A Week on the Inside Passage: Threading Southeast Alaska by Sea
When Sarah from our BugBitten team stepped aboard a chartered ketch in Ketchikan on a grey June morning, the dock smelled of diesel, wet cedar, and something vaguely oceanic she couldn't quite name. It turned out to be low tide on a salmon estuary. The mountains above town were swallowed entirely by cloud, their peaks invisible, their lower flanks dense with Sitka spruce running straight to the waterline. The harbour was busy with float planes and commercial fishing boats. A sea otter was asleep on its back between two moorings, completely unbothered. Sarah had sailed in Patagonia, the Hebrides, and the Bay of Islands — and she said, later, that none of those trips prepared her for quite how physical Southeast Alaska felt, right from the first hour.
That sense of landscape pressing in on you — not threateningly, but insistently — is one of the defining characteristics of sailing the Inside Passage. This is not a place that sits quietly in the background while you have experiences in front of it. The terrain is assertive. The weather is assertive. The wildlife, frankly, is assertive. You are moving through something that is very much alive and only marginally interested in your presence.
What Makes This Passage Worth Your Time
The Inside Passage is, at its most basic description, a roughly 1,500-kilometre network of sheltered channels, fjords, and straits running north from Puget Sound through British Columbia and into the Alaskan panhandle, finishing around Glacier Bay. The Southeast Alaska section — Ketchikan north through Wrangell Narrows, Petersburg, Sitka, Juneau, Icy Strait, and into Glacier Bay — is widely considered the most dramatic stretch of it.
What separates it from other celebrated cruising grounds is the sheer density of spectacle per nautical mile. On a single day's motoring through Chatham Strait, you might log a brown bear fishing at the waterline, three humpbacks on a feeding run, a Steller sea lion colony bellowing from a rocky outcrop, and a bald eagle sitting on a channel marker eating something unfortunate. Then the cloud lifts briefly to reveal a glacier hanging off a peak you didn't even know was there. Then the cloud comes back. This is standard operating procedure.
The passage is also genuinely navigable by experienced sailors in a well-found vessel, which is not true of every wilderness destination of this magnitude. The channels provide meaningful protection from open Pacific swells. Anchorages — and there are hundreds of them — tend to be well-charted and reasonably protected. The summer sailing season aligns with some of the longest daylight hours on the planet. In late June, you have functional light until nearly midnight, which changes your planning calculus entirely. Night passages through complex narrows are largely unnecessary, and that matters when you are reading a channel you've never sailed before.
The Glacier Bay National Park and Preserve sits at the northern end of the Alaskan portion of the route and represents perhaps the single most remarkable sailing destination in North America. The park issues a limited number of vessel permits per season, so booking ahead is not optional — it is essential. But sailing to anchor within sight of a tidewater glacier calving icebergs into black water is the kind of experience that recalibrates your sense of scale in a lasting way.
How the Area Feels
Southeast Alaska is genuinely remote in ways that Australian east-coast sailors or Mediterranean cruisers may not be prepared for. Ketchikan, the main charter base, has a permanent population of around eight thousand people. Petersburg, north along the passage, has fewer than three thousand. Sitka, reached by crossing Sitka Sound — the one genuinely exposed stretch of the route — sits on Baranof Island and has a history as a Russian colonial capital, now expressed in an Orthodox cathedral sitting improbably among timber-frame storefronts.
These towns have frontier character not as a tourism pitch but as a practical reality. The economies run on commercial fishing, timber, and government. The people in the chandleries and the fuel docks are knowledgeable and direct. Provisioning is possible in all three major stops, though the range narrows considerably as you move north. Sarah reported that Petersburg's grocery was unexpectedly well-stocked, given its size, and the local seafood — Dungeness crab, halibut, spot prawns — was exceptional and reasonably priced when bought direct from fishing boats at the dock.
The channels themselves have a quality of containment that is hard to describe without sounding slightly dramatic. In a wide strait with cloud at two hundred metres, the water black and flat, spruce on both shores dropping sheer to the waterline, you feel enclosed in the landscape in a way that is meditative rather than claustrophobic. Radar is running. The engine is on. You are moving at six knots through something that looks like a watercolour painting and sounds like complete silence broken only by your own exhaust.
Williwaws — the sudden, violent gusts that funnel off glaciated terrain with minimal warning — are a real consideration, not a theoretical one. They can pin a boat in protected anchorages and come from directions that make no sense relative to the prevailing conditions. Local knowledge matters here, as does a good anemometer, proper ground tackle, and the willingness to put out extra rode without being asked twice.
What to Actually Do Here
Sail (or Motor-Sail) the Main Corridor
The primary activity is, obviously, moving through the passage itself. Most of the navigation is motoring or motor-sailing rather than sailing under canvas, because the channels are frequently narrow, the winds inconsistent, and the distances between waypoints require maintaining a schedule that pure sailing rarely allows. This is not a failing of the destination — it is simply the character of fjord and channel cruising. Your engine is your friend here. Make peace with that early.
Anchor in Rudyerd Bay
Misty Fjords National Monument, accessible from Ketchikan via Behm Canal, contains some of the most spectacular anchorages on the entire route. Rudyerd Bay in particular — steep granite walls sheering straight up from the water, waterfalls threading down from invisible heights — is a place where the scale of the geology is difficult to absorb. You drop the hook in calm water surrounded by walls that dwarf anything most sailors have anchored alongside, including the Norwegian fjords. Kayaking is excellent here. The silence, when the wind drops, is absolute.
