Antarctica is the coldest place on Earth, and surrounds the South Pole. Tourist visits are costly, demand physical fitness, can only take place in summer (from November to February), and are largely limited to the Peninsula, Islands and Ross Sea. A couple of thousand staff live here in summer in some four dozen bases mostly in those areas; a small number stay over winter. Inland Antarctica is a desolate plateau covered by 2–3 kilometres (1.2–1.9 mi) of ice. Occasional specialist air tours go inland, for mountaineering or to reach the Pole, which has a large base. Wildlife needs access to the sea and is confined to the coasts.
About 15 million years ago, the mountain chain connecting South America to Antarctica sank under the ocean, and a new continent was born. Cold sea currents now enclosed Antarctica completely and its climate became intensely cold.
18th century explorers probed the dangerous southern oceans only to encounter a vast barrier of ice: they could hardly tell what was islands, what was a larger land mass, and what was just ice. The first sure sightings of the mainland were in 1820, by Russian, British and American ships all at about the same time. Whaling and sealing vessels began to hunt in the seas here, and explorers mapped the coast. In 1897 a Belgian expedition overwintered in Antarctica and this was the start of the "Heroic Age of Antarctic Exploration", culminating when Roald Amundsen and his crew reached the South Pole in Dec 1911. Robert Scott arrived a month later but never made it back to the coast.
Nations began setting up bases and claiming parts of the continent, while conducting scientific work. There was a particular effort at collaboration in the "International Geophysical Year" of 1957 / 58, and this led to the Antarctic Treaty of 1959. The Treaty makes the continent a scientific preserve, suspends all territorial claims, and prohibits military activity here. This Treaty has stood the test of time, and today Antarctica has no border controls, mines or quarries, missile silos, fish canneries, or any settlements beyond small collections of prefabs. Some four dozen bases are occupied year round or seasonally by a transient population, numbering a few thousand in summer and perhaps a couple of hundred in winter. Only 10% could be described as "researchers", the great majority are support and logistics staff to make the research possible. A couple of settlements style themselves "towns" and children have been born there. One base, McMurdo, even has a bus service: its route passes close to where Scott and his men perished in 1912.
Antarctica is a desert: the winds are cold, so they carry little moisture, and inland precipitation averages 50 mm (2 inch) a year, the same as the Mojave in California. And yet Antarctica is covered in ice 2-3 km thick. In a warmer climate the snowfall would run off in streams or evaporate, but here it just builds and builds. As Antarctica also has the strongest and most persistent winds of any continent, the snow (or bits of ice small enough to be carried by wind) is constantly moved around and as research stations act as artificial impediments to the free movement of air and snow, there is always the danger of those becoming "buried" by snow, requiring various techniques to avoid or at least delay this process. The bedrock beneath the ice is mostly low-lying (though there are several mountain ranges) - in fact some of the rock is actually several hundred meters below the sea - but add all that ice and most of the continent is at high altitude - the South Pole itself is 2835 m / 9301 ft above sea level. This makes a very cold climate colder still, with inland summer highs of -15°C (5°F) and winter lows below -80°C (-112°F), and thin dry air. The icecap is moving, very slowly on the plateau, faster as it descends to the coast to form glaciers and floating ice sheets which calve into county-sized icebergs.
The coast, especially the Peninsula and its nearby islands, have a slightly less harsh climate, which means their seas are not frozen in summer. This is crucial for wildlife: penguins, seabirds and seals all depend upon open water. It also means that ships can approach, bearing supplies and tourists, from Nov through Feb.
Films and TV documentaries can show you Antarctic scenery and wildlife, but don't get you into the minds of the early explorers. The following are all available to order online.
Antarctica has no immigration or border controls, but visitors to any land or sea south of 60°S need permission from an Antarctic Treaty member country. Your tour / cruise organiser will take care of this but those travelling independently should apply six months in advance.
Only five places in Antarctica can handle large, wheeled aircraft suitable for intercontinental flights in potentially hazardous conditions:
In 2021 there are no standard commercial flights to any of these airfields, but see their details above for flight package tours. Onward flights into Antarctica use various small to medium aircraft such as the Twin Otter. All the bases have access to a ski runway or at least a helipad.
