Venturing below the Antarctic Circle is about more than just earning bragging rights. It is the chance to enter a different world more rarely seen, it feels more isolated and colder than further north, with great swathes of pack ice and dreamlike icebergs. Thread through pack ice and narrow channels where scenes of ice-clad mountains, feeding whales and lively penguin colonies become lasting memories. Polar Expeditions prioritize the experience over the itinerary, adapting daily to offer the optimal experience per weather, wildlife, tides and ice conditions.

On select departures, skip sailing the Drake Passage and instead fly to and/or from Antarctica. For expeditioners who prefer to focus their energy on adventures in Antarctica, flying over the Drake Passage in both directions is the ideal way to reach the white continent. In the safe hands of experienced pilots, your pulse will quicken as you glimpse the first icebergs in the Southern Ocean, where your vessel awaits, ready to take you on an exhilarating adventure.

Additional alternative itineraries include the 15-day Antarctic Feast and the 17-day Antarctic Southern Realms. The Antarctic Feast features unique inclusions such as an elevated menu by a guest chef, a Christmas feast, onboard cooking demonstrations and included premium alcohol throughout the voyage. The 17-day itinerary explores the farthest, beyond the Antarctic Circle, and also adds time in the Weddell Sea with its tabular icebergs, abundant fossils and large Adelie penguin colonies.

Adventure- and conservation-minded expedition ships Greg MortimerSylvia Earle and Douglas Mawson serve as floating basecamps in Antarctica. These 132- to 154-guest-average small ships feature modern technology, state-of-the-art efficiency and nimble design for active off-ship excursions.

If you are already in Ushuaia, we ask you to make your way to your hotel. Check-in is from 3:00pm. This afternoon, visit the hospitality desk in the hotel lobby, between 3:00pm and 7:00pm, to collect your luggage tags and confirm if you wish to join the Lake Escondido pre-embarkation tour tomorrow. The team will confirm details regarding your embarkation day, answer any questions and provide you with information on where to dine or purchase last-minute items.

Expeditioners arriving after 7:00pm will find a welcome pack waiting for them at check-in. We ask you to visit the hospitality desk tomorrow between 8:00am–10:00am.

MEALS N/a

This morning, enjoy breakfast and check-out. Please ensure your cabin luggage is fitted with cabin tags clearly labelled with your name and cabin number. Take your cabin luggage to hotel reception, prior to, or at check-out. Your luggage will be stored and transferred directly to the port for clearance, to be placed in your cabin ahead of your arrival on board. Please keep any valuables or personal items with you throughout the day.

Those wishing to join the Lake Escondido tour today, please meet in the hotel lobby at 8:45am. This tour offers an unforgettable panoramic drive through big valleys of glacial origin, evergreen and deciduous forests, waterfalls and rivers, in the vastness of the Andes Mountain Range. You will leave Ushuaia city to the northeast of Tierra del Fuego, driving through peat bog valleys to reach Garibaldi Pass, only accessible by a winding road that will take you to a panoramic point. From here you will have amazing panoramic views of Lake Escondido and, if weather conditions allow, of Fagnano Lake. You will start your descent towards the northeast to reach Fagnano Lake’s shore where you will visit a local ranch. After appreciating the landscape, you will have the chance to enjoy the typical Fuegian Lamb barbecue. Enjoy some free time there before returning to Ushuaia for ship embarkation.

Alternatively, enjoy your day at leisure and meet at your hotel lobby or from the meeting point at the parking lot near the pier (details will be given by your ground staff at the hotel), to be transferred to the pier for embarkation.

Once on board, you’ll have time to settle into your cabin before important mandatory briefings. As the ship pulls away from port, gather on the deck to commence your adventure with spectacular views over Ushuaia and Tierra del Fuego.

This evening, get to know your fellow expeditioners and friendly expedition team and crew at a welcome dinner to celebrate the start of a thrilling adventure to Antarctica.

ACCOMMODATIONS Greg Mortimer, Sylvia Earle
MEALS Breakfast, Dinner

As you commence the Drake Passage crossing, make the most of your time getting comfortable with the motions of the sea. Your expedition team prepares you for your first landing with important wildlife guidelines and biosecurity procedures, and they start their lecture program to help you learn more about Antarctica’s history, wildlife and environment.

Wildlife experiences begin as you enjoy watching and photographing the many seabirds, including majestic albatrosses and giant petrels, following your vessel. On sea days, you can enjoy the facilities on board the vessel including the gym, sauna and Jacuzzis, or relax in one of the observation lounges.