Watch the Wildlife
The wildlife viewing in Southeast Alaska requires no special effort, which is partly what makes it extraordinary. Humpback whales bubble-net feeding in Icy Strait, brown bears working salmon streams at low tide, Dall's porpoises bow-riding at six knots, black-tailed deer on the foreshore at dusk — these are not curated encounters. They happen continuously, in the background, as a feature of the environment rather than an attraction within it.
Explore the Towns
Ketchikan's Creek Street — formerly the red-light district, now boutique shops and cafés perched on pilings over a salmon stream — is worth an afternoon. Sitka's Russian Orthodox cathedral and the Sitka National Historical Park, where Tlingit totem poles stand in coastal rainforest, are genuinely moving. If you're considering further land-based exploration of Alaska's protected coastal areas, the Kenai Fjords National Park on the Kenai Peninsula offers a complementary experience to the Inside Passage, though it requires additional travel west from Juneau.
When to Go (and When Not To)
June to mid-August is the window. This is the established consensus and it is correct. June and early July offer the longest daylight and the best chance of drier spells, though "drier" in Southeast Alaska is a relative term. Ketchikan averages around four metres of rain annually. Budget for rain in July without resentment — it is part of what keeps the landscape looking the way it does.
Late August sees the days shortening noticeably and the weather becoming less predictable, though it can also produce spectacular autumnal light and fewer boats in the anchorages. September is genuinely risky for passage sailing — the Pacific storm track moves south and the conditions in exposed crossings like Sitka Sound can become serious.
Spring, outside the June window, means cold, unpredictable weather, heavy snow at altitude, and limited services in many ports. Winter sailing on the Inside Passage is a specialist proposition undertaken by locals in purpose-built vessels, not a charter option for visiting sailors.
How to Get There and Nearby Stops
Getting to Ketchikan: Alaska Airlines flies direct from Seattle (Sea-Tac) to Ketchikan International Airport, which sits across the Tongass Narrows from the town itself — you take a short ferry across. From Australia, the most practical routing is Sydney or Melbourne to Los Angeles or Seattle, then north to Ketchikan. Budget two travel days from Sydney.
Charter operators: Several bareboat and skippered charter companies operate out of Ketchikan. Bareboat operators uniformly require documented cold-water offshore experience and strong references — this is non-negotiable and appropriate given the conditions. If you don't have the logbook hours, a skippered charter or a crewed expedition boat is the correct choice rather than arguing about qualifications.
Nearby stops beyond the passage: Juneau, Alaska's state capital, is accessible only by sea or air and sits roughly three-quarters of the way along the passage. The Mendenhall Glacier is a short bus ride from the harbour and provides a striking land-based counterpoint to the tidewater glaciers you'll have been watching calve from the water. For those interested in exploring broader Alaskan charter and tour options, BugBitten has a growing resource of Tours in USA that covers everything from Southeast Alaska through to the Kenai Peninsula and beyond.
The UNESCO recognition of Glacier Bay as part of the broader Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek World Heritage Site is worth understanding before you arrive — the UNESCO World Heritage Centre maintains detailed background on the ecological significance of the region and the management frameworks that govern access. Reading it before departure gives context to the permit system and the conservation rationale behind vessel traffic limits inside Glacier Bay.
The Not-So-Good Bits
Honesty first: this is not an easy or cheap sailing trip. Charter costs in Southeast Alaska are significantly higher than comparable bareboat charters in the Caribbean or Mediterranean. A competent charter vessel for two weeks will cost more than most people spend on an international flight holiday. Add provisioning, fuel (diesel consumption is high when you're motoring in calm channels all day), ferry costs, and flights from Australia, and the total budget is substantial.
The weather will test your patience. "Liquid sunshine" is a local euphemism for the kind of persistent, light rain that is too soft to wear full foulies for but too persistent to ignore. You will spend days in damp gear. The cockpit will be wet more often than not. Your books will go slightly wavy. This is fine, but it is worth knowing.
Glacier Bay permits are limited — the park issues roughly 25 private vessel permits per day during peak season — and they book out quickly. You cannot simply show up. Failing to secure a permit before departure means missing the northern culmination of the passage, which is a real disappointment given how much of the trip orients toward it. Check the UNESCO World Heritage List for context on the international significance of the area, and then go directly to the National Park Service permit system and book early.
Non-US citizens need to research CBP requirements carefully if any portion of their planned route crosses into Canadian waters. Some common routing options through the northern BC channels touch Canadian jurisdiction, which requires additional customs clearance. This is manageable but not to be discovered the day before departure.
Cell coverage disappears entirely for long stretches. A satellite communicator — SPOT, Garmin inReach, or equivalent — is not optional equipment in our view. It is basic safety kit for this environment.
Final Word from the BugBitten Team
The Inside Passage through Southeast Alaska is, without qualification, one of the most remarkable sailing routes on the planet. It is also one that asks something real of you: adequate experience, appropriate gear, thorough planning, and a genuine willingness to sit with conditions that are not always comfortable or cooperative.
What it returns in exchange is a sustained encounter with a landscape operating completely on its own terms, largely indifferent to human presence, and spectacular in ways that accumulate slowly over days rather than arriving all at once. The humpback you watch from the cockpit at ten o'clock at night, in full Arctic-summer light, will stay with you for years.
Go in June. Book your Glacier Bay permit the moment the reservation window opens. Carry offshore foulies you actually trust. And allow yourself more time than you think you need — the anchorages will keep you longer than planned, every single time.