Antarctica Flights make sightseeing overflights from Australia, spending 3 hours over Antarctica. Prices range from US$8000 for first-class down to $1200 for a center economy seat with no guaranteed window access.
Ship is the most common method of visiting the Antarctic, with a sailing season Nov-Feb. The vessels are usually ice-strengthened rather than icebreakers; the latter are stronger but round-bottomed, so they heave about more in the massive waves of Drake Passage. Most itineraries are to the Antarctic peninsula and nearby Antarctic islands, and they often also take in more northerly islands such as South Georgia and the Falklands.
Smaller ships (less than 100 passengers) can go where the big ships can't, getting you up closer to the nature and wildlife. Larger vessels are less prone to rough seas but have more limited landing options; both will use RIBs (powered dinghies) to get you ashore or close in among the ice floes. Big ships may have 1000+ normal capacity but be limited to 500 on Antarctic trips. IAATO rules say that at most 100 people may be ashore at any one time: that's mainly so that everyone can be swiftly plucked to safety when (not if) conditions turn dangerous. Larger ships therefore have to segment their landings, so those passengers might only get a couple of hours per day off ship. Smaller ships can get their shore parties out and back in one operation then move on to visit a second location same day. Everything is very dependent on the weather: an onshore breeze (which in these climes will be going on a gale) will send furious breakers pounding onto the landing beach. About a third of landings have to be called off.
Even on a cosy cruise ship, you need warm clothing just to stand on deck let alone get ashore: boots, hoods, glove, water repellent pants, parka, and warm underwear. Most of these items can be bought or hired in Ushuaia, but they might not have your size. So bring whatever you can from your own stock.
Many shipping companies also offer fly/cruises, so you fly one-way or round-trip from mainland Chile. These cost more but save a couple of days each way upchucking across the Drake Passage.
As of 2020, a couple of dozen companies offer trips to Antarctica: others simply act as agents, selling you on to another company and charging a mark-up for their labours. Those listed here are understood to be direct operators, though they may be hiring the vessel with crew and sharing it with other companies. Supply outstrips demand: there is a lot of last-minute availability, but trips for the eclipse of 2021 are likely to sell out early. Don't be too last-minute as even reaching the port of departure ranks as a major trip in its own right. These companies all sail from Ushuaia unless otherwise noted:
About a dozen charter sailboats, many of them members of IAATO, offer three to six-week voyages to the Antarctic Peninsula from South America. Most offer "expedition style" trips where guests are invited to help out, although usually no prior sailing experience is required. Yachts take individuals on a "by the bunk" basis and also support private expeditions such as scientific research, mountaineering, kayaking, and film-making. Compared to the more popular expedition ships, a small yacht can be more work and significantly less comfortable, but typically allows more freedom and flexibility. For the right people, this can be a far more rewarding experience.
Skis, skidoos, tractors, snowcats, helicopters and ski planes are all used to get around Antarctica, and McMurdo on Ross Island even has a bus service. Cruise ships use RIBs / zodiacs (sturdy inflatable powerboats) to ferry tourists between ship and shore; bases close to open water also use these. Bring your own fuel!
The last of the pony- and dog-sled teams retired in the 1980s. It would be neat to bring a few teams over for a "heritage" run, but given the logistics and paperwork necessary, it would probably be simpler to run an old steam locomotive here.
Antarctica is an amazing place just to look at, with its enormous calving glaciers, icebergs the size of cities, penguin colonies and towering snow-clad mountains. But even just standing there looking is going to involve exertion on your part, elaborate preparation, and a degree of risk. The distinction between seeing and doing is a fine one in many locations, and here it vanishes altogether.
There isn't much to buy in Antarctica, and most of the shops are small gift shops and souvenir shops. The largest shop is McMurdo's General Store, which would probably provide you with just about anything you will need in Antarctica.
Coming to the Antarctic marks you as a high-roller; at the very least you'll get some surprising junk-mail and pop-ups. Some cruise passengers have experienced "presentations" that were just pressure-selling of flaky investments, fine wines the quality of filling station Chardonnay, and kitsch artwork and antiques. This is not common on Antarctic cruises, whose passengers are more savvy than most, but as ever caveat emptor.
