Soul-stirring views and incredible wildlife encounters are only the tip of the iceberg on an Antarctic Circle cruise.

Cruising from Argentina to the Antarctic Circle is an adventure like no other. As you glide through the sea aboard the impressive Ocean Endeavour, you’ll witness sights that you’ve only ever dreamed of – never-ending seascapes, remarkable icescapes, and snow-clad landscapes where Mother Nature lives in her rawest form. Not to mention the incredible wildlife that calls Antarctica home! Not only will you join a small number of travellers that can say they've crossed latitude 66°33’ S, but you’ll also visit busy penguin rookeries, see seals swimming under your Zodiac, and maybe even encounter a curious humpback as you kayak past icebergs and glaciers.

Highlights of our Antarctic Circle cruises

Two travellers raising a toast to reaching latitude 66°33’ S

Celebrate reaching 66°33’ S

Raise a toast with your crew and fellow travellers because reaching 66°33’ S (one of the five imaginary lines of latitude that maps Earth) is no small feat. You’ll join a relative handful of people  – including 18th-century explorer Captain James Cook – who can claim they've reached one of the most remote and unforgiving places on the planet. You're now surrounded by the densest concentration of wildlife in Antarctica, and this is when the magic of the journey really starts to unfold.

Three penguins jumping off icebergs in Antarctica

Visit a penguin rookery

You’ll see penguins patrolling the rocky shorelines in vast numbers from the ship, but you’ll get a much better view when you visit a penguin rookery on foot. Watch in wonder as you see groups of Chinstrap, Gentoo and Adelie penguins waddling to the water, observe families huddling together to stay warm, or maybe see a creche of adorable chicks hanging out while their parents are fishing. Your Antarctica wildlife expert will be nearby to answer your burning questions about these curious critters.

Kayakers in Antarctica

Explore on a kayak

Marvelling at the snow-covered peaks and imposing icebergs from the ship is enough to leave you speechless, but nothing beats the feeling of exploring in a kayak. Where else can you paddle around the base of glaciers, float through narrow ice-strewn corridors, or watch penguins diving underneath your kayak to hunt for their next meal? If you’re lucky, you might encounter a whale breaching to get a closer look at you, or a seal hanging out on a floating ice block.

Watch inquisitive seals

From Crabeater seals with their cream coloured fur to Southern Elephant seals with their huge trunk-like schnoz, it’s impossible to get tired of watching one of Antarctica’s most fascinating animals. There'll be plenty of opportunities to watch seals on your trip whether it's seeing them slide into the water on their bellies, diving into the icy water to hunt, or witnessing the tight bond between a mumma seal and her pup. By the end of your expedition you’ll be well clued up on your seal knowledge.

A group of travellers snowshoeing in Antarctica

Strap on a pair of snowshoes

Follow in the footsteps of early explorers as you hike the Antarctic Peninsula in a pair of snowshoes. From feeling the satisfying crunch of the snow under your boots to discovering remote alcoves and hidden valleys, snowshoeing allows you to go deeper and experience these majestic lands in a way that's not possible on a regular hike. Walking beneath snow-clad mountains, gazing at the soaring cliffs and taking in the views from hard-to-reach viewpoints is a feeling like no other.

Take a polar plunge

Will you dare to plunge into Antarctica's ice-cold waters? There's nothing quite like it to wake you up! Call us biased, but we think it's one of those things you have to do. If you don't, we're almost certain you'll spend the rest of your life wishing you'd done it – and life is too short for regrets. If your stomach flips at the thought alone, rest assured knowing you'll be attached to a safety rope for the few seconds you're in the water. There will also be a doctor on board (just in case). Your crew will welcome you back aboard with a warm, fluffy gown.

Antarctic Circle FAQs

Everyone travelling on an Intrepid trip must be fully vaccinated against COVID-19 as a condition of carriage. 

All travellers are required to produce:  

  • Proof of COVID-19 vaccination

  • If you are unable to be vaccinated for medical reasons, you may apply for an exemption. Exemptions will be assessed on a case-by-case basis. To apply, you must provide a medical certificate from a medical professional. 

In all cases, you must be fully inoculated. This means you must receive the full dosage of the COVID-19 vaccine and allow enough time for immunity to take effect. Each COVID-19 vaccine has different dosages and timeframes for inoculation, so please check the relevant medical advice associated with your vaccine.

Due to its extremely remote location (ahem, the southernmost point of Earth), there’s only one way to get to the Antarctic Circle, and that's on a polar vessel like the Ocean Endeavour. A ship like this is designed to handle the ice-strewn seas on the crossing to the Antarctic Circle. Most cruises depart from Ushuaia in Argentina and the journey to latitude 66°33’ takes roughly seven to nine days depending on your itinerary and where you stop off along the way.

The short answer is it’ll be cold! The warmest month in Antarctica is January. Even then, the maximum temperature along the coastal areas reaches a cool 5°–15°C (41–59°F), and strong westerly winds often make it feel much chillier. On the west coast, the temperatures exceed 0°C (32°F) for three to four months during the summer (December to March) and rarely fall below –10°C (–14° F) during the winter. The east coast of the Antarctic Peninsula is much colder, with mean temperatures exceeding 0°C for a month at most, while winter temperatures range from –5°C to –25°C (23 to –13°F).

The best time to visit the Antarctic Circle – or anywhere in Antarctica – is from late spring to early autumn. This is when the temperatures rise above freezing and the sea ice melts enough to allow access for polar ships. Generally, you can’t go to the Antarctic Circle in winter as the weather conditions are too precarious to travel to the region safely. There are also long periods of constant darkness on the high interior plateau.

If wildlife is one of your biggest considerations, then it really depends on the animals you’d like to see. February to March offers the best whale sightings of the year, December is the best time to see seal pups (particularly on the Falkland and South Georgia islands), and November to early December is prime time for watching the impressive courting rituals of penguins and seabirds.

Antarctica is one of the most remote and unpredictable places in the world. It's really important to pack everything you’ll need as you won’t be able to buy anything once you’re there. Some of the essentials you’ll need include:

  • warm base layers – and lots of them
  • pair of waterproof and windproof pants
  • waterproof and windproof jacket (you might be provided with this on your cruise)
  • snug-fitting beanie
  • gloves
  • bathers – for your Antarctic dip (optional, but totally worth it!), and swimming in the pool aboard the Ocean Endeavour
  • sun protection – yup, it’s sunny enough to get burnt in Antarctica!
  • moisturiser
  • camera

Intrepid is committed to making travel widely accessible, regardless of ability or disability. That’s why we do our best to help as many people see the world as possible, regardless of any physical or mental limitations they might have.

Unfortunately there is no wheelchair access on our polar vessels. Some ships have lifts but these may not access all decks on the ship. There are often stairways, and passengers need to be mobile enough to keep themselves steady and be able to get around reasonably without being assisted. We can help you to further clarify whether the trip you’re interest in is right for you. 

However, we’re always happy to talk to travellers with disabilities and see if we can help guide them towards the most suitable itinerary for their needs and where possible, make reasonable adjustments to our itineraries.
