Polar tourism is self-regulated to an unusual degree. In Antarctica, IAATO members limit landings to 100 people ashore at a site at once with a 1:20 guide ratio, and ships carrying more than 500 passengers may not land at all. In the Arctic, AECO plays the equivalent role alongside national law, Svalbard now bars ships over 200 passengers from its protected areas and restricts landings to 43 approved sites. Following the rules is not optional and your expedition team will enforce them.

There is an unavoidable tension in polar travel: the regions most vulnerable to a warming climate are reached by burning fuel to get there. Nobody serious about this pretends otherwise.

What the industry argues in response is that regulated tourism creates a constituency of advocates and funds research it could not otherwise afford. Whether that trade is worth it is a judgement you are entitled to make for yourself. What follows is what the rules actually are, and what your choices genuinely affect.

Antarctica: the Treaty and IAATO

Antarctica is governed by the Antarctic Treaty System, which sets the continent aside for peace and science, and by its Environmental Protocol, which designates Antarctica a natural reserve.

Tourism is managed in practice by the International Association of Antarctica Tour Operators (IAATO), a self-regulating industry body whose members carry the overwhelming majority of visitors. The core operational rules:

  • No more than 100 passengers ashore at any one site at a time
  • A guide-to-visitor ratio of about 1:20
  • Ships carrying more than 500 passengers may not land passengers at all
  • One ship per site at a time, coordinated through a shared scheduling system
  • Site-specific visitor guidelines for the busiest landing sites

Scale, for context: IAATO recorded 118,491 visitors in the 2024-25 season, after 122,072 the year before. About 98% of voyages operate in the Peninsula region during the austral summer, which concentrates pressure on a small number of sites, Neko Harbour logged 220 landing calls in 2024-25, Whalers Bay 194, Portal Point 184 and Danco Island 173.

That concentration is the real environmental question in Antarctic tourism, more than the raw visitor total.

The Arctic: AECO and national law

The Arctic has sovereign states, permanent residents and Indigenous communities, so tourism sits under national law with AECO, the Association of Arctic Expedition Cruise Operators, providing the industry framework on top.

Svalbard’s regulations, tightened in recent years, are the strictest:

  • Ships carrying more than 200 passengers are barred from the protected areas, which cover about 65% of Svalbard’s land and 86% of its territorial waters
  • Landings are restricted to 43 approved sites within those areas
  • Polar bears must be given a minimum of 500 metres from 1 March to 30 June and 300 metres from 1 July to 28 February
  • Vessels must withdraw if a bear changes its behaviour at all, standing, halting feeding, or continuing to swim rather than hauling out
  • Walrus require a minimum of 300 metres at sea

AECO also publishes guidelines on community visits, cultural sites and biosecurity that apply across Greenland, Canada and the Russian Arctic.

Biosecurity

The single most effective thing an individual passenger does.

Before the first landing you will be asked to vacuum and inspect every item of outer clothing, bag and pocket for seeds, soil and organic material. Velcro and boot treads are the usual offenders. This is tedious and it matters, introduced species are among the most serious long-term threats to polar ecosystems.

Between landings, boots are washed and disinfected on returning to the ship, and often on leaving it. Some sites require additional decontamination to prevent transferring avian influenza or plant material between colonies.

Nothing is left behind and nothing is taken. No rocks, no bones, no feathers. In Antarctica this is a Treaty obligation, not a courtesy.

Behaviour ashore

  • Keep the required distance and let animals set the terms, if wildlife approaches you, stand still and let it pass
  • Stay on the routes the guides mark, which avoid nesting sites and fragile moss beds. Moss damaged by a bootprint may take decades to recover
  • No food ashore, no smoking, no drones
  • Keep noise down, especially near colonies and haul-outs
  • At cultural and historic sites, touch nothing, Arctic trapper huts and Antarctic historic huts are protected

Emissions and what the industry is doing

The honest position: a polar voyage is a high-carbon holiday, and the long-haul flights to the gateway usually outweigh the ship.

What is changing is real but partial. Newer expedition vessels use hybrid diesel-electric propulsion and battery packs to cut fuel burn and to run silently near wildlife. Heavy fuel oil is banned in Antarctic waters, and its Arctic ban is phasing in. Some operators have moved to LNG or invested in shore power where ports support it. Most sell carbon offsets, whose real-world value is contested and which are not a substitute for flying less.

If reducing impact matters to you, the choices that actually move the needle are: fly less to get there where a routing allows, go once and go longer rather than repeatedly, and choose operators who publish their emissions and research commitments rather than those who market a vague green story.

Citizen science

Most expedition operators now run genuine data-collection programmes, and passenger participation is real rather than decorative:

  • Happywhale, photographing whale flukes for individual identification, feeding a global database that tracks migration
  • Seabird and marine mammal surveys logged from the bridge on standardised transects
  • Cloud observations for NASA’s GLOBE programme, matched against satellite passes
  • Phytoplankton and water sampling, including Secchi disc readings and salinity
  • Penguin colony counts contributing to long-term population monitoring

These voyages reach places research vessels rarely visit, and the resulting datasets are used. If this interests you, ask what a ship actually runs before booking, the range between operators is wide.

Research station visits

Many Antarctic itineraries include a station call, and they are worth understanding properly.

Stations host visitors at their own discretion and around their own work, a planned visit is cancelled without notice if the science requires it. Common calls include Port Lockroy, the restored British base and post office on Goudier Island run by the UK Antarctic Heritage Trust, along with Ukrainian, Argentine, Chilean and other national bases.

Buying from a station shop or post office generally funds heritage conservation or the station itself. Behave as a guest in a workplace: follow the escort, don’t wander, and accept that the people there have jobs to do.

Common questions

Is Antarctic tourism regulated by law or by the industry?

Both. The Antarctic Treaty System is the legal framework; IAATO provides the operational rules its members follow.

How many people visit Antarctica?

118,491 in the 2024-25 season, down slightly from 122,072 the previous year.

Why are big ships not allowed to land?

Antarctic rules bar landings from ships carrying more than 500 passengers, and cap shore parties at 100 at a time, to limit site pressure. Large ships can still cruise past without landing.

What is the minimum distance from a polar bear?

In Svalbard, 500 metres from 1 March to 30 June and 300 metres for the rest of the year, and further if the bear reacts to you.

Does the biosecurity check really matter?

Yes. Introduced seeds and pathogens are among the most serious threats to these ecosystems, and passengers are the main vector.

Do carbon offsets make a polar cruise sustainable?

No. They are a partial mitigation at best. Flying less and travelling less often are the meaningful levers.