Take advice from your trip organizer on what supplies to bring. You need sufficient and some spare, but not excess which creates deadweight. Take suitable nutritional advice before extended shore trips. The main risk to the average cruise passenger is pigging out at the ship's buffet. If you're living and working on land, though, you'll find you have quite an appetite; the extra manual labor and cold temperatures result in average calorie intake nearly double of normal.
Most food at bases is frozen, dried, canned, or otherwise preserved. It's all ordered in advance and delivered just once a year around January. Fresh produce is limited, and is typically flown into bases weekly for around two months (around Nov-Dec). A large station may have a cook who can work wonderful variations on the same old pasta; small places may just have a microwave. A few bases are experimenting with indoor greenhouses where they grow fresh produce to prepare future long-term space missions or the supply of moon or mars bases. While the food produced is a very welcome break from the same-old for the crew, it's far too little to last the winter.
In the field, food must be carried or otherwise transported. It needs to be compact, energy-rich, and dry; anything liquid will freeze solid. Re-hydrating it may be a bigger challenge than heating it. Large campsites may be set up with a makeshift "kitchen" using camping equipment, or even more complete facilities including a range, oven, and even a grill; food at these will be improvised but still pretty decent. The smallest campsites and mobile teams will have to subsist on camping rations including energy bars, pemmican (a dried paste of meat, fruit, and animal fat), and highly-coveted chocolate bars.
Don't eat the wildlife: penguins, seals, bird's eggs, anything... even if it was already dead when you found it. It's illegal due to the treaty, which seeks to protect Antarctic wildlife after 200 years of over-hunting and environmental damage. Equally, don't feed them, however woebegone-cute they look, though there's no rule against leopard seals (Hydrurga leptonyx) eating you. It's very rare for them to try, what they're more likely to do is attack and puncture the pontoon floats of your RIB, mistaking their cylindrical black shape for seals.
Drinking water requires a surprising amount of forethought. In summer near the coast there may be small freshwater lakes, but they're full of bird poop plus the odd decomposing penguin. While most of the continent is covered in snow and permafrost, it must be collected and thawed, both of which take a lot of energy. Meltwater is low in minerals and tastes very flat; you may prefer yours with a dash of salt or syrup.
As in any very cold climate, never drink alcohol until you are safely in shelter. It's notorious for generating a false glow of warmth and well-being while your core body temperature ebbs away. Rules for alcohol vary by base, but it's usually available at bases' general stores and bars.
Antarctica has very long summer days, 24-hour long within the Antarctic circle. Try to maintain regular sleeping hours, as this continuous daylight disturbs the body clock. There are no hotels or lodges, and research bases won't house tourists. Most visitors sleep aboard their ship, while inland trips (eg to the Pole) have camps set up.
It is possible to obtain employment with scientific expeditions and research bases in Antarctica, but there's stiff competition for the small number of posts, only open to citizens of the relevant country. Posts are fixed-term contracts with induction and training before departure for Antarctica. Most positions are summer-only, and less than 10% of staff stay on over winter.
Staffing agencies include Antarctic Support Contract for the US, the Australian Antarctic Program for Australia, British Antarctic Survey for the UK, Antarctica NZ for New Zealand, and SANAP for South Africa. They also recruit for subantarctic sites such as South Georgia, Gough and Macquarrie.
Antarctica is an extreme environment, and accidents are unavoidable. Weigh up the risks and your own abilities before committing to a trip.
By sea is how most visitors arrive. The southern oceans are never calm, and often very rough even in summer, with hurricane-force winds and 20 m / 70 ft waves. The ship is designed to handle this so your main risks are three days of upchucking, being thrown about, falling down a stair well, or having heavy doors or items crash into you. Always have one secure handhold, and in severe weather stay in your cabin. Trips won't venture ashore in poor weather but it may deteriorate: be extremely cautious when returning in a zodiac and follow crew instructions on when to hold still and when to cross onto the landing stage. If you fall in, your survival time in these waters is less than a minute.
It's cold even on the continental fringes where most visitors go. Most cruises focus on the Antarctic Peninsula and only travel during the warmest months (late October to March). Temperatures are typically around freezing though they can drop significantly lower, so be prepared. Your standard cold-weather gear might not suffice for polar conditions: it needs to be thermally protective, wind- and water-proof, yet still allow good mobility. Seek advice from the trip organiser, and don't assume that anything will be available on ship. But conversely, the operator may prefer to issue everyone with standard kit that they know is reliable. Keeping feet warm is important on a cruise, especially when taking zodiac cruises where you won't be moving very much, taking plenty of wool socks is recommended.