Nearing the South Shetland Islands and the tip of the Antarctic Peninsula on the afternoon of Day Four, the excitement is palpable with everyone converging on one of the observation decks watching for your first iceberg. The ocean takes on a whole new perspective once you are below the Antarctic Convergence and are surrounded by the surreal presence of floating ice sculptures. The memory of your first big iceberg sighting is likely to remain with you for a lifetime. Time and weather permitting, attempt your first landing in Antarctica by late afternoon.

ACCOMMODATIONS Greg Mortimer, Sylvia Earle
MEALS Breakfast, Lunch, Dinner

It’s almost impossible to describe the feeling of arriving in Antarctica. Spotting your first iceberg and taking a deep breath of some of the most fresh, crisp air on earth is an experience that will stay with you forever.

Once you arrive, the western side of the Antarctic Peninsula and the South Shetland Islands are yours to explore, and you have a host of choices available. Because you are so far south, you will experience approximately 18-24 hours of daylight and the days can be as busy as you wish.

Your experienced expedition team, who have made countless journeys to this area, will use their expertise to design your voyage from day to day, choosing the best options based on the prevailing weather, ice conditions and wildlife opportunities.

You will want to dress warmly before joining Zodiac cruises along spectacular ice cliffs or among grounded icebergs, keeping watch for whales, seals and porpoising penguins. Zodiacs will also transport you from the ship to land, where you can visit penguin rookeries, discover historic huts and explore some favorite spots along the peninsula.

While ashore, aim to stretch your legs, wandering along pebbly beaches or perhaps up snow-covered ridgelines to vantage points with mountains towering overhead and ice-speckled oceans below. If you have chosen an optional activity, you will have the option to do that whenever conditions allow, and of course keen polar plungers will have the chance to fully immerse themselves in polar waters-conditions permitting!

In addition to Zodiac cruises and shore excursions, you may ship cruise some of the narrow, dramatic straits separating offshore islands from the mainland, or linger in scenic bays to watch whales travelling or feeding. Keep an ear out for the creak and deep rumble of glaciers as they carve their way from summit to sea. Take a quiet moment to experience the wonder of this incredible white continent.

On this voyage, conditions permitting, plan to cross the Antarctic Circle, an imaginary line located at the Antarctic Circle at latitude 66°33′ South (approximately). Crossing below The Circle is certainly a special highlight for many people, and the moment will be celebrated with a toast out on the deck (weather permitting). You have earned some boasting privileges, joining a small group of lucky adventurers who have ventured to this part of the world.

As you approach and cross the Antarctic Circle, notice subtle changes in the landscape, and also in the distribution of wildlife. The waters at this time of year are rich with krill, so hope to see plenty of whales-particularly humpbacks and minkes-and enjoy the spectacle of penguins feeding their ravenous chicks.

ACCOMMODATIONS Greg Mortimer, Sylvia Earle
MEALS Breakfast, Lunch, Dinner

Enjoy a final morning landing in the South Shetland Islands before you re-enter the Drake Passage for your return journey to South America.

With lectures and film presentations to complete your Antarctic experience, there is still plenty of time to enjoy the magic of the Southern Ocean and the life that calls it home. There is time for reflection and discussion about what you have seen and experienced. Become an ambassador for Antarctica by telling your family, friends and colleagues about your journey to this magical place, advocating for its conservation and preservation so that they might one day visit the region to experience what you have been lucky to see and do here.

As you approach the tip of South America, your captain may sail close to legendary Cape Horn, weather and time permitting.

ACCOMMODATIONS Greg Mortimer, Sylvia Earle
MEALS Breakfast, Lunch, Dinner

During the early morning, cruise up the Beagle Channel before quietly slipping into dock in Ushuaia, where you will be free to disembark around 8:00am. Say farewell to your expedition team and fellow passengers as you all continue your onward journeys, hopefully with a newfound sense of the immense power of nature.

Upon disembarkation, for those continuing their travels in the region, transportation to the hotel will be arranged exclusively for guests who have booked their accommodations through the ship or for those staying in downtown areas near the port. Expeditioners departing on flights prior to 12:30pm will be directly transferred to Ushuaia Airport, those with flights after 12:30pm will have the opportunity to explore Ushuaia before an afternoon airport transfer, and the transfer procedures and details will be communicated on board before disembarkation.
