Alaska’s Inside Passage: Cruise Routes, Ports & What to See
Most cruise travelers visiting Southeast Alaska stop in several ports along the Inside Passage, and one of the questions we hear all the time is: ‘What should we do while we’re in port?’ After years of welcoming visitors to Skagway and exploring these ports ourselves, I’ve put together my personal picks for making the most of your entire trip. Of course, I think Skagway is the highlight — but here are some ideas for your whole journey. - Nicole
What Is the Alaska Inside Passage?
The Alaska Inside Passage is a sheltered coastal route that threads roughly a thousand miles between islands and mountains, running from Puget Sound north through coastal British Columbia and into Southeast Alaska rather than crossing open ocean. It is the reason this region can be cruised comfortably at all: ships travel inside a maze of forested islands, protected channels, and narrow straits instead of exposed Pacific water.
For a cruise passenger, that geography changes the whole trip. The water is calmer than an open-ocean crossing, there is scenery on both sides of the ship for most of the day, and the hops between ports are short enough that you wake up somewhere new without losing a day at sea. Conditions vary, but the Inside Passage is generally the gentlest way to see this part of North America by boat.
Within that corridor sits the greater Tongass National Forest, the largest temperate rainforest in the country, along with tidewater glaciers, salmon rivers, humpback whales and orcas, bald eagles, brown and black bears, and the Gold Rush history that still shapes towns like Skagway. Push a little further inland from the coast and you reach the passes into Canada and the Yukon, which is why some of the most iconic tours here are not on the water at all.
Nearly every Alaska cruise itinerary uses some version of this route, which is why the same handful of ports repeats across cruise lines. Whether you sail round trip from Seattle or Vancouver, or one way across the Gulf of Alaska, the Inside Passage is the through line, and the ports below are the ones you are most likely to see.
Which Ports Does an Alaska Inside Passage Cruise Visit?
Most Inside Passage itineraries call at some combination of Juneau, Ketchikan, Skagway, Sitka, and Icy Strait Point, with scenic cruising through Glacier Bay, Tracy Arm, or Endicott Arm in between. The mix depends on your cruise line and sailing length rather than on anything you choose, so it is worth checking your itinerary and then planning each port day around how long your ship is actually alongside.
Juneau is Alaska’s capital and the busiest excursion port in the region, and it sits at the edge of the Juneau Icefield. It is the base for helicopter glacier landings, Mendenhall Glacier, and some of the most reliable whale watching in Southeast Alaska. Ship calls here typically run somewhere between seven and thirteen hours, which is usually enough for a glacier trip and a wildlife trip in the same day if the timing lines up.
Ketchikan is the first Alaska port on most northbound sailings and the cultural heart of the region, with one of the world’s largest collections of standing totem poles, the boardwalks of Creek Street, and floatplane access to Misty Fjords. It is also a serious fishing and rainforest town. Calls are often shorter here, roughly seven to ten hours, so it rewards picking one thing and doing it properly.
Skagway is the Gold Rush town, and it gets the longest port days in the network, frequently thirteen to fifteen hours. That extra time is what makes the bigger trips possible: the White Pass railway, the drive over the pass into the Yukon, glacier flightseeing, and dog sledding. It is also the smallest and most walkable of the main ports, which is why getting just beyond the dock pays off so well here.
Sitka faces the open Pacific rather than a protected channel, and it feels different from the rest: quieter, wilder, and layered with Tlingit and Russian history. Ships are usually in port around eight hours, sometimes tendering rather than docking, which is worth accounting for when you choose a tour. Sea kayaking, coastal wildlife cruises, and the Alaska Raptor Center are the signature experiences.
Icy Strait Point, at Hoonah, is the newest of the major stops and the most purpose-built: a restored cannery, a Native-owned operation, and some of the best bear and whale viewing anywhere in the state. Ships generally spend about nine hours here. Because almost everything is reached from one small point, it is an easy port to plan even if it is your first Alaska cruise.
Recommended Tours
Skagway Highlights E-Bike Tour
This little Gold Rush town is surrounded by mountains, waterfalls, and coastal wilderness — and just minutes from the cruise dock, you’ll find quiet roads and historic sites most visitors never see. Our e-bike tour is one of the easiest and most fun ways to explore it all. We’ll take you past Centennial Park, the Gold Rush Cemetery, Lower Reid Falls, and up to the City Overlook for views you won’t forget. It’s the real Skagway, not just the cruise dock.
Whale Watching & Mendenhall Glacier Tour
Juneau is surrounded by glaciers and rainforest, and it’s one of the best places on the Inside Passage for wildlife and glacier viewing. This tour combines two of the region’s most iconic experiences in one outing — you’ll spot whales, sea lions, and eagles on the water before visiting one of Alaska’s most famous glaciers. It’s the kind of day that makes people fall in love with Alaska.
