Inside Passage

State: Alaska (the route also passes through British Columbia and Washington). Type: coastal waterway / travel corridor rather than a single site. Alaska's portion runs roughly 500 miles north-south through the Alexander Archipelago among about 1,000 islands. Main Alaska-based access is the state-run Alaska Marine Highway ferry system plus cruise lines; Southeast Alaska port towns such as Juneau, Ketchikan, Sitka, and Skagway all sit along it.

The Inside Passage is a long, sheltered network of channels, straits, and fjords running along the Pacific coast from around Puget Sound in Washington State, through coastal British Columbia, and up into Alaska's Southeast Panhandle. Rather than a single attraction, it's best understood as the travel corridor and scenic backbone connecting most of Southeast Alaska's communities, including Ketchikan, Wrangell, Petersburg, Sitka, Juneau, Haines, and Skagway. Its islands, roughly 1,000 of them on the Alaska side, and the surrounding mountains shelter ships from the open Pacific, which is why it became a favored travel route during the Klondike Gold Rush and remains the standard route for Alaska cruises today. Wildlife viewing along the way — humpback whales, orcas, sea otters, and black or brown bears near shore — is one of the passage's biggest draws. Both large cruise ships and the state-operated Alaska Marine Highway ferries use these waters, offering very different experiences: cruise ships provide resort-style comfort, while the ferry system offers a slower, more local way to see the same coastline and reach smaller communities cruise ships skip.

Geographically, the Inside Passage spans roughly 1,000 miles of coastline, running from around Puget Sound and the Strait of Georgia in Washington and British Columbia up through Prince Rupert, BC, and into Alaska's Panhandle. The Alaska portion covers about 500 miles north-south, threading between the mainland and the Alexander Archipelago's islands. Key Alaska ports along the route include Ketchikan, Wrangell, Petersburg, Sitka, Juneau, Haines, and Skagway, with Prince Rupert, BC, and Bellingham, Washington, serving as southern gateway ports for the Alaska Marine Highway ferry system.

Weather through the Inside Passage is generally cool and often wet, typical of the broader Southeast Alaska maritime climate, with conditions that can change quickly along the route. Navigation is complicated in places by strong tides, unpredictable currents, and limited safe anchorages, part of why the protected, island-sheltered channels are preferred over open Pacific routes. Certain open-water crossings within the broader route, such as parts of Queen Charlotte Sound or stretches further north, can be rougher than the sheltered inside channels and are more likely to cause seasickness on ferries or smaller boats. Regardless of season, layered, waterproof clothing is standard advice for anyone spending time on deck.

The main travel season runs from mid-May through early September, with late May through July generally offering the best combination of milder weather, long daylight hours, and strong wildlife viewing. June and July tend to be best for humpback whale sightings, while July and August line up with salmon runs that bring bears close to shore in various spots along the route. September brings fewer crowds, better prices, and cooler, wetter conditions with a chance of fall color; May similarly offers a quieter shoulder-season option with snow still visible on the peaks.

For thousands of years before European contact, Tlingit, Haida, and other Northwest Coast peoples traveled and lived along the Inside Passage's channels, relying on its sheltered waters for fishing, trade, and travel between communities. European exploration of the route is often tied to British navigator George Vancouver, who charted much of the coastline in 1792 aboard HMS Discovery and HMS Chatham, encountering Tlingit, Haida, and other Indigenous groups along the way; his surveys became foundational to later maritime charts of the region. The passage's sheltered character made it the preferred sea route during the Klondike Gold Rush of the late 1890s, when thousands of prospectors sailed north from Seattle and San Francisco toward Skagway and the overland trails to the Yukon goldfields, a boom that helped establish towns like Skagway and grow others like Juneau and Ketchikan. In the 20th century, the state of Alaska formalized ferry service along the route as the Alaska Marine Highway System, designated a National Scenic Byway, giving remote communities without road access a lifeline for passengers, vehicles, and freight. Since the mid-20th century, the same protected waters have also made the Inside Passage one of the most popular cruise ship itineraries in the world, though the route's difficult navigation — uncertain weather, strong tides, and thousands of recorded historical shipwrecks along the Alaska section — has always demanded experienced local piloting.

Wildlife viewing is the headline activity: humpback whales and orcas are commonly spotted from ferries, cruise ships, and dedicated whale-watching boats, while shore-based sites like Anan Creek and Pack Creek offer guided bear viewing near salmon streams. Sea kayaking is popular in the calmer channels near towns like Sitka and Juneau, and small-boat operators run glacier and fjord tours branching off the main passage. Riding the Alaska Marine Highway ferry itself is an activity in its own right for many travelers, letting you watch the scenery from open-deck solariums, meet fellow travelers, and stop in small communities that big cruise ships don't visit. Fishing charters, for both halibut and salmon, operate out of many of the passage's port towns. History-minded travelers can explore Gold Rush-era sites in Skagway, Tlingit and Haida cultural sites in Sitka and Ketchikan, and totem parks scattered along the route. Birding along the shoreline and forested islands is another quieter option for slower-paced travel.

