Kenai Fjords Boat Tours: Which Cruise Is Worth It

Half-day bay cruise, full-day glacier run, or the deepest Northwestern Fjord trip? Here's how to pick the right Seward day cruise for your time budget, your stomach, and whether you want to watch a glacier calve.

The single most important decision is itinerary length, because it determines whether you reach a tidewater glacier at all. Only cruises of roughly 6 hours or longer round Aialik Cape to reach Holgate or Aialik Glacier; the popular 3–4.5-hour "wildlife cruises" stay inside Resurrection Bay and never reach a tidewater glacier — the number-one source of booking disappointment. For most first-time visitors, a 6-hour Kenai Fjords National Park cruise on a large, stable catamaran (Major Marine Tours or Kenai Fjords Tours) is the best-value sweet spot: a calving glacier, whales and puffins, with a heated cabin and lunch included. Choose the 7.5–8.5-hour Northwestern Fjord itinerary only if you're a keen photographer or birder who isn't prone to seasickness, and the half-day bay cruise if you're short on time, on a budget, or worried about motion sickness.

Book July/August departures well in advance, expect open-water swell once you leave the bay, and note two 2026-specific realities: there are no longer National Park Service rangers aboard the boats (interpretation is now by captains and naturalist crew), and Seward's brand-new cruise terminal opened in June 2026, increasing port-day crowding. The sections below walk through every tour type, the operators who run them, and how to match a cruise to your time budget, your stomach and your wallet. If you already know which cruise you want and just need the logistics — check-in addresses, harbor parking, and the fishing charters, water taxis and kayak boats that also leave from the docks — see every departure from the Seward harbor.

How to Choose

A quick decision guide

Three questions that point most people to the right cruise.

1

By your time budget

Have only a few hours, or want time for Exit Glacier the same day? Take the half-day Resurrection Bay cruise (~4 hours). Willing to give a full day? A Kenai Fjords National Park cruise (6–7.5 hours) reaches the tidewater glaciers. Want the longest day on the water? The Northwestern Fjord cruise (8–8.5 hours) goes deepest.

2

By seasickness tolerance

Resurrection Bay is sheltered and calm; the open-water crossings out to Aialik Bay and Northwestern Fjord can be rough. If you're prone to seasickness, the National Park Service advises a shorter Resurrection Bay trip, or motion-sickness medication taken before departure — once you feel unwell, it's too late.

3

By whether you want a calving glacier

A half-day bay cruise sees no glacier. To watch active tidewater ice calve into the sea, you need at least a 6-hour Kenai Fjords National Park cruise into Aialik Bay. For three glaciers in one trip, take the Northwestern Fjord cruise.

The Full Landscape

Every tour type Seward runs, 2026 season

Tours map onto four length tiers, plus a few specialty add-ons.

Half-day Resurrection Bay (~3–4.5 hrs)

No glacier

  • Stays entirely inside the protected bay — coastal scenery, Spire Cove sea stacks, sea otters, harbor seals, Steller sea lions, bald eagles, seabirds and, with luck, whales
  • Kenai Fjords Tours runs a 3-hour "Resurrection Bay Express" (departs 8:30 a.m.) and a 4.5-hour Resurrection Bay Tour; Major Marine runs a 4-hour Kenai Fjords Wildlife Cruise (June 12–October 11, 2026)
  • Best for families with young children, tight schedules, budgets and seasickness-prone travelers

Spring wildlife / gray-whale (~4 hrs)

The season's first cruises

  • A distinct early-season product timed to the gray-whale migration, historically running mid-March to mid-May
  • Major Marine runs a Spring Wildlife Cruise; Kenai Fjords Tours runs a 4-hour Spring Resurrection Bay Tour
  • Stays in protected water, lowest price tier

Mid-length Kenai Fjords National Park (~6 hrs)

The recommended default

  • The shortest cruise that reaches a tidewater glacier — rounds Aialik Cape into Aialik Bay to visit either Holgate or Aialik (captain's choice)
  • Major Marine's 6-hour cruise runs May 2–September 21, 2026, and is its most popular; Kenai Fjords Tours' equivalent is the "Classic Kenai Fjords National Park Tour"
  • Includes a complimentary deli lunch. Major Marine states on its official 6-hour cruise page: "On average, we see whales on 80% of our 6 Hour Kenai Fjords National Park Cruises" (an operator-reported average, not a guarantee)

