An Arctic or Antarctic expedition cruise is a small-ship voyage built around Zodiac landings rather than ports of call, carrying anywhere from a dozen to a few hundred passengers. Your choice comes down to the wildlife you want to see, how much time you’ll spend ashore, and how the ship, season and route decide what you get to experience.
Arctic cruise or Antarctic cruise: how to choose
An Arctic cruise and an Antarctic cruise have almost nothing in common beyond the small-ship format. Go north and you’re after polar bears, walrus and the northern lights, reached through Norway or Greenland. Go south and it’s penguins, whales and icebergs the size of office blocks, reached through South America.
Svalbard, part of Norway, has more polar bears along its marginal ice zone than anywhere else in the Arctic, and since the bears don’t hibernate, you’ve got a shot at seeing one across the whole season. The season itself runs roughly late May to late September, but late June to late July is the easy window for a first trip: daylight round the clock, bird cliffs loud enough to hear from the Zodiac, enough ice retreat to push further north, and shores clear enough of snow to land on.
Antarctic expedition cruises have been growing fast. More than 120,000 people visited in a recent season, and roughly a third of them were on cruise-only ships too big to put anyone ashore, according to the International Association of Antarctica Tour Operators (IAATO).
Arctic numbers across Svalbard, Greenland, Arctic Canada and Franz Josef Land have climbed the same way, from around 50,000 a year to nearly 80,000 within a decade, according to the Association of Arctic Expedition Cruise Operators (AECO).
Big ships that cruise by, and small ships that land you ashore
Some ships sail all the way to Antarctica without putting a single passenger ashore. IAATO bans any vessel carrying more than 500 passengers from landing at all, so everyone on board sees the continent from the deck or through a window, full stop.
Celebrity Equinox is one of them: a large mainstream ship with well over 2,500 guests, sailing round trip from Buenos Aires on itineraries built around two days of scenic cruising past Elephant Island, Paradise Bay and the Antarctic Peninsula. No landings, no Zodiacs. It’s a fine way to see the scenery from a sun lounger, but a bad match if you were picturing a trip to a penguin colony.
Ship size also decides how much time you spend ashore once you’re on a proper expedition vessel. Carry 200 passengers or fewer and everyone can land in one or two Zodiac rotations, which often means four or five hours ashore in a day.
Carry 200 to 500 and groups have to rotate in shifts, which can cut your actual time on land by 40 to 60 percent compared with a smaller ship doing the same landing.
Ice class and ship type: why it decides where you can go
Ice class decides which routes a ship can physically get to, not just how smooth the ride is. Ratings run from PC1 at the top down to PC7, though almost no passenger ship holds a PC1 certificate. Category A ships (PC1 to PC5) are built for at least medium first-year ice; Category B ships (PC6 to PC7) are built for thinner first-year ice only.
PC1 through PC5 can sail year-round. PC6 and PC7 are seasonal ratings, good for the warmer months only, with no certification for winter at all. A PC5 ship can generally push further north or south, and earlier or later in the season, than a PC6 ship can, which matters if you’re booking a shoulder-season Arctic sailing in May or September, or an Antarctic trip outside the main window.
The Northwest Passage makes the difference obvious. The minimum class usually quoted is PC6 to PC7, with PC4 to PC5 recommended if you want a smoother transit; our guide to planning a Northwest Passage cruise covers what the route involves. For a wider look at which operators run which type of ship, see the guide to leading polar expedition cruise ship operators.
Getting to the Arctic and Antarctic from the UK
Getting to a polar expedition cruise from the UK means at least one extra flight and usually a night somewhere en route, because there’s no direct flight from Britain to either gateway region. Every Svalbard voyage starts in Longyearbyen, the world’s northernmost commercial airport, and you get there by flying to mainland Norway first.
That connection is the main headache in booking an Arctic trip. You go via Oslo (about three hours onward) or Tromsø (about ninety minutes onward).
Most operators build a buffer night into the itinerary, either in Oslo or in Longyearbyen itself, so a missed connection doesn’t cost you the ship. A seasonal budget route from London Stansted to Longyearbyen has also been used by people making their own way there.
Add two or three days on top of the sailing itself to cover UK flights and that extra night; a 7 to 10 day Svalbard voyage or an 11 to 15 day full circumnavigation both need this buffer built in. The Longyearbyen departure port guide covers what to expect when you land.
Antarctica works differently: voyages leave from Ushuaia in Argentina, or by fly-cruise through Punta Arenas in Chile, both of which mean a long-haul flight to South America plus a connection, covered in the Ushuaia departure port guide. With that much time spent in transit either way, a decent pair of compression socks for the long flights earns its spot in your case.
Wildlife by region: polar bears, penguins and the northern lights
Wildlife is the main reason most people pick one pole over the other. Svalbard gives you the best odds of seeing a polar bear anywhere in the Arctic. May to August is generally the prime hunting season, while sea ice still lets small ships push north, though one operator reckons August and September are the best months specifically.
The northern lights are another Svalbard draw. Your best window runs from late September through to mid-March, once the polar night gets dark enough for the sky to put on a proper show; September itself, right as summer tips into autumn, is also worth having on your radar.
