Voyage Overview

Get a bird’s eye view of the Antarctic Peninsula & cross the Circle.

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 snow petrels soaring above the crackling sea. 

The technologically-advanced Ultramarine, the first ship built specifically for the Polar Regions, with its two twin-engine helicopters, 20 fast-launching Zodiacs, superior luxury amenities and the most robust portfolio of off-ship adventure options in the industry, completely changes the way guests explore the Antarctic.

Itinerary

Day 1: Arrive in Buenos Aires, Argentina
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).

Day 2: 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.

Day 3 – 4: Crossing the Drake Passage
Your days at sea are filled with presentations led by your Expedition Team on photography, wildlife, glaciology, and history In between presentations, spend time on deck looking for wildlife or chatting with your shipmates over a drink at the bar.

Day 5 – 7: South Shetland Islands and Antarctic Peninsula
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 elusive leopard seal. 

Your Expedition Team will take care of you at each landing, whether you are exploring the Antarctic terrain, visiting a research station 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).

Day 8 – 9: Antarctic Circle
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.

Day 10 – 11: Northbound Along the Peninsula
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.

Day 12 – 13: Crossing the Drake Passage
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.

Day 14: Disembark 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.

EXPEDITION SPIRIT: Embracing the unexpected is part of the legacy—and excitement—of expedition travel. When traveling in extremely remote regions, your Expedition Team  must  consider  the sea, ice and weather to guide the route and itinerary details. This itinerary is a tentative outline of what you may experience on this voyage; please  be  aware  that  no  specific  itinerary can be guaranteed. By the same  token,  wildlife  encounters  as  described  are  expected,  but  not  guaranteed.  Your  Expedition  Team  will  use  their  considerable  experience to seek out wildlife in known habitats, but the presence of any particular species of bird or marine wildlife is not guaranteed.
