Join us on this 15 days in-depth expedition of the Antarctic continent that very few travelers have ever been so far south. Cross the Antarctic Circle, and explore seldom visited iceberg graveyards and scientific bases, spend great times communing with penguins and visiting less-frequented landing sites. Antarctica is a spectacular destination, truly like no other place on earth; we invite you to enjoy the abundant wildlife, including Orcas, Humpback and Minke whales, in addition to  Weddell, Leopard, and Crab-Eater seals and a wide variety of birds.

Arrive Ushuaia

Welcome to Ushuaia, the world’s southernmost city and starting point of our Antarctic expedition! Upon your arrival at the airport, you will be greeted by our staff and transferred to a quality hotel, which has been arranged by us and is included in the price of the itinerary. For the rest of the day, you are free to explore this vibrant port city and adventure hub.

For an introduction to local history and wildlife, the interesting Museo del Fin del Mundo is worth a visit. If you have time to spare, a variety of nature activities can be arranged to suit all interests and fitness levels, from hiking in nearby Tierra del Fuego National Park to wildlife viewing in the Beagle Channel. For dinner, Ushuaia offers a wide range of restaurants featuring Patagonian lamb and delectable Fuegian seafood.

Embarkation in Ushuaia

After breakfast at your hotel, the morning is yours to enjoy Ushuaia. Explore the delightful waterfront and savor views of the snowcapped Martial Range, the southernmost peaks of the Andes. Take advantage of shopping for souvenirs or some last-minute necessities such as cold-weather gear. Just remember, you will soon receive your very own parka to keep and waterproof boots to borrow on board the ship. For lunch, the many cafés, parrillas and gelato shops on Avenida San Martín will be sure to satisfy any appetite.

In the afternoon, you will be transferred to the pier where we will warmly welcome you aboard the deluxe expedition vessel M/V Sea Spirit. Get settled in your spacious suite and explore the ship that will be your comfortable home during the extraordinary adventure to come. After getting underway, a full schedule of events kicks off with informative briefings and introductions from your expedition staff. After the first of many delicious dinners on board, step out onto the open decks to admire the scenery and gorgeous evening light as we pass through the Beagle Channel.

Across the Drake Passage - Day 3 & 4

After passing the islands of Tierra del Fuego, we turn south to begin our crossing of the Drake Passage. We watch for humpback and fin whales along the way. The majestic wandering albatross and other graceful subantarctic seabirds are common in these waters and can readily be viewed from panoramic open decks and balconies. We also cross the Antarctic Convergence, the biological boundary of the Southern Ocean. The ship’s stabilizing fins provide comfort in the event of rough seas. Briefings, bio-security procedures and presentations by our lecture staff prepare you for our arrival in Antarctica. We hope to arrive in the South Shetland Islands on the evening of our second day at sea.

South Shetland & Antarctic Peninsula - Day 5 to 12

Within the next days, we undertake an in-depth exploration of the South Shetland Islands and the Antarctic Peninsula. This region contains some of the world’s most impressive scenery and the best wildlife viewing in Antarctica. Sheltered bays and channels sparkle with ice and reflect towering mountain peaks coated in permanent snow and immense glaciers. Icebergs of every size and description complete an image of incomparable beauty. Waters rich with krill are home to huge numbers of marine mammals and seabirds. The whole area is alive with penguins foraging at sea and forming large rookeries at special places on land. Here we also find Antarctic research bases of various nationalities.

The South Shetland Islands are the northernmost islands in Antarctica and will likely be our first area of exploration. This wildly beautiful island chain contains many landing sites with historical significance and abundant wildlife. We will also explore the supremely picturesque Gerlache Strait area of the Antarctic Peninsula, a pristine wilderness of spectacular white landscapes, colossal icebergs, obliging marine mammals and bustling penguin colonies. We plan to pass through the famous Lemaire Channel, also known as “Kodak Gap” because of the photogenic way the narrow channel reflects the image of sheer snowy mountains.

