Expedition Overview
Setting foot on the 7th Continent is a polar achievement relatively few people experience in their lifetime. Even more rare is the incomparable milestone that’s achieved when a traveler crosses the iconic Antarctic Circle. Navigating south of 66°33′ S is—for most guests—the highlight of the 14-day itinerary Crossing the Circle: Southern Expedition, which rewards passengers daily with views of dramatic ice formations, humpback whales swimming alongside the ship, leopard seals diving beneath your Zodiac, penguins sliding off icebergs into crystal waters, or giant petrels soaring above the crackling sea.
Starting in 2021, this itinerary allows you to the opportunity to experience our pioneering new vessel, Ultramarine. This purpose-built vessel is designed to extend the boundaries of polar exploration and offer an unmatched Antarctic experience, including a flightseeing tour you’ll never forget and a range of adventure options more extensive than any other ship in its class.

You will begin your journey in Ushuaia, a small but bustling port town at the tip of South America. This Argentine town is an ideal gateway for you to explore the southern extent of Patagonia while preparing for your adventure ahead. Enjoy active outings in the mountains or sample handcrafted chocolate at a café in town.
As the ship sets sail in the late afternoon, you will begin your Antarctic journey, passing through the historic Beagle Channel. Named after the famed ship on which Charles Darwin traveled, the channel presents great photo opportunities of landscapes and seabirds. Eventually the channel opens up to the Southern Ocean, and onwards to Antarctica.
Your days at sea are filled with presentations led by your Expedition Team on photography, wildlife, glaciology, and history. You can also spend time on deck looking for wildlife or chatting with your shipmates over a drink at the bar.
The most common reaction upon reaching the Antarctic Continent is a sense of reverence and awe. The experience is beyond words, since few places are as untouched and enduring as Antarctica. You will begin to appreciate why this region has long captivated the attention of explorers and travelers alike. Every visit to Antarctica, we witness something new or unexpected, which means that your expedition will be unlike any other—creating a unique, personal experience.
Each day, you will take Zodiac excursions from the ship to explore local bays, channels and landing sites. With wildlife always at the forefront of our minds, you will visit penguin rookeries, scout for humpback and minke whales, and search for a number of southern seal species, including the elusive leopard seal.
Your Expedition Team will take care of you at each landing, whether you are exploring the Antarctic terrain, visiting a historic research base or consorting with penguin colonies. Chinstrap, Adélie and gentoo penguins are found here, along with five different species of seals. Zodiac and ship cruising can offer opportunities to view some of the larger local marine mammals more intimately, such as Antarctic minke and humpback whales. Each day and each excursion will present a new collection of creatures to delight you and keep your camera busy.
Your days will be busy spotting wildlife and being mesmerized by the astounding beauty of Antarctica. Listening to the crackling and crumbling of icebergs and glaciers and watching penguins waddling on the beach will become your daily entertainment, while sea kayaking, paddle excursions, or camping are optional activities available on select voyages (at an extra cost).
Crossing the Antarctic Circle is both a memorable experience and impressive achievement, as few travelers reach so far south. If conditions allow us to cross this famed latitude of 66°33 ́ S, we’ll toast the first explorers who ventured here, and you can raise a glass and take pride in knowing you’ve made it to a part of the world visited by very few people. This is raw Antarctica, home of the midnight sun, Weddell seals, and your best chances of encountering sea ice—the foundation of the Antarctic marine ecosystem.
By now, your knowledge of Adélie, chinstrap and gentoo penguins will be matched by your ability to differentiate between a leopard, crabeater and Weddell seal. Terms like ‘bergy bits’ and ‘pancake ice’ will become part of your vocabulary, yet there are still many tales to be told. As you head north, Zodiac excursions will fill your days, and your Expedition Team will continue looking out for species of seabirds, seals and whales that may have eluded you on your journey south.
As you recross the Drake, Antarctica fades away, leaving you with a collection of memories to last a lifetime. Excited conversations with your newfound friends will make the crossing fly by, regardless of weather and sea conditions. Your Expedition Team will round up its series of presentations as well, with a slideshow of the adventures you’ve shared and wildlife you’ve witnessed over the course of your voyage. Be sure to take some time to reflect on everything you’ve experienced so far.
Today, you’ll say goodbye to your Expedition Team and fellow travelers, disembarking in the morning to catch your homeward flights or continue your travels on your own.

Buenos Aires, Argentina
Look no further than the pink-toned La Casa Rosada, the opulent presidential residence, to truly appreciate that cosmopolitan Buenos Aires is proud of its art and architecture. The metropolis attracts more tourists than any other city in South America. Visitors gravitate toward the city’s artful graffiti, alfresco dining, tango dancing, and the energy of the crowds in Playa de Mayo in the heart of the 400-year-old capital.

Easter Island, Chile
Easter Island (its Polynesian name is Rapa Nui) is a remote volcanic island in Polynesia that’s known for its nearly 900 monumental statues called moai, which date from the 13th to 16th centuries. Easter Island is one of the world’s most isolated inhabited islands. Despite being part of Chile, it’s more than 3,500 kilometers from the west coast of the South American continent. Easter Island was designated a UNESCO World Heritage Site in1966.

Iguazú Falls, Argentina
Iguazú Falls is a three-kilometer stretch of massive waterfalls on the Iguazú River on the border between Argentina and Brazil. The falls, 80% of which are on the Argentine side of the river, are the largest waterfall system in the world. There are 275 individual waterfalls, some of which reach 269 feet high (82 metres). The falls actually lie within Iguazú National Park, which is a UNESCO World Heritage Site. The falls were named one of the Seven Wonders of Nature in 2011.

Santiago, Chile
It’s a city blessed by nature, yet cosmopolitan at the same time. The Chilean capital of Santiago (population 6.5 million) sits in a valley surrounded by the snow-covered peaks of the Andes and the Chilean Coast Range. Visitors have their pick of sidewalk eateries, cafes and beer halls, hillside parks, grand architecture, museums, pedestrian malls, and tony restaurants of chic neighborhoods like Providencia and Las Condes, and colorful barrios like Brasil, Lastarria and Bellavista.
Departure Dates & Cabins
Know Before You Go
For your personal safety—and to ensure you get the most enjoyment out of your polar adventure—please assess your mobility and medical requirements before booking. It is essential that guests have a high level of mobility to get in and out of Zodiac boats, and for off-ship activities such as hiking on uneven terrain. Our destinations are remote. Apart from our basic ship infirmary, it could take up to 72 hours to reach adequate medical facilities. For more details to help you assess your mobility and medical requirements before booking your voyage, please review Health & Safety.
Some of our expeditions have included transfers and these will be detailed in your Invoice and Trip Brochure.
Please note that if you have an airport transfer included in your trip, it is only available if you arrive on Day 1 of the itinerary. Please ensure your flight information on your Passenger Forms is up to date so our ground crew know when to expect you. There will be someone with a sign in Arrivals waiting for you. Please look for them and they will direct you to our group shuttle.
If you do not have included transfers, or you are arriving before Day 1, you will need to make your own way to the hotel. Most airports we travel in and out of have good taxi ranks in the Arrivals area, or you can often prebook a transfer online.
Packing is an exciting part of the trip for many of us. You will find a handy packing list towards the end of your Trip Brochure. You will have received a copy of this when you first booked. We also have two excellent videos, which you can check out here: What to Pack
Our Protection Promise allows you to make a purchase decision that will leave you worry-free in the event your plans change down the road. Please review details for each term in our Quark Expeditions Protection Promise.