Ketchikan, often the first Alaska port for southbound Inside Passage travelers, is known for its totem poles and historic Creek Street district. Sitka combines Russian colonial history with Tlingit culture and sits more exposed to the open Pacific than most other stops. Juneau, Alaska's capital, offers glacier access via Mendenhall Glacier alongside museums and government buildings. Skagway, at the passage's northern end, preserves its Klondike Gold Rush-era downtown, much of it protected within a national historical park. Petersburg, sometimes called 'Little Norway' for its Scandinavian fishing heritage, and Wrangell, one of the region's oldest non-Native settlements, offer quieter, smaller-town stops between the bigger ports. Anan Creek and Pack Creek are the region's best-known bear-viewing sites, both requiring permits or guided access. Glacier Bay National Park, reachable by boat from the passage, adds tidewater glaciers and protected wilderness to a longer itinerary.

There's no single point of entry since the Inside Passage is a route rather than a destination, but most travelers join it either by cruise ship, typically departing from Seattle or Vancouver, or via the state-run Alaska Marine Highway ferry system, which connects Bellingham, Washington, and Prince Rupert, British Columbia, to Southeast Alaska ports including Ketchikan, Wrangell, Petersburg, Sitka, Juneau, Haines, and Skagway. Ferry reservations, especially for vehicles and cabins, are recommended well in advance and can be booked through the Alaska Marine Highway System by phone or online. Some travelers combine a partial Inside Passage ferry or cruise leg with driving the Alaska Highway to or from Canada, since only limited stretches of the passage's northern ports connect to the road system.

Not applicable in the usual sense, since the Inside Passage is a travel corridor rather than a single site with opening hours; individual attractions and ferry sailing schedules along the route each have their own timings, which should be checked separately.

There is no admission fee to the Inside Passage itself. Costs instead come from cruise fares or Alaska Marine Highway ferry tickets, which vary by route, cabin type, and vehicle, so check current fares on the ferry system's official booking page.

A full Inside Passage ferry journey between Bellingham and Skagway takes roughly three days one-way; many travelers instead do shorter multi-day segments between two or three ports, or join a week-long cruise covering part of the route.

Accommodation isn't found 'along' the Inside Passage itself but in the port towns it connects. Cruise ship cabins serve as lodging for cruise passengers moving between ports. Ferry travelers on the Alaska Marine Highway can book small multi-person cabins for overnight legs, or opt for free solarium deck space with a sleeping bag or pad for a more budget-friendly, if less private, option. In port towns like Ketchikan, Sitka, Juneau, and Skagway, hotels, inns, and bed-and-breakfasts range from historic downtown properties to modern chain hotels, with availability tightening considerably during the busy June–August cruise season.

Dining options follow the port towns along the route rather than the passage itself. Cruise ships include dining as part of the fare, while ferry passengers can buy meals in onboard cafeterias or bring their own food for longer legs. Each port town — Ketchikan, Wrangell, Petersburg, Sitka, Juneau, Haines, and Skagway — has its own local seafood-forward restaurant scene, generally strongest around fresh halibut, salmon, and crab, with smaller communities offering more limited, simpler options than larger ports like Juneau or Ketchikan.

Because the Inside Passage links so many destinations, 'nearby places' essentially means the port towns themselves: Ketchikan, Wrangell, Petersburg, Sitka, Juneau (with Mendenhall Glacier close by), Haines, and Skagway on the Alaska Marine Highway route, plus Prince Rupert, BC, and Bellingham, Washington, at the southern ends. Glacier Bay National Park and Admiralty Island's bear-viewing sites are reachable as side trips by boat or floatplane from several of these ports.

Access to the Inside Passage is inherently by water or air rather than road for most of its Alaska length. Cruise ship terminals in Seattle and Vancouver, and Alaska Marine Highway ferry terminals in Bellingham and Prince Rupert, serve as the main southern gateways. Each port town along the route also has its own regional airport for travelers wanting to fly in or out partway through a trip rather than sailing the entire distance.

Sea conditions vary a lot along the route; sections that cross more open water, rather than sheltered inside channels, can get rough enough to cause seasickness, so travelers prone to it should bring motion-sickness remedies and ask staff about the roughest legs in advance. Because rescue response times in remote stretches can be long, follow all posted safety briefings on ferries and cruise ships, and always wear provided flotation gear during kayaking or small-boat excursions. Weather can change quickly, so pack layers and waterproof gear regardless of season. If doing independent kayaking rather than a guided trip, be aware that cold-water immersion leaves very little time for self-rescue, and appropriate wetsuits or drysuits are recommended by experienced local paddlers.

Waterproof, layered clothing suited to changeable maritime weather, comfortable shoes for both boat decks and town walking, and any motion-sickness medication you know works for you are the essentials. Binoculars greatly improve wildlife spotting from the deck. If planning a multi-day ferry trip, bring a sleeping bag or pad for solarium deck camping, plus snacks, since onboard food service is limited compared to a full cruise ship.

Decide early whether you want the cruise-ship experience (comfort, fixed itinerary, larger ports) or the Alaska Marine Highway ferry experience (slower, cheaper, more flexible, and access to smaller communities cruise ships skip), since they suit different travel styles. Book ferry cabins and vehicle space well ahead for summer sailings, as popular routes and cabin classes can sell out. If you get seasick, ask about which legs of a given route cross more open water versus sheltered channels, since discussions from past travelers point to specific rougher stretches, including crossings near Queen Charlotte Sound. Consider combining a partial ferry or cruise segment with flights between ports to save time on a longer Alaska itinerary. Always check current sailing schedules directly with the ferry system or your cruise line, since Southeast Alaska routes can be affected by weather and vessel maintenance.

Dial 911 for emergencies in any port town along the route. For Alaska Marine Highway ferry reservations and customer service, the system's customer service center can be reached at 1-800-642-0066.