On this special voyage, we have additional days devoted to pushing even farther south in our attempt to cross the Antarctic Circle. The sublime icescapes in Crystal Sound and beyond are particularly austere, the weather is especially wild, and the waters are full of constantly shifting ice. Very few people have ventured this far south. This is a true expedition.

Throughout the islands and on the mainland, we find large colonies of gentoo, chinstrap and Adélie penguins, sometimes side by side. It is a dramatic time at the colonies. While some parents remain at the nest to guard against skua attack, others go fishing in seas patrolled by predatory leopard seals and killer whales. Meanwhile, fluffy chicks are starting to explore away from their nests. Also at this time, humpback and minke whales have arrived in great numbers and the feeding frenzy in is full swing. Crabeater and Weddell seals abound in these highly productive waters.

In this rugged yet accessible environment, superb wildlife viewing is best complemented by active adventure. For sea kayakers, the wildlife-rich waters of Antarctica offer many chances to paddle with seals and penguins in some of the world’s most scenic waterways. To make the most of your time on the White Continent, you can also spend a night camping ashore, surrounded by untamed Antarctic nature.

This is expedition cruising at its most authentic. Our precise route and exploration opportunities will be shaped by weather and ice. Our experienced captain and expedition leader will continually adjust plans to take maximum advantage of the conditions in this challenging polar environment.

Back across the Drake Passage - Day 13 & 14

It is now time to head back across the Drake Passage toward South America, but the adventure is not quite over. Seabirds are our constant companions and there is always the possibility of whale encounters in these wild waters. This is also the time for festivities such as the Captain’s Farewell Cocktail and the end-of-voyage slideshow. Finally, as we enter the calm Beagle Channel, we enjoy a night of smooth sailing toward Ushuaia.

Disembarkation in Ushuaia

After yet another delicious breakfast on board, we bid you a fond farewell in Ushuaia. We provide a group transfer to the airport or to the city center if you wish to spend more time here. As you look back on your wonderful experience in Antarctica, you may already be looking forward to your next polar adventure!

*Important - Please be sure not to book flights out of Ushuaia before 12PM (Noon) on the day of disembarkation from your cruise ship.



  • This 15 day in-depth voyage takes you further south than most of the Antarctic Cruises: venturing past the Antarctic Circle.

  • You will have the possibility to step foot on the great white continent to experience some of the most unique wildlife and inspiring scenery in the world.

  • Few travellers have ventured this far south, but with our fully equipped ice-strengthened vessel and hopefully favourable sea conditions we can access many remote locations that other ships cannot reach.

  • On this particular voyage, we have additional days set aside to push even further south in our attempt to explore the landscape around the Antarctic Circle which is especially desolate. The weather here is particularly wild, and the waters are full of constantly shifting ice.

  • The expedition team will assist with your Antarctic experience. They will provide you with insights on everything Antarctic - from the history and geology, to the incredible wildlife.

Sea Spirit

Sea Spirit

Explore the Polar Regions in style and comfort aboard the all-suite Sea Spirit. Providing spacious suites and social areas for 114 guests the Sea Spirit at the same time features manoeuvrability and friendly atmosphere of small ships. In 2017, she was renovated to offer a unique mixture of adventure and comfort, so your surroundings while aboard will be the perfect cosy complement to the icy landscapes outside. 

Sea Spirit has been retrofitted with Rolls Royce Zero Speed Stabilizers that allow safe, stable navigation through icy waters. The operational benefits of the new retractable fin stabilizers include reducing the ship's roll when anchored, moored, or drifting, reducing dynamic drag when deployed while underway, and eliminating vibration and noise.

All suites have ensuite facilities, exterior views and are equipped with king-size beds or twin beds if preferred. Deluxe Suites, Premium Suites and the Owner's Suite have private balconies for viewing the breath-taking landscapes of the polar regions. The public areas include a Reception, Restaurant, Bar, Outdoor Bistro, Club Lounge, Library, Presentation Lounge, Infirmary, Gym, and Bridge. There is an open Bridge policy so you can talk to the captain and officers at any time. Enjoy the amenities of a fine hotel, while a resident photographer helps you take brag-worthy photos.