Full-day Kenai Fjords (~7.5 hrs)

Both Aialik-bay glaciers

  • Reaches both Holgate and Aialik, with 20–30 minutes at each and extra wildlife time
  • Major Marine states: "On average, we see whales on 90% of our 7.5 Hour Kenai Fjords National Park Cruises." Runs May 22–September 13, 2026, departs 9:30 a.m., returns 5:00 p.m., travels ~130 miles round trip, and crosses into the open Gulf of Alaska — not recommended for those prone to motion sickness
  • Kenai Fjords Tours' comparable "Captain's Choice National Park Tour" (new for 2026) optimizes the route to the day's wildlife

Northwestern Fjord (~8–9 hrs)

The deepest, most remote, most expensive day cruise

  • Travels farthest into the park, through Harris Bay into Northwestern Fjord, to view up to three tidewater glaciers — Northwestern, plus Anchor and Ogive
  • Passes the Chiswell Islands (Steller sea lion rookery, seabird colonies) in the Alaska Maritime National Wildlife Refuge
  • Major Marine runs an 8.5-hour version on a smaller vessel, May 29–September 7, 2026 — not suitable for children under 12, not recommended for guests with limited mobility. Kenai Fjords Tours runs an 8-hour Northwestern Fjord Tour
  • Best for photographers, birders and repeat visitors who tolerate long days and open water

Dinner cruises & Fox Island

Verify before booking

  • Kenai Fjords Tours runs a 6-hour Glacier Dinner Cruise (multi-course meal glacier-side) and Fox Island combinations with a salmon/prime-rib buffet — though reviewers report the advertised menu is sometimes replaced by soup, salad and bread
  • 2026 note: at least one detailed 2026 guide reports KFT is not offering Fox Island stops on its standard national-park tours this season — confirm directly before booking a Fox Island product

Bear Glacier, the park's largest, is typically viewed only from a distance, weather permitting, on the way toward Aialik Bay — it is not approached like the tidewater glaciers.

Multi-day and lodge-based experiences: the Kenai Fjords Wilderness Lodge on Fox Island (Pursuit / Alaska Collection) offers 2- and 4-night stays in eight waterfront cabins (holds ~18 guests), including a scenic cruise, guided kayaking with Sunny Cove, gourmet meals and, on departure, a full glacier or Northwestern Fjord cruise. Kayak-cruise combos (Sunny Cove, Miller's Landing) mix a boat leg with paddling.

Aialik vs Holgate

Which glacier will you actually see?

Aialik and Holgate are both active tidewater glaciers in Aialik Bay that calve ice into the sea. Which one your cruise visits depends on the length you book and on conditions on the day.

  • A 6-hour cruise typically visits one of the two — captain's choice, based on weather and ice. Aialik is about a mile wide and 300–400 ft tall; Holgate is narrower (about half a mile) but taller, up to about 500 ft.
  • A 7.5-hour cruise visits both.
  • The longest cruises continue to Northwestern Fjord, where three glaciers meet the sea.
  • En route, weather permitting, boats may view Bear Glacier.

Good to know: if seeing the calving ice up close matters most, the 7.5-hour cruise removes the "captain's choice" uncertainty by visiting both Aialik-bay glaciers in one trip.

Big Catamaran or Small Boat?

Vessel size is a genuine tradeoff, not marketing

Large catamarans (up to 150 passengers) and small boats (6–16 passengers) both run Seward cruises, and the choice matters.

Large catamarans

Up to 150 passengers, 82.5–95 ft

  • Most stable in swell, heated indoor cabins, restrooms, snack bar or bar service
  • Fast cruising speed — can reach farther glaciers in less time
  • Wheelchair-accessible; more deck space per passenger and freedom to move around
  • Trade-off: more crowded, less intimate

Small boats

6–16 passengers

  • Proximity, flexible routing and a personal experience — better for photography
  • Support small local businesses
  • Trade-off: far less cabin comfort, more felt motion in chop (worse for seasickness), and a higher per-person price

One local outfitter notes that even large vessels are occasionally unable to enter park waters on the worst-weather days — but it happens more often to small boats.

How Rough Is the Water?

