OVERVIEW

Undertake an incredible Antarctic journey to the sights of dramatic ice formations, magnificent icebergs and crackling ice. 
The Southern Expedition is a true Antarctic expedition that will take you across the legendary Antarctic Circle. From the South Shetland Islands to the Antarctic Peninsula you will encounter curious penguins, resting leopard seals and sightings of humpback whales. 

ITINERARY

Arrival in Buenos Aires

You may arrive in Buenos Aires at any time during Day 1 of your itinerary. Upon arriving in this splendid city, known for its architecture and rich European heritage, you will independently transfer to your group hotel (pre-expedition hotel night included in mandatory transfer package).

Fly to Ushuaia and Embark

After an early breakfast at the hotel, the group will transfer to the airport and board our private charter flight to Ushuaia, Argentina.

Upon arrival, you will be transferred from the airport to a central downtown location to have some time on your own to explore this quaint port town before making your way to the pier.

As the ship sets sail in the late afternoon, you will begin your Antarctic journey, passing through the Beagle Channel. Named after the famed ship on which Charles Darwin voyaged, the channel presents great photo opportunities of landscapes and seabirds. Eventually the channel opens up to the Southern Ocean, and onwards to Antarctica.

Crossing The Drake - Day 3 & 4

Your days at sea are filled with presentations and lectures led by your Expedition Team, who will prepare you for the wildlife that will greet you upon your arrival. In between presentations, spend time chatting with your shipmates over a drink at the bar, or enjoy the fresh air and views on the outer decks.

South Shetland and Peninsula - Day 5 to 7

The most common reaction upon reaching the White 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 cunning leopard seal.

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).

Antarctic Circle - Day 8 to 9

Crossing the Antarctic Circle is an impressive achievement, as most expeditions to the Antarctic Peninsula do not reach this far south — 66°33´S. If conditions allow us to cross this famed line at 66°33´ S, you and your shipmates will celebrate in style with a well-earned glass of sparkling wine!

Make a toast 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, Adelie penguins and some of the most awe-inspiring ice formations you’ll see anywhere on the planet.

Northbound Along The Peninsula - Day 10 to 11

By now, your knowledge of Adélie, chinstrap and gentoo penguins will be matched by your ability to differentiate between a leopard, fur 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.

Crossing The Drake - Day 12 to 13

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 great landing sites 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.

Disembarkation in Ushuaia and Fly to Buenos Aires

You will arrive in Ushuaia in the morning and disembark after breakfast. The mandatory transfer package includes a little taste of Patagonia with a Tierra del Fuego National Park tour before transferring to the airport for the return group charter flight to Buenos Aires.

*Please note: Cruise itinerary is subject to change depending on weather conditions, ice conditions and other factors.