It's even colder and at high altitude inland, even if you're not mountaineering: the South Pole is at 2835 m / 9301 ft.
Intense sunlight and no shelter from it: you need sunglasses and 40+ factor sunblock.
You need to be healthy and moderately fit. If you have a long-term condition such as diabetes it needs to be very well controlled: you're going to be in a stressful environment with lots of disruption to diet, activity, and day / night cycle. A medical evacuation could take days to effect and costs could approach US $1 million.
Altogether, it's hazardous yet safe, so to speak. For sure you need adequate travel / medical insurance, and an annual multi-trip policy is often the best value. This will exclude various hazardous activities, and "winter sports" are usually an extra charge. But travel insurers are generally relaxed about Antarctic tourist trips - indeed in early 2020 one insurer offered the chance to win such a trip if you took out a policy with them. So they're not seeing many claims. Antarctic travellers are healthy and switched on, they pay attention to safety briefings and are not befuddled by alcohol, herbal tobacco or hormonal bravado - altogether they're a safer group than the average ski chalet party.
Antarctica has a very fragile environment. Penguins live at the very limit of what is survivable and are especially vulnerable in the brooding / hatching season. Some habitats have extra protection and you may not enter these. Interfering with wildlife is illegal and discouraged. Unless you're a trained researcher, don't approach wildlife closely, and even when viewing from a distance try not to surround animals which might confuse or frighten them. At the same time, don't feed or help animals even if they would die without your help; if you did, it would interfere with the "survival of the fittest" and would have negative long-term consequences.
Leave no trash. Antarctic treaties require the equivalent of leave-no-trace camping. Waste disposal and sewage facilities ashore are severely limited and restricted to permanent bases; researchers in field campsites must pack everything out, including human waste. Practice good hygiene and follow any bio-security advice given, e.g. on boot washing. There's scant risk of introducing a blight upon the Antarctic apple harvest, but you don't want to be trailing penguin poop back to the ship's buffet, or catching norovirus in the washrooms.
The International Association of Antarctica Tour Operators (IAATO) is a voluntary organization of tour operators which promotes safe and environmentally responsible tourism in Antarctica. It publishes standards for its members on responsible conduct of visits.
The top-level Internet domain for Antarctic sites, .aq, is assigned to organizations that conduct work in Antarctica or signatory governments to the Antarctic Treaty. Generally, its servers are hosted elsewhere as Internet access in Antarctica is quite limited. There are no undersea cables to Antarctica; all Internet is provided by satellites, which have limited bandwidth and high latency. Bandwidth is prioritized for scientific research (and even so, for large scientific uploads it's faster to mail a thumb drive), leaving even less for personal use. All websites are slow (especially social media sites, which are throttled because they're in such high demand). Uploading selfies is okay, but video calls, streaming Netflix, and most online gaming is impossible.
Only a few sites in Antarctica have mobile phone service. Argentina's Marambia Base has 4G LTE, while the Chilean, Uruguayan, Australian, and Finnish bases have 2G GSM. Everywhere else, you would have to rely on satellite phones. Along parts of the coast, some services like Inmarsat would work, but as you get further inland, most satellites drop below the horizon. At those latitudes, Iridium satellite phones are the only ones that will work, and they should work excellently since the poles are where the orbits of every satellite overlap. Globalstar does not work (as of 2020) as its satellites can only relay to a nearby ground station, of which there are none close enough to the South Pole; even coverage near South America has been out of commission since 2015.
Post offices are few and far between, but you can send home a postcard (with a truly unique postmark) from the Chilean town of Villa Las Estrellas on King George Island, or from the former British base of Port Lockroy, or from the US or NZ post offices at McMurdo on Ross Island.
The decision to travel is your responsibility. You are also responsible for your personal safety abroad. The purpose of this Travel Advice is to provide up-to-date information to enable you to make well-informed decisions.
There are no telephone or other communication services in Antarctica. Satellite telephone and postal facilities exist only at established research stations. It would be very difficult to obtain outside assistance in the event of an emergency.