Seasickness, and how to plan around it

Resurrection Bay is sheltered and calm; the open-water crossings out to Aialik Bay and Northwestern Fjord can be rough. Per the National Park Service: if you are prone to seasickness, choose a shorter Resurrection Bay trip, or take motion-sickness medication before departure — after you feel unwell is too late.

The trade-off is straightforward. The half-day Resurrection Bay cruise keeps you in protected water the whole time, which is why it's the standard recommendation for anyone who worries about motion sickness or is travelling with young children. The full-day and Northwestern cruises are worth it for the glaciers, but they cross open water to get there, and that stretch can be bumpy — reviewers describe 8–12-foot swells on bad days once a cruise rounds Aialik Cape. If you want the glaciers and know you're sensitive, take medication ahead of time, sit low and mid-ship, stay on deck with your eyes on the horizon, and pick a calmer-weather day where your schedule allows.

Whale sightings (operator self-reported averages, not guarantees): Major Marine Tours states, for example, whales on roughly 90% of its 7.5-hour cruises and about 80% on the 6-hour. It does not publish a comparable figure for the 8.5-hour Northwestern cruise. Treat these as the operator's own reported averages rather than a promise for any given day.

Cruises "go out rain or shine," cancelling only for unsafe seas. If a park cruise is confined to Resurrection Bay by weather, Major Marine refunds a set partial amount — $30 per adult, $20 per child, less if discounted — and Kenai Fjords Tours refunds $40 per adult, $20 per child. A full cancellation refunds only the funds paid directly to the operator; packaged hotel, train or motorcoach components are typically non-refundable.

Operators

Who runs the Seward day cruises

Two big operators dominate, plus a cluster of small-boat outfitters.

Major Marine Tours

Locally/family-owned since 1990

  • 2026 season March 7–October 11
  • Large, stable catamarans with reserved indoor heated seating on every cruise, fog-free windows, multi-level viewing decks, restrooms, snack bar
  • Complimentary hearty deli lunch on cruises 6 hours and longer (turkey, roast beef or vegetarian sandwich, chips, granola bar, cookie or brownie)
  • Check-in at the Harbor 360 Hotel dock, 1412 4th Ave; free parking in a private lot

Kenai Fjords Tours

"Seward's original" cruise operator, since 1978

  • Owned by Pursuit / the Alaska Collection (CIRI-affiliated Alaska tourism); 2026 season March 12–September 27
  • Operates the largest day-cruise fleet in Southcentral Alaska: three custom 82.5-foot catamarans (M/V Aialik Voyager, M/V Orca Voyager, M/V Callisto Voyager) plus 95-foot vessels, up to 150 passengers
  • Heated cabins, large windows, walk-around decks, restrooms, snack bar; wheelchair-accessible restrooms and tables
  • $1 per ticket supports the Alaska SeaLife Center; Alaskans save 20% in 2026
  • Check-in at 1304/1412 4th Ave; free parking lot with shuttle from May 1

Northern Latitude Adventures

Small-boat specialist, six passengers

  • Based in the Seward Small Boat Harbor (1302 4th Ave, Bldg E)
  • Offers a 7.5-hour Kenai Fjords Glacier Odyssey and a 9-hour Kenai Fjords Ultimate Adventure (the 9-hour runs a short June 1–July 31, 2026 window)
  • Heated cabin, marine restroom, deli lunch and snacks included
  • The most intimate, personalized experience; best for photographers; higher price, more felt motion — not for the seasickness-prone

Saltwater Safari Company

Max 16 passengers

  • Runs 53-foot vessels (Legend and Legacy) with 360° walk-around decks
  • Full- and half-day tours, including a 4-hour bay tour

Seward Ocean Excursions

  • Small operator running set 3.5- and 6-hour itineraries

Miller's Landing & Sunny Cove

Water taxi and kayak specialists

  • Miller's Landing — family-run since ~1982 on Lowell Point; primarily water-taxi (four custom vessels, up to 22 passengers, heated cabins) and guided kayaking to Aialik Bay and Northwestern Fjord, plus partner sales of Major Marine cruises. Not a classic large-catamaran sightseeing operator
  • Sunny Cove Sea Kayaking — kayak specialist since 1996; cruise-and-kayak combos and the guided paddling for the Kenai Fjords Wilderness Lodge

Stan Stephens Cruises operates out of Valdez in Prince William Sound, not Seward/Kenai Fjords — not applicable to this itinerary. Kenai Fjords Tours' 8-hour Northwestern Fjord Tour departs at 8:30 a.m. and runs May 30–August 30, 2026; its 2026 per-person prices were not confirmed for this guide, so the indicative prices above come from Major Marine Tours — confirm current pricing with whichever operator you book.

