CRUISES
Antarctica cruises: the Drake Passage, the season and the landing rules
Ships for the Antarctic Peninsula leave from Ushuaia, Punta Arenas or Montevideo, and from Ushuaia the Drake Passage takes about two days each way; air-cruises fly over it from southern Chile. The ship's passenger count then decides how long you get on land.
Most Antarctica cruises from South America head for the same stretch of coast: the South Shetland Islands and the Antarctic Peninsula, the arm of the continent that reaches up toward South America. The first decision is how you cross the Drake Passage, by sea from Ushuaia, Argentina, or by air from southern Chile. The second is a number, the ship's passenger count, because it decides whether you set foot on the continent at all.
Sailing the Drake Passage from Ushuaia
IAATO, the tour operators' association, names Ushuaia in Argentina, Punta Arenas in Chile and Montevideo in Uruguay as the gateway ports for the peninsula.
Lindblad Expeditions puts the crossing at two days at each end of the voyage, four days in all. That is a big slice of a typical trip: of the 150 Antarctica sailings on CruiseDirect's page on November 7, 2026, 83 ran 10 to 14 nights. IAATO says all its member operators run educational programs, so the sea days fill with lectures. Lindblad itself warns of turbulent water and pitches its fly-over trips partly at people prone to seasickness. Longer voyages add the Falkland Islands and South Georgia.
Flying over it from Chile
An air-cruise replaces the crossing with a charter flight of about two hours to King George Island in the South Shetlands, where a Zodiac takes you out to the ship. Two operators show the range:
- Antarctica21 flies from Punta Arenas. Its Classic Antarctica Air-Cruise lasts 8 days and 7 nights, runs from late November to early March, and includes two hotel nights in Punta Arenas plus loaned waterproof boots.
- Lindblad Expeditions flies from Puerto Natales on 74-seat BAe 146 jets run by DAP Antarctica Airways, landing at Chile's Frei base. The charter flights are billed on top of the cruise. Its 10-day Sail and Fly trip crosses the Drake by sea on the way down and flies back.
The catch is weather. Low cloud, fog and strong wind at King George Island hold the planes on the ground, in both directions. Antarctica21 publishes its record: of 274 flights from 2003 to March 2023, 213 left on the scheduled day and 16 left a day early. Another 32 went a day late, 10 went two days late, and three waited longer. If it hasn't flown you south by 2 p.m. on Day 4, the trip is called off and the cruise fare refunded in full. A delay on the way home just means more days on the ship, with no refund. Lindblad tells guests not to book an onward flight from Puerto Natales before 1 p.m. on the last day.
The planes also cap your luggage. Antarctica21 allows 25 kg (55 lb) per person including hand luggage, with no single bag over 20 kg (44 lb), and stores anything extra in Punta Arenas. Lindblad allows one 19.9 kg (44 lb) checked bag, a 5 kg carry-on and a small personal item, and leaves overweight bags behind. Neither sells extra allowance.
So fly if you can spare only about a week, the length of Antarctica21's classic trip, or if the thought of the Drake keeps you up at night. Sail if a two-day weather wait in Chile would wreck your plans.
When to go
Ships only go in the southern summer. Lindblad's season guide puts the high season at early November to late March, with 20-plus hours of daylight and daytime highs between 24°F and 40°F. By April, the guide says, the northern coast is down to six hours of daylight and lows near 15°F, and the season is over.
| When | What it tends to be like |
|---|---|
| Early season (November) | Deep snow and heavy ice. Penguins are courting and nesting. Crowds are smaller and fares are usually lower than at the peak. |
| Mid-season (December and January) | The longest daylight and the mildest weather. Chicks begin to appear. This is the busiest and usually the most expensive period. |
| Late season (February and March) | Whale sightings tend to increase and penguin chicks are growing up. Less ice means some farther sites are easier to reach. |
The same guide fills in the wildlife. Early in the season, as the ice breaks up, penguins come ashore to court at their rookeries. December brings the first chicks. In February the pack ice is at its lowest of the year, which lets ships push farther south, and in March the baleen whales are still feeding before they swim north.
Why the ship's size decides your time ashore
Landings follow the Antarctic Treaty's General Guidelines for Visitors, which IAATO publishes. Four rules do most of the work:
- Only one ship (any vessel carrying more than 12 passengers) may be at a landing site at a time.
- Ships with more than 500 passengers may not land anyone.
- No more than 100 passengers may be ashore from a ship at once, and fewer where a site's own rules say so.
- There must be at least one guide for every 20 passengers on land.
