Viking’s Submarine-Equipped Polar Expedition Ship
Viking Octantis launched in 2022 as the near-sister ship to Viking Polaris, and together they form Viking’s purpose-built polar expedition fleet. Both ships share the same 378-guest capacity, 189 all-balcony staterooms, PC6 polar class, Science Lab, and Viking’s signature no-casino, curiosity-first culture. The critical difference: Viking Octantis carries two custom-built submarines.
The submarines are designed for passenger use and allow guests to descend beneath the polar surface in complete safety. In Antarctica, this means experiencing the underwater world of the Southern Ocean: bioluminescent life, the submerged portions of icebergs, and the marine ecosystem beneath the ice edge that most Antarctic travelers never see. It’s a genuinely differentiated experience that makes Octantis the more compelling choice of the two when both are available on the same itinerary.
The broader Viking expedition model applies equally to both ships: no children under 18, intellectually curated programming, citizen science through the Science Lab, and a guest demographic of experienced global travelers. For those who have sailed Viking’s river or ocean products and now want Antarctica, Octantis combines the familiar Viking atmosphere with expedition access that surpasses many pure expedition vessels on the specific dimension of what happens beneath the surface.

What makes Viking Octantis the ship

Multi-Venue Dining
Multiple venues, wine/beer included with dinner
Viking’s polar dining program operates across multiple venues with a no-reservation, open-seating format that emphasizes informal gathering over scheduled formality. The World Café provides a buffet-style setting for casual meals, while the main dining room offers a more structured menu program each evening. Specialty venues are available without surcharge for all guests. The beverage program follows Viking’s ocean cruise model: wine and beer are included with dinner, with premium beverages available at additional cost. Viking does not operate a casino or entertainment venues that compete with the expedition experience for guests’ evening attention.

Observation Deck
Open-air wildlife watching and iceberg viewing deck
Viking’s open observation deck is where passengers spend most daylight hours in Antarctic and Arctic waters — binoculars out, cold air in the face, nothing between you and whatever the polar environment decides to do. Purpose-designed for wildlife watching with broad sight lines and standing room for impromptu congregations when something surfaces off the bow.

Custom Viking Submarines
Included on qualifying itineraries, two passenger subs
Viking Octantis is equipped with two custom-built Viking submarines — purpose-designed for passenger use in polar waters and capable of descending to depths that reveal the underwater world of the Southern or Arctic Ocean. In Antarctica, submarine excursions allow guests to observe the submerged portions of icebergs (which are typically 90% underwater), bioluminescent marine life, and the seafloor ecosystem beneath the expedition landing sites. The submarines operate from the Hangar and hold multiple passengers per dive. The submarine program is included in the base fare on qualifying itineraries and is coordinated by the expedition team based on conditions. It is the most unique onboard feature currently available on any polar expedition ship.

Onboard Science Lab
Active research partnerships, guest participation
Viking’s onboard Science Lab is a genuine working research facility — not a display space or exhibit — that partners with universities and scientific institutions to run active research projects on every polar voyage. Guests participate as citizen scientists in data collection, species identification, and environmental monitoring programs. Lab specialists lead structured sessions that give non-scientists meaningful participation in real research. The Science Lab reflects Viking’s intellectual brand positioning and is the feature most frequently cited by returning Viking polar guests as having meaningfully changed their understanding of the destination.

Zodiac Exploration
Small-group shore landings and wildlife excursions
Daily Zodiac landings in most conditions bring guests to Antarctic shore sites, wildlife colonies, and ice formations that the main ship can’t reach directly. Viking’s expedition team coordinates all shore programming across the ship’s 378-guest capacity — no small operational feat, and one they’ve refined into an efficient rhythm.

All-Balcony Staterooms
Private outdoor balcony in every stateroom category
Unlike most expedition ships, where balconies are reserved for premium categories, Viking Polaris and Octantis give every stateroom a private balcony — including entry-level cabins. In Antarctica, this means watching the Drake swell or a whale breach from your own outdoor space, regardless of which category you booked. It’s a rare commitment in the expedition segment.