Research stations and scientific expeditions are fully dedicated to scientific research and, with rare exceptions, have no capacity to provide support of any kind to tourists or casual travellers. Independent travellers must be fully self-sufficient from the time that they leave the departure country until their return.
Other than a privately run base on the interior ice that caters to mountaineering-type expeditions, there are no tourist facilities on land. Various tourism companies can arrange excursions to the continent. The International Association of Antarctic Tour Operators (IAATO) publishes a list of its members, which is available at:

Any travel that is not part of an international scientific expedition or organized through a recognized tour operator is strongly discouraged because of its potential harmful impact on the environment and the lack of emergency facilities.
Be sure that your routine vaccines are up-to-date regardless of your travel destination.
You may be at risk for these vaccine-preventable diseases while travelling in this country. Talk to your travel health provider about which ones are right for you.
Hepatitis B is a disease of the liver spread through blood or other bodily fluids. Travellers who may be exposed (e.g., through sexual contact, medical treatment or occupational exposure) should get vaccinated.
Seasonal influenza occurs worldwide. The flu season usually runs from November to April in the northern hemisphere, between April and October in the southern hemisphere and year round in the tropics. Influenza (flu) is caused by a virus spread from person to person when they cough or sneeze or through personal contact with unwashed hands. Get the flu shot.
Measles occurs worldwide but is a common disease in developing countries, particularly in parts of Africa and Asia. Measles is a highly contagious disease. Be sure your vaccination against measles is up-to-date regardless of the travel destination.
Yellow fever is a disease caused by the bite of an infected mosquito.
Travellers get vaccinated either because it is required to enter a country or because it is recommended for their protection.
| * It is important to note that country entry requirements may not reflect your risk of yellow fever at your destination. It is recommended that you contact the nearest diplomatic or consular office of the destination(s) you will be visiting to verify any additional entry requirements. | |

Travellers to any destination in the world can develop travellers' diarrhea from consuming contaminated water or food.
Practise safe food and water precautions while travelling in Antarctica. When in doubt, remember…boil it, cook it, peel it, or leave it!
In some areas in Antarctica, certain insects may carry and spread diseases.
Travellers are advised to take precautions against bites.
There is no risk of malaria in this country.
Travellers are cautioned to avoid contact with all animals as certain infections can be shared between humans and animals.
Crowded conditions can increase your risk of certain illnesses. Remember to wash your hands often and practice proper cough and sneeze etiquette to avoid colds and the flu.
Sexually transmitted infections (STIs) and HIV are spread through blood and bodily fluids; practise safer sex.
There are no organized or stand-by search and rescue or emergency evacuation facilities in Antarctica. Costs for search and rescue (or for the evacuation of private parties) will generally be charged to the party.
Ensure that you have equipment and clothing that meet Antarctic standards.
The decision to travel is the sole responsibility of the traveller. The traveller is also responsible for his or her own personal safety.
Be prepared. Do not expect medical services to be the same as in Canada. Pack a travel health kit, especially if you will be travelling away from major city centres.
You are subject to local laws. Consult our Arrest and Detention page for more information.
The Protocol to the Antarctic Treaty on Environmental Protection (Madrid Protocol), adopted in 1991 by the Antarctic Treaty Consultative Parties, designates Antarctica as a natural reserve, devoted to peace and science. Several areas have ecological, scientific, historical or other value and are afforded special protection. It is forbidden to bring any non-native species into Antarctica. This includes poultry, pet dogs, pet cats and household plants. It is also prohibited to take or harmfully interfere with Antarctic wildlife except in accordance with a permit issued by a national authority.
The Madrid Protocol came into force in 1998 and was ratified by 30 countries. Under the Madrid Protocol, parties are required to regulate the activities of expeditions organized in or proceeding from their territory to the Antarctic, as well as the activities of their vessels, aircraft and Antarctic stations.
Canada ratified the Madrid Protocol in December 2003, and developed the Antarctic Environmental Protection Act and its supporting regulation to implement the Protocol in Canada. In so doing, the Canadian government oversees the activities of its citizens in the Antarctic, and provides the means to address potential future environmental risks in the Antarctic.
Antarctica is the coldest, driest, highest (on average) and windiest continent, with 99 percent of its area covered by a permanent ice sheet. Weather conditions are severe and can vary.