Wildlife Expectations

What you'll likely see, by itinerary and month

Longer time on the water means better odds. The Chiswell Islands and best sea-lion viewing favor the Northwestern and full-day itineraries.

Realistic sightings: humpback whales (April–October, peak mid-May–August), orcas (year-round but peak mid-May–mid-June with the king-salmon run), gray whales (spring migration, April–May, on spring cruises only), fin and minke whales (uncommon), Dall's porpoise, Steller sea lions (Chiswell Islands rookery, reached on Northwestern and some 7.5-hour cruises), harbor seals hauled out on icebergs near tidewater glaciers, sea otters, horned and tufted puffins, common and thick-billed murres, black-legged kittiwakes, bald eagles, mountain goats on cliffs, and occasional black bears on shorelines.

MonthWhat stands out
AprilGray whales; boat-only, since the Exit Glacier road is still closed
MayHumpbacks arrive, orcas strong from mid-month, good value
JuneArguably the best overall — peak orca early, humpbacks in, longest days, full schedule
JulyBusiest, most reliable weather
AugustStrong early, thinning late
SeptemberFewer boats, moody light, shoulder close
Season & Booking Mechanics

When operators run, and how cancellation works

2026 operating seasons: Major Marine March 7–October 11; Kenai Fjords Tours March 12–September 27. Northwestern Fjord cruises run a shorter mid-season window — for example Major Marine May 29–September 7, and Northern Latitude's 9-hour trip June 1–July 31. Book July/August departures well in advance: peak dates sell out, and the new Seward cruise terminal adds port-day demand.

Cancellation and rebooking: Major Marine offers a full refund if you cancel more than two weeks out (a 30% fee applies within two weeks; OTA-listed products often allow free cancellation up to 24 hours ahead). Kenai Fjords Tours is fully refundable 4+ days prior, with one free date change and then a $15-per-person fee. Read the specific policy on your own booking channel — it varies.

Coming From Anchorage

Connecting a cruise to the train, or driving yourself

The Alaska Railroad Coastal Classic (summer) departs Anchorage about 6:45 a.m., arrives Seward about 11:20 a.m., and departs Seward 6:00 p.m. back to Anchorage (arriving about 10:15 p.m.) — roughly a 7-hour window in Seward. This pairs cleanly with a 6-hour cruise: Major Marine's 11:30 a.m. 6-hour departure is timed to the train, arriving back about 20 minutes before and departing about 30 minutes after the train, with just a 2-minute walk to the depot.

The 7.5- and 8.5-hour cruises are generally not compatible with the same-day train and are better paired with an overnight in Seward or a motorcoach package. Driving from Anchorage takes roughly 3–4 hours each way (allow 4 for Seward Highway construction or traffic) — feasible for a 6-hour cruise but a long day. Operators also sell same-day transportation packages combining a cruise with train or motorcoach transport.

2026 Reality Check

No NPS ranger is aboard the boats

The official NPS boat-tours page (updated September 12, 2025) states that Kenai Fjords National Park "does not provide boat tours or use concessionares: several local companies provide a variety of tour options," and that the park "does not have any authorized concessioners or park rangers on boat tours." By contrast, the historic 2018 NPS article "Boat Tours in Kenai Fjords National Park," last updated January 16, 2018, had said "Park Rangers provide narration on many of the cruises offered by Major Marine Tours."

The historic ranger-aboard / Fox Island ranger program lapsed around 2020 (COVID) and was not restored; 2025 federal park-staffing reductions reinforced the absence. Current narration is by experienced captains and naturalist crew. Some third-party or OTA listings and legacy operator "about" pages still advertise a ranger aboard or at Fox Island — treat those as outdated. Ranger-led interpretation continues only on land, at Exit Glacier and the visitor centers, and kids can still earn Junior Ranger status at the visitor center.