The Hangar
Sea-level climate-controlled launch facility
The Hangar is Viking’s sea-level expedition launch facility — a climate-controlled space that opens to the water at the ship’s stern, providing direct access for Zodiac and kayak deployments without guests needing to navigate multiple deck levels in expedition gear. The Hangar also houses the ship’s fleet of kayaks, standup paddleboards, and small vessels. The design concept prioritizes efficiency and comfort in cold conditions, and the result is one of the most well-organized shore excursion departure systems in the current expedition fleet.
Cabins + suites
Where you'll sleep.

Owner’s Suite (OS)
114 m² (1,223 sq ft) / Forward wraparound Nordic Balcony / Sleeps 2–4
The Owner’s Suite on Viking Polaris and Octantis is the largest accommodation on either ship — 114 m² positioned at the bow with a forward-facing wraparound Nordic Balcony that provides the most dramatic polar views of any suite in the Viking fleet. The layout encompasses a master bedroom, full living room, formal dining space, wet bar, pantry, and a spa bathroom with dual sinks, walk-in shower, and soaking tub. The forward position means you are watching Antarctica or the Arctic approach from the ship’s point, a vantage point that no other suite can offer. Accommodates up to four guests, making it the natural choice for families booking the top of the market on a Viking polar voyage.

Explorer Suite (ES)
Approx 95 m² (1,023 sq ft) / Large Nordic Balcony / Sleeps 2
The Explorer Suite on Viking Polaris and Octantis is a two-room flagship suite with an expansive private Nordic Balcony that spans the full width of the suite, a master bedroom, separate living room, full dining area, wet bar, and a spa bathroom with soaking tub and walk-in rain shower. Butler service, personalized excursion scheduling, and priority boarding are all standard. At this category, Viking’s commitment to quiet, purposeful design reaches its peak — there are no art auctions, no casinos, no entertainment trying to fill the room. Just the suite, the Science Lab, and whatever is outside the balcony doors.

Nordic Penthouse (NP)
Approx 45 m² (488 sq ft) / Nordic Balcony / Sleeps 2
The Nordic Penthouse is a fully realized suite on Viking Polaris and Octantis — a separate bedroom and living room configuration with a significantly enlarged Nordic Balcony, soaking tub alongside the walk-in shower, and elevated butler service. At this category the Scandinavian design philosophy reaches its fullest expression short of the flagship suites: materials, lighting, and layout all feel calibrated rather than accumulated. The suite’s separation of sleeping and living spaces makes it particularly well suited for the longer Arctic itineraries where the quality of the onboard environment becomes a meaningful part of the overall experience.

Nordic Junior Suite (NS)
Approx 37 m² (400 sq ft) / Nordic Balcony / Sleeps 2
The Nordic Junior Suite is where the Viking polar stateroom crosses into suite territory — a more spacious layout with a defined sitting area separate from the sleeping space, and a Nordic Balcony that feels genuinely useful at this footprint. The suite maintains Viking’s signature Scandinavian design language: warm woods, clean lines, and natural materials selected with a kind of restrained intentionality that makes the room feel considered rather than decorated. Butler service and priority shore excursion boarding apply at this category.

Deluxe Nordic Balcony (DN)
24 m² (257 sq ft) / Nordic Balcony / Sleeps 2
The Deluxe Nordic Balcony Stateroom expands on the entry category with additional floor space, a more generous layout, and the same Nordic Balcony that distinguishes the Viking polar fleet. The room’s added square footage is most appreciated during at-sea Drake Passage crossings and longer Arctic legs where time inside the stateroom accumulates. All of Viking’s standard inclusions apply: king bed convertible to twins, heated bathroom floors, and the full expedition and Science Lab program.

Nordic Balcony (N)
21 m² (222 sq ft) / Nordic Balcony / Sleeps 2
The Nordic Balcony Stateroom is the entry category on Viking Polaris and Octantis — and even here, Viking does something no other expedition ship does: every stateroom, including the entry level, comes with a Nordic Balcony. It’s a floor-to-ceiling glass-enclosed sunroom that converts to an open-air viewing platform with a stabilizing shelf for binoculars or a camera. At 222 sq ft with a king bed (convertible to twins), heated bathroom floors, and the full Viking Science Lab and expedition program included at every category, the Nordic Balcony Stateroom sets the floor higher than most expedition ships’ midpoint.