Saxman Native Village & Lumberjack Show
Ketchikan is known for its rich Native culture, colorful waterfront history, and deep ties to Alaska’s fishing industry. This tour takes you to Saxman Native Village to see one of the largest collections of standing totem poles in Alaska and learn about the traditions of the Tlingit people. Then you’ll head to the Great Alaskan Lumberjack Show for a high-energy competition that’s pure Alaska fun. It’s culture and entertainment in one perfect afternoon.
Sitka Sound Kayak Adventure
Sitka feels different from the other Inside Passage ports — quieter, wilder, and surrounded by forested islands and open ocean. This kayak tour takes you paddling through calm waters where sea otters, bald eagles, and sometimes even whales are commonly spotted. It’s a peaceful and unforgettable way to experience Alaska’s wildlife and scenery right from the water.
When Is the Best Time to Cruise the Alaska Inside Passage?
The Inside Passage cruise season runs roughly from May through September, and the month you choose changes what you get rather than whether the trip is worth taking. Every part of the season has something the others do not, so the honest answer depends on whether you are optimizing for weather, wildlife, daylight, or fares.
May and early June are the quietest and often the driest weeks of the season, with snow still sitting on the peaks and lower fares before the summer rush. Tour availability is good, and the towns feel less crowded, though water temperatures and some high-country conditions are still on the cold side.
Late June through July brings the longest daylight and the warmest weather of the year, and it is also the busiest and most expensive stretch. If you want to be outside until ten at night, this is the window, but it is the period where popular tours sell out earliest and where booking ahead matters most.
August is the strongest month for wildlife. The salmon runs are in full swing, which concentrates bears at the streams and keeps whale activity high, including the bubble-net feeding Southeast Alaska is known for. It is also noticeably wetter, so plan on rain being part of the experience rather than an interruption to it.
September brings fall colour, the lowest fares of the season, and the shortest days, with some operators winding down toward the end of the month. What does not change in any month is the underlying fact that this is a rainforest, so rain gear is never wasted here, and the people who enjoy Alaska most are the ones who stop waiting for perfect weather and go anyway.
A Final Tip From Nicole
Cruising through Southeast Alaska is one of the most beautiful trips you can take. Every port has something unique to offer, but one piece of advice I give every guest is this: get a little beyond the main cruise dock if you can.
Whether it’s riding bikes outside Skagway, kayaking in Sitka, or watching whales in Juneau, those experiences are the ones travelers remember long after their cruise ends.
And when you’re in Skagway, we’ll see you on the bikes.
Questions About Alaska Inside Passage
Where Is the Alaska Inside Passage?
The Inside Passage is the protected coastal corridor running from Puget Sound in Washington, north along the British Columbia coast, and into Southeast Alaska. The Alaska portion covers the panhandle, including Ketchikan, Sitka, Juneau, Skagway, and Icy Strait Point.
It is a route rather than a single place, which is why the region is usually described by its ports rather than its borders.
How Long Is an Alaska Inside Passage Cruise?
Seven nights is the most common length, sailing round trip from Seattle or Vancouver and calling at three or four Alaska ports with a day of scenic glacier cruising.
Longer options exist. One-way Gulf of Alaska sailings between Vancouver and Whittier usually run eight days, and some repositioning and extended itineraries run two weeks or more, adding ports and glacier days.
What Is the Best Month to Cruise the Inside Passage?
June and July give you the warmest weather and the most daylight, which is why they are the most popular and the most expensive months of the season.
If wildlife matters more to you than weather, August is the better choice for bears and whales. If fares and quiet matter most, look at May or September.
How Much Time Do You Get in Each Port?
It varies by port and by ship. Skagway tends to get the longest days, often thirteen to fifteen hours. Juneau commonly runs seven to thirteen hours, Icy Strait Point around nine, Sitka around eight, and Ketchikan roughly seven to ten.
Your itinerary is the authority here, and it is the first thing to check before booking anything, because it determines which tours can realistically fit.
Do You Need to Book Inside Passage Shore Tours in Advance?
For the popular trips, yes. Helicopter glacier landings, the White Pass railway, and bear viewing have limited daily capacity and are the first to sell out, especially in July.
Booking once your ship’s schedule is set is the safest approach. Every tour booked through us is timed to your ship and carries our guarantee that you will be back aboard before it sails.
What Should You Pack for the Alaska Inside Passage?
Layers and a genuinely waterproof outer shell matter more than a heavy coat, because you will move between a warm ship, an open boat, and a rainforest trail in the same afternoon. Broken-in waterproof shoes, a warm hat, and binoculars are the things guests most often say they were glad to have.