IAATO sorts ships into the same bands: 13 to 200 passengers, 201 to 500, and over 500, which it lists as cruise-only. The arithmetic follows from the 100-person cap. On a ship of 100 or fewer, everyone goes ashore together. A 200-passenger ship lands in two groups. A 480-passenger ship needs five, so each guest gets a fifth of the ship's time at that site. If standing on the continent is the point, look up the passenger count before you look at cabins.
| Ship type | What to expect |
|---|---|
| Small expedition ship | Landings and Zodiac outings on most days, naturalists on board and talks between stops. Comfort ranges from simple to luxurious. |
| Mid-size expedition ship | More cabins and facilities, and landings in shifts so everyone gets a turn. |
| Large cruise ship | Scenic cruising along the Peninsula, with no landings. Check this before you book if stepping ashore matters to you. |
| Fly-cruise | A shorter trip that starts after a flight to King George Island, with the same landing rules. |
When we checked on November 7, 2026, CruiseDirect's page listed Antarctica sailings from seven lines: Atlas Ocean Voyages, HX Expeditions, Seabourn, Silversea, Viking Expeditions, Holland America Line and Princess Cruises. The last two had two sailings each. Princess is sending the 3,560-guest Majestic Princess this season on a 17-day Antarctica & South America cruise with four days in the Antarctic region. At that size it can't land anyone, so those days are scenic cruising. You'll see the ice from the deck, but you won't stand on it.
On shore in the 2026-27 season
Bird flu has changed the landing routine. IAATO says highly pathogenic avian influenza was confirmed in the Antarctic Treaty Area in February 2024, and its protocols for 2026-27 add two rules at wildlife sites: don't sit or lie down, and don't put bags or gear on the ground or snow. The general guidelines already ask you to stay at least 5 meters from wildlife and 15 to 25 meters from fur seals, and to take nothing home, feathers and pebbles included.
Biosecurity starts before you leave. IAATO's Don't Pack a Pest sheet asks you to clean boots, pockets and trouser cuffs at home, and it discourages any clothing or gear with Velcro, where seeds hide. On board, you scrub and disinfect your boots at a wash station before and after every landing. Leave the drone at home too: IAATO's FAQ says its members don't allow recreational drones in Antarctica's coastal areas.
What the fare leaves out
Antarctica21's air-cruise price covers the flight, two hotel nights and loaned boots, plus the IAATO passenger fee. Lindblad bills its charter flights on top. When two sailings look close on price, check these items for each:
| Item | What to check |
|---|---|
| Flights | Fares to Buenos Aires, plus the domestic flight to Ushuaia or Punta Arenas. Arrive a day or two early. |
| Hotel nights | Some operators include a night before departure. Others do not. |
| Clothing and gear | Some lines provide a waterproof expedition jacket and boots on loan. Ask what is included. |
| Optional activities | Kayaking, camping and similar extras are often charged separately and can sell out. |
| Insurance | Medical care and evacuation from a remote region are costly. Read our guide to cruise insurance and check the cover for polar voyages. |
| Gratuities and onboard spending | Check whether tips, drinks and Wi-Fi are in the fare. |
Antarctica21 requires medical cover that includes air evacuation from Antarctica. Its ship has a doctor and a small infirmary for minor problems, and it says serious emergencies are flown to hospitals in South America. Our travel insurance guide explains evacuation cover. Before you buy, confirm the policy doesn't exclude polar or remote regions.
Packing and papers
Antarctica21 gives the average summer temperature on the peninsula as about 0°C (32°F), colder in the wind, and suggests the layers you'd wear skiing under a windproof, waterproof jacket and trousers. It adds that most landings are wet, so knee-high waterproof boots matter more than hiking shoes. Lindblad gives its fly-over guests a parka but rents out boots and waterproof pants, so ask your line what it supplies before you shop. Bring dark sunglasses for the glare off the ice. For everything that isn't polar gear, use our cruise packing list.
You don't need a visa for Antarctica itself. You need whatever Argentina or Chile asks of your passport for the days before and after.
Antarctica cruise questions
When is the Antarctica cruise season?
Early November to late March, the southern summer, according to Lindblad Expeditions. Antarctica21's air-cruises run from late November to early March. By April the northern coast is down to about six hours of daylight.
How long does it take to cross the Drake Passage?
About two days each way from Ushuaia, so four days of a round trip, according to Lindblad Expeditions.
Can you go ashore from a big cruise ship?
Not from one carrying more than 500 passengers. The Antarctic Treaty's visitor guidelines bar those ships from landing anyone, and no ship may have more than 100 people ashore at once.
Is there a way to skip the Drake Passage?
Yes. Air-cruises fly about two hours from Punta Arenas (Antarctica21) or Puerto Natales (Lindblad) to King George Island and board the ship there. Delays come with it: Antarctica21 says 45 of its 274 flights through March 2023 left one to four days late.
Do I need special insurance for Antarctica?
Antarctica21 makes it a condition: you need medical cover that includes air evacuation from Antarctica, because serious cases are flown to hospitals in South America. Whatever line you sail with, check that your policy doesn't exclude polar regions.
