Day 1: Arrive in Ushuaia, Argentina

Welcome to Ushuaia, the world’s southernmost city and starting point of your expedition. Upon your arrival at the airport get transferred to your hotel, which has been arranged and is included in the price of the voyage. For the rest of the day you are free to explore the city. Take advantage of souvenir shopping and a variety of dining options in the city center.

Day 2: Ushuaia | Embark

  • Ship
  • 1 Breakfast, 1 Dinner
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 luxury 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.

Day 3-4: Crossing the Drake Passage

  • Ship
  • 2 Breakfasts, 2 Lunches, 2 Dinners
After transiting the Beagle Channel and passing the islands of Tierra del Fuego, head south across the Drake Passage. Pelagic seabirds including the majestic albatross are common in these waters and can readily be viewed from panoramic open decks or from exterior stateroom windows and balconies. On the way you 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, orientations, and lectures from the expert staff prepare you for your arrival in Antarctica.

Day 5-12: South Shetland Islands | Antarctic Peninsula

  • Ship
  • 8 Breakfasts, 8 Lunches, 8 Dinners
This is expedition cruising at its most authentic. The route and exploration opportunities in Antarctica are heavily dependent on weather and ice conditions. The experienced captain and expedition leader decide the itinerary and continually adjust plans as conditions and opportunities warrant. Take advantage of long daylight hours to exploit every opportunity to experience excellent wildlife viewing, amazing scenery, and excursions via Zodiac.

The Antarctic Peninsula region contains some of the world’s most impressive scenery and some of Antarctica’s best wildlife viewing opportunities. Protected bays and narrow channels are surrounded by towering mountain peaks covered 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 a variety of whale and seal species. The whole area is alive with penguins foraging at sea and forming large nesting colonies at special places on land. The area is also home to Antarctic research stations of various nationalities. Some stations have a gift shop and post office.

The South Shetland Islands are the northernmost islands in Antarctica and are likely to be the first sighting of land. This wild and beautiful island chain contains numerous landing sites with abundant wildlife and historical significance. Among them is Deception Island, where the flooded caldera of an active volcano harbors an abandoned whaling station.

Farther south, on the Antarctic Peninsula, the vast Gerlache Strait area contains sheltered bays, accessible wildlife, and stunning scenery. Places with names like Paradise Bay are the epitome of everything Antarctic: glaciated mountains, towering icebergs, feeding whales, seals on ice floes, and bustling penguin colonies. At the southern end of Gerlache Strait is the famous Lemaire Channel, also known as “Kodak Gap” because of the photogenic way the mountainous sides of the narrow channel are reflected in calm waters strewn with icebergs.

On this special voyage have additional days set aside to push even farther south in your attempt to cross the Antarctic Circle. The landscape down here is especially desolate, the weather is particularly wild, and the waters are full of constantly shifting ice. This is real expedition cruising. Your days in Antarctica are filled with memorable excursions, sumptuous meals, presentations by experts, and enough incredible scenery and wildlife to fill your camera and overwhelm your emotions.

Day 13-14: Back across the Drake Passage

  • Ship
  • 2 Breakfasts, 2 Lunches, 2 Dinners
After your amazing time in Antarctica cross back north through the bountiful waters of the Drake Passage. Presentations and workshops by the expert staff, as well as a range of onboard recreation facilities, ensure that these days at sea are not idly spent. This is also the time for End of Voyage ceremonies including a slideshow and farewell dinner.

Day 15: Ushuaia, Argentina | Disembark

  • 1 Breakfast
After breakfast say farewell in the city of Ushuaia, where you started. Be transferred to the airport or to the town 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 incredible adventure to the ice!
