploration are what you're after, small-ship Alaska cruises are among the best travel experiences in the world.

Where do Alaska cruises leave from?

Most Alaska small-ship cruises depart from Seattle or Juneau. Seattle is a popular homeport for round-trip Inside Passage itineraries — no passport required for U.S. citizens — with excursions that visit ports like Ketchikan, Sitka, and Skagway along the way. Juneau-based sailings are common for one-way or round-trip voyages that focus on Southeast Alaska, including Tracy Arm, Glacier Bay, and the more remote waterways of the Alexander Archipelago. Some itineraries end in Sitka or Ketchikan, making them ideal for travelers who want to fly home from a different port.

How long are Alaska small-ship cruises?

Most Alaska small-ship cruises run 7 to 14 nights. A 7-night voyage covers the core highlights of the Inside Passage — typically including Juneau, Skagway, and Ketchikan, plus glacier and wildlife viewing. Longer 10–14-night itineraries allow more time in remote areas such as Tracy Arm, Glacier Bay National Park, and the outer islands of Southeast Alaska. Unlike large cruise lines, small-ship operators rarely offer sailings shorter than 7 nights.

What is the Alaska Inside Passage?

The Inside Passage is a protected network of coastal waterways stretching from Washington State through British Columbia and Southeast Alaska. Sheltered by thousands of islands and fjords, it's the scenic heart of most Alaska cruise itineraries — and the reason small ships thrive here. The calm, narrow channels allow expedition vessels to access places large ships simply can't go, from secluded coves near Sitka to the icebergs floating at the mouth of Tracy Arm. Key ports along the route include Juneau, Ketchikan, Sitka, and Skagway.

What can I see and do on an Alaska small-ship cruise?

Small-ship Alaska cruises are built around active exploration and wildlife immersion rather than onboard entertainment. Expect a mix of:

  • Glacier viewing at Glacier Bay National Park and Tracy Arm, where tidewater glaciers calve ice directly into the sea
  • Kayaking and skiff excursions through sea caves, kelp forests, and remote inlets near Sitka and Ketchikan
  • Cultural history in Skagway (Klondike Gold Rush) and Ketchikan (totem poles and Tlingit heritage)
  • Whale watching in the nutrient-rich waters around Juneau and Sitka
  • Hiking and naturalist-led walks in old-growth rainforest along the Tongass National Forest
Because small ships carry fewer passengers, excursions are unhurried, and wildlife encounters feel personal rather than crowded.

What is Glacier Bay National Park, and will my cruise visit it?

Glacier Bay National Park is a UNESCO World Heritage Site and one of the most breathtaking destinations in Alaska. Cruising into the bay brings you face-to-face with massive tidewater glaciers — including Margerie Glacier — where you can watch and hear giant chunks of ice calve into the sea. Access is limited by permit, so not every itinerary includes Glacier Bay. If it's a priority, confirm it's in your itinerary before booking. Tracy Arm, a 30-mile fjord southeast of Juneau, is a stunning alternative (or addition) featuring Sawyer Glacier, floating icebergs, and dramatic cascading waterfalls.

When do Alaska cruises run?

The Alaska cruise season runs from early May through late September. July and August are peak season — warmest, with the most daylight and the most popular, and higher fares. May, June, and September offer fewer crowds, lower prices, and excellent wildlife activity. June is particularly good for wildflowers and active bear viewing near Ketchikan and Juneau. Cruises do not operate from October through April.

Do small-ship Alaska cruises have casinos?

No. Small-ship and expedition cruise lines — such as UnCruise Adventures, Lindblad Expeditions, and American Cruise Lines — do not have casinos. The small-ship experience focuses on wildlife, nature, and cultural exploration rather than on onboard gaming or nightlife. If a casino is important to your trip, a large mainstream cruise line would be a better fit.

What wildlife can I see on an Alaska cruise?

Alaska small-ship cruises offer some of the best wildlife viewing on the planet, with naturalist guides on board to help spot and identify animals. Common sightings include:

  • Humpback and orca whales throughout the Inside Passage, especially near Juneau and Sitka
  • Brown and black bears along shorelines near Ketchikan and on excursions around Juneau
  • Bald eagles — abundant throughout Southeast Alaska, particularly in Sitka and Ketchikan
  • Sea otters, harbor seals, and Steller sea lions in the coastal waterways
  • Mountain goats on the cliffs near Tracy Arm and Glacier Bay
  • Dall's porpoises and Pacific white-sided dolphins, often seen riding the bow wake
Peak wildlife activity is in June and July, though September offers excellent whale watching as humpbacks feed before their winter migration south.

What should I pack for an Alaska small-ship cruise?

Alaska's weather is unpredictable even in summer — expect cool temperatures, frequent rain, and wind alongside occasional sunny days. Essentials include:

  • Waterproof rain jacket and pants (non-negotiable)
  • Layers: moisture-wicking base layers, a fleece mid-layer, and a warm outer layer for glacier viewing
  • Sturdy, waterproof hiking shoes or boots for shore excursions
  • Binoculars for wildlife and glacier viewing — one of the best investments you can make
  • Sunscreen and sunglasses — UV reflects strongly off the water and glaciers
  • Motion sickness remedies if you're prone to seasickness
  • Casual clothes only — small-ship Alaska cruises are entirely resort casual; leave the formal wear at home
A good daypack and a reusable water bottle round out the essentials.