Antarctica’s season runs on the southern summer, when the Drake Passage and the landing sites open up. You’ll see different penguin species, whales and seals across a Peninsula sailing, but which ones turn up where comes down to the landing site more than the month, so check an operator’s itinerary rather than assume every stop has every species.
The polar cruise wildlife guide goes into more detail on what to expect at each type of landing.
The North Pole: a different kind of expedition entirely
Reaching the true North Pole has nothing to do with a normal Arctic cruise. You’d need to charter a specific class of nuclear-powered icebreaker, one that can crush through ice up to three metres thick, on a voyage that’s historically run around two weeks and cost many times more than a standard Arctic or Antarctic sailing.
These trips have been running since the late 1980s, usually carrying little more than a hundred passengers at a time.
The operator running these voyages has suspended its summer polar programme in Russian territorial waters following the war in Ukraine, which pauses the charter arrangement that made North Pole landings possible in the first place. It hopes to start again when conditions allow, but has redesigned its Arctic programme in the meantime to sail round trip from Svalbard instead, circumnavigating the archipelago or visiting Northeast Greenland National Park without going anywhere near Russian waters.
Who can go: permits, IAATO rules and landing limits
Anyone can travel to Antarctica or the Arctic. There’s no personal permit to sort out; you just book with an operator that belongs to IAATO (Antarctica) or AECO (the Arctic), and they handle the environmental paperwork for you.
IAATO sorts member ships by size: C1 vessels carry 13 to 200 passengers, C2 vessels carry 201 to 500, and YA vessels carry 12 or fewer, and all of these can land within the rules. CR vessels, anything over 500 passengers, are cruise-only.
Across every landing category, the group ashore at any one site is capped at 100 passengers, guides work to a 1:20 ratio, everyone keeps at least 5 metres from wildlife, and no food goes ashore except water. Some sites are tighter still: Prion Island in South Georgia, a Wandering Albatross breeding site, allows only 20 guests ashore at a time.
Biosecurity gets taken just as seriously, with boots and gear cleaned before and between every landing so seeds, soil or disease don’t hitch a ride between sites. The polar cruise responsible travel guide covers these rules in more depth.
Realistic costs: budgeting an Arctic or Antarctic expedition cruise
Polar expedition cruise costs swing wildly depending on the operator, the ship and what’s included. The market splits roughly into entry-level lines running older, simpler ships at the cheaper end, and mid-premium lines with newer vessels, more onboard activities and sometimes even a helicopter, which push the scale up a fair bit.
Whatever fare you’re quoted, build in more on top. Once you add flights to the embarkation port, cold-weather gear, gratuities and insurance, the realistic all-in cost usually comes out around a third higher than the cruise fare on its own. Gratuities are charged as a daily per-person rate on top of that fare, before you even get to bar tabs, wifi packages and the gift shop.
Stepping off a Zodiac into a stiff Antarctic or Arctic wind is proper cold, so a proper waterproof outer jacket earns its place in your hand luggage even if the ship hands you boots. For a fuller breakdown of where the money goes on a typical voyage, see the budgeting a polar expedition cruise guide.
Common mistakes when booking an Arctic or Antarctic expedition cruise
- Booking a large mainstream ship and expecting Zodiac landings, when anything over 500 passengers is barred from landing in Antarctic waters at all.
- Booking outside the ice-access window for your route, then finding out the ship can’t push as far north or south as you’d hoped.
- Judging the cost by the headline fare alone, rather than the roughly one-third uplift once flights, gear and gratuities go on top.
- Assuming any expedition ship can have a crack at the Northwest Passage or the North Pole, when both need a specific ice class or a chartered nuclear icebreaker most lines simply don’t run.
- Underestimating how long the trip really takes once UK flights and a pre-cruise overnight in Oslo, Tromsø or Longyearbyen are added in.
If you’re not sure what else to pack beyond your outer layers, the polar cruise preparation guide is a better starting point than a standard cruise packing list.
Arctic and Antarctic expedition cruise FAQs
Can anyone travel to the North Pole?
Anyone can travel to the North Pole in principle, since it sits in international waters with no country’s territory to stop you, but getting there depends entirely on chartering a nuclear-powered icebreaker, and that trip is currently suspended by its operator.
Is the Northwest Passage included in a standard Arctic expedition cruise?
The Northwest Passage is not included in a standard Arctic expedition cruise. It’s a dedicated itinerary that needs a ship with a higher ice class rating, typically PC6 or above, and you book it separately from a regular Svalbard voyage.
Can you fly over the Drake Passage instead of sailing it to Antarctica?
Flying over the Drake Passage is possible on fly-cruise itineraries departing from Punta Arenas, Chile, saving you roughly two days of sailing each way compared with crossing it by ship, though it usually costs more than a standard sailing.
What’s the difference between a C1 and a C2 expedition ship?
A C1 ship carries 13 to 200 passengers and a C2 ship carries 201 to 500, under IAATO’s classification. Both can land passengers in Antarctica, but the larger C2 ships generally give you less time ashore per person, since the Zodiacs have to run in shifts.