Practical Booking Advice

What to bring, and what to expect on board

What to wear & bring

  • Warm layers with a windproof/waterproof outer shell, hat and gloves — even sunny days are cold on the water
  • Sunglasses, sunscreen, a broad-brimmed rain hat, camera and binoculars

Timing & parking

Arrive one hour before departure for check-in. Parking in Seward is tight June–August; both major operators provide free lots, and Kenai Fjords Tours runs a shuttle from May 1.

Meals on board

6-hour+ cruises include a deli lunch; longer or dinner cruises add a buffet or multi-course meal; water, coffee and tea are provided; outside alcohol is prohibited; vegetarian and gluten-free options are available on request.

On the boat

Sit inside the heated cabin to warm up between sightings, but head to the rail or deck for wildlife and glaciers — the best viewing is outside. There is no park entrance fee and no separate pass needed to board.

Accessibility

Large catamarans have wheelchair-accessible heated cabins and restrooms — notify the operator in advance, as accessible seating is limited. The 8.5-hour Northwestern cruise is not recommended for guests with limited mobility.

Honest Guidance

When not to book a given cruise

SituationWhat to do instead
Severe seasickness susceptibilitySkip the Northwestern and full-day cruises; take a half-day Resurrection Bay cruise on a large catamaran, or reconsider a boat trip entirely
Very young children on long tripsThe 8.5-hour Northwestern cruise excludes under-12s; families are better served by the 3–5-hour bay cruises
Tight schedules / same-day train travelersDon't book a 7.5–8.5-hour cruise you can't finish before the 6:00 p.m. train — take the timed 6-hour departure
Bad-weather daysIf the forecast confines boats to the bay, you'll pay glacier-cruise prices for a bay cruise — consider rebooking, or accept the partial refund reality
Budget constraintsThe half-day cruise delivers wildlife and scenery at the lowest tier; you're paying a premium for glaciers on the longer trips
You want glaciers up close on foot, or aerial scaleA guided kayak trip in Aialik Bay, or a flightseeing tour over the Harding Icefield, may serve you better than a day cruise
2025–2026

What's changed lately

New Seward cruise terminal

Opened June 10, 2026

  • The $137 million Dale R. and Carol Ann Lindsey Alaska Railroad Terminal — described by Royal Caribbean Group's PR Newswire release (June 10, 2026) as "the largest and most innovative cruise terminal in Alaska," with a 748-foot floating double-pier berth and shore power — opened after a spring construction delay temporarily diverted some ships to Whittier
  • Royal Caribbean Group homeports here (Ovation of the Seas, Celebrity Summit, Silversea); per Travel And Tour World (June 2026) the port is "poised to attract over 140,000 cruise guests annually," reflecting Royal Caribbean's contractual 30-year commitment to deliver at least that many passengers a year (Trains.com) — meaning busier port days and higher demand for tours and transfers

No rangers aboard

A change from the pre-2020 norm

  • See the ranger-status section above

Record park visitation

425,369 visitors in 2025

  • Ranking Kenai Fjords the 45th most-visited U.S. national park (Dirt In My Shoes / NPS visitation data); the prior peak was 411,782 in 2021 (NPS press release, Feb 22, 2024)
  • Crowding and peak-date sellouts make advance booking more important

NOAA wildlife rules unchanged

In force since 2001

  • Per NOAA Fisheries, the Alaska humpback whale approach regulation, effective July 2, 2001, makes it "unlawful … to approach … within 100 yards (91.4 m) of a humpback whale" within 200 nautical miles of Alaska (50 CFR §216.18)
  • This limits how close any boat can approach whales — a normal part of the experience, not a shortfall of a given operator

Kenai Fjords Tours remains a Pursuit/Alaska Collection (CIRI-affiliated) operation; Major Marine remains locally/family-owned. A possible reduction or removal of Fox Island stops on KFT standard tours in 2026 is worth verifying before booking.

Our Recommendations

How to actually decide

1

Default choice for first-timers

Book a 6-hour Kenai Fjords National Park cruise on a large catamaran (Major Marine or Kenai Fjords Tours). It's the shortest trip that reaches a tidewater glacier, includes lunch, and balances cost, comfort and wildlife odds. Switch up to 7.5 hours if you specifically want two glaciers and more wildlife time and don't mind open water; switch down to a half-day bay cruise if you're short on time, budget-limited, traveling with young kids, or seasickness-prone.

2

For photographers and birders who tolerate motion

Book the Northwestern Fjord cruise (three glaciers, Chiswell Islands) or a small-boat operator like Northern Latitude Adventures for intimacy and flexibility, accepting higher cost and more motion.

