Seabourn is growing its Antarctica programme for the 2026–27 season. There will be 19 voyages, each with a 21-member expert expedition team. The cruise lines are also extending their South Atlantic routes. This means travellers will get access to Antarctica, South Georgia and the Falkland Islands. These changes aim to give guests a meaningful experience, in these remote regions.

Seabourn will operate 19 Antarctica expeditions during the 2026–27 season, combining specialist-led exploration with voyages aboard Seabourn Venture and Seabourn Pursuit.

The programme will run from November 2026 to March 2027, with departures operating roundtrip from Ushuaia in Argentina. Most sailings will last between 10 and 12 days, while selected extended journeys of around 20 days will also visit South Georgia and the Falkland Islands.

Ushuaia Remains the Main Gateway to Antarctica

The season has been structured to make the journey south easier for international travellers.

Each Antarctica itinerary will include a pre-cruise hotel stay in Buenos Aires along with roundtrip charter flights between Buenos Aires and Ushuaia. Travellers will then board their expedition ship in Ushuaia before continuing towards Antarctic waters.

The arrangement reduces the need for guests to organise separate domestic connections and creates a more seamless route between Argentina’s capital and one of the world’s most important polar cruise gateways.

Specialist Teams Will Accompany Every Sailing

Every departure will carry a 21-member expedition team made up of professionals from different scientific and environmental fields.

Areas of expertise will include marine biology, wildlife research, conservation, geology, environmental science and polar history.

These specialists will support activities both ashore and onboard. Their role will include helping passengers understand the wildlife, landscapes, climate and geological features encountered during the journey.

Rather than focusing only on sightseeing, the expedition format will place strong emphasis on learning and interpretation throughout the voyage.

Shore Landings and Wildlife Viewing Add Depth

Travellers will be able to take part in shore landings, Zodiac outings, wildlife observation and educational sessions during the season.

Experts in marine mammals, seabirds and ecology will help passengers recognise species and better understand the behaviour of animals living in the Antarctic environment.

Other specialists will focus on glaciers, rock formations, ocean systems and the natural forces that continue to shape the continent.

The season will also bring together knowledge in subjects including whale research, ornithology, archaeology, astronomy, seabird science, ecology and natural history.

This broad mix of disciplines is intended to give travellers a more complete picture of Antarctica as both a destination and an important scientific environment.

Conditions Will Shape Daily Expedition Plans

Antarctica itineraries can change according to weather, sea ice, visibility and local operating conditions.

Daily landings and activities will therefore remain flexible. Expedition teams will assess safety and accessibility before deciding where and when passengers can go ashore.

Wildlife encounters may also differ from one sailing to another because animal movements and environmental conditions are never identical.

This flexible operating model is a normal part of expedition travel in polar regions and allows programmes to respond to conditions in real time.

Longer Voyages Extend Beyond Antarctica

Travellers wanting a more extensive journey will be able to choose selected 20-day itineraries that add South Georgia and the Falkland Islands.

These destinations expand the expedition beyond the Antarctic Peninsula and introduce passengers to additional wildlife habitats, coastal landscapes and historically significant locations across the South Atlantic.

The longer programme is aimed at guests seeking a wider polar experience rather than a single-region voyage.

Two Expedition Ships Lead the 2026–27 Season

Seabourn Venture and Seabourn Pursuit will operate the full programme through March 2027.

Both ships are designed for expedition cruising in remote regions while maintaining a luxury onboard environment.

Across the 19 scheduled departures, travellers will have a choice between shorter Antarctic voyages and extended sailings that include South Georgia and the Falkland Islands.

With scientific expertise, organised connections through Argentina and a strong focus on wildlife and environmental learning, the 2026–27 programme will offer travellers a structured way to explore one of the most remote regions on Earth.