3

Timing

Aim for June–July for the best combination of wildlife and reliable operations; choose late May or September for value and fewer crowds; choose an April/May spring cruise only if gray whales are your goal.

4

Book early

Reserve peak July/August dates 2–3+ months ahead — sellouts and the new cruise-terminal crowds make this essential. Verify the current Fox Island, ranger and menu details directly with the operator, since these have changed.

5

Anchorage day-trippers

Take the Coastal Classic train and the timed 6-hour 11:30 a.m. Major Marine departure; do not attempt a 7.5–8.5-hour cruise on a same-day train.

6

Thresholds that change the plan

If the morning forecast confines boats to Resurrection Bay, rebook rather than pay glacier prices for a bay cruise; if anyone in your party is strongly motion-sensitive, drop to a half-day bay cruise regardless of other goals.

FAQ

Boat-tour questions

Effectively yes. Most of the park is reachable only by water, so a day cruise from Seward's small boat harbor is the single most popular thing visitors do. Exit Glacier is the only part of the park you can reach by road; the tidewater glaciers, fjords and marine wildlife along the coast are reached only by boat. Tours run daily in summer.

A Kenai Fjords National Park cruise of 6 to 7.5 hours is the usual first-timer choice, because it reaches the tidewater glaciers in Aialik Bay for the calving-glacier experience, along with whales and Chiswell Islands wildlife. Indicative 2026 starting adult prices from Major Marine Tours run from about $239 to $269, excluding tax and harbor fees. A 6-hour cruise typically visits one of the two Aialik-bay glaciers; a 7.5-hour cruise visits both.

The National Park Service advises that if you are prone to seasickness you should choose a shorter Resurrection Bay trip, or take motion-sickness medication before departure — after you feel unwell is too late. Resurrection Bay is sheltered and calm, while the open-water crossings out to Aialik Bay and Northwestern Fjord can be rough.

Choose a half-day Resurrection Bay cruise (about 4 hours) if you have a tight schedule, are prone to seasickness, or are travelling with young children — it stays in sheltered water for wildlife and scenery but reaches no glacier. Choose a full-day Kenai Fjords National Park cruise (6 to 7.5 hours) if you want to see a calving tidewater glacier in Aialik Bay. The longest Northwestern Fjord cruises (8 to 8.5 hours) go deepest, to three glaciers.

Both are active tidewater glaciers in Aialik Bay that calve ice. A 6-hour cruise typically visits one of the two, chosen by the captain based on weather and ice, while a 7.5-hour cruise visits both. Aialik is about a mile wide and 300–400 ft tall; Holgate is narrower, about half a mile, but taller, up to about 500 ft. The longest cruises continue to Northwestern Fjord, where three glaciers meet the sea, and en route, weather permitting, boats may view Bear Glacier.

No, not in 2026. The official NPS boat-tours page states the park does not have any authorized concessioners or park rangers on boat tours. That is a change from the historic ranger-aboard program, which lapsed around 2020 and was not restored. Narration today comes from experienced captains and naturalist crew. Ranger-led interpretation continues on land, at Exit Glacier and the visitor centers.

Two operators dominate: Major Marine Tours, locally and family-owned since 1990, and Kenai Fjords Tours, owned by Pursuit/the Alaska Collection and operating since 1978 with the largest day-cruise fleet in Southcentral Alaska. Smaller outfitters including Northern Latitude Adventures, Saltwater Safari Company and Seward Ocean Excursions run 6-to-16-passenger boats for a more intimate, higher-priced experience. Miller's Landing and Sunny Cove Sea Kayaking provide water-taxi and kayak-combo access rather than classic sightseeing cruises.

Yes, for a 6-hour cruise. The Alaska Railroad Coastal Classic departs Anchorage around 6:45 a.m. and returns from Seward at 6:00 p.m., and Major Marine's 11:30 a.m. 6-hour departure is timed to that train. The 7.5- and 8.5-hour cruises are generally not compatible with a same-day train trip and are better paired with an overnight in Seward.

Ready to pick your cruise?

Match the tour to your day: a sheltered half-day bay cruise, a full-day run to a calving glacier, or the deepest trip into Northwestern Fjord. Book summer dates ahead and confirm current prices with the operator.
