Poseidon Expeditions is one of the leading providers of polar expeditions in the cruise industry. Founded in 1999, the company is a recognized leader in icebreaker cruises to the North Pole, the Arctic and Antarctica. With the 116-passenger Sea Spirit, Poseidon expanded its offerings to include deluxe expedition cruises to Antarctica, and to the Arctic destinations of Svalbard, Greenland, Franz Jo

sef Land and Iceland. With representations and offices in the UK, US, Germany, Cyprus and China, the company markets it travel programs worldwide. As a member in good standing of both the Association of Arctic Expedition Cruise Operators (AECO) and the International Association of Antarctica Tour Operators (IAATO), our company pledges its commitment to the further development of Arctic and Antarctic conservation and support of related scientific research. We actively encourage participation in our expeditions by naturalists and scientists engaged in such research, offering a platform from which they can pursue their important work as well as a forum where they can voice their unique understanding of these fragile and remote ecosystems. Preservation of the Arctic and Antarctic habitats and the Polar Ice Cap are environmental imperatives and the responsibility of all, including tourism operators and their guests. We at Poseidon Expeditions are honored to be a part of this, and to help our passengers understand the importance of preserving Polar Regions for future generations.

ยซThe size of the ship is a very strong unique selling pointยป

We couldnโ€™t agree more.

Speaking from her firsthand experience aboard Sea Spirit, Akvile Marozaite, CEO and Co-founder of Expedition Cruise Network and a speaker at the International Women in Travel & Tourism Forum, explains why small ships create a completely different expedition experience.

More flexibility. More time ashore. More opportunities to explore.

Sometimes, the smallest ships leave the biggest impressions.

Would you choose a small expedition ship?

Our expeditions are designed to bring you closer to the polar world.

Sea kayaking takes that idea even further. Itโ€™s one of the most immersive ways to connect with nature.

๐Ÿ“ What to know before you go:

๐Ÿ”น Optional activity that must be booked in advance.
๐Ÿ”น Small groups led by experienced guides.
๐Ÿ”น Basic kayaking experience and a basic level of English required.
๐Ÿ”น All specialized equipment provided.
๐Ÿ”น Available on many Arctic and Antarctic expeditions.

Iceland Circumnavigation is back for 2027! ๐ŸŒ‹

Next summer, weโ€™ll return to one of our rarest Arctic itineraries โ€” a full circumnavigation of Iceland aboard the Sea Spirit.

This is not a voyage we offer every season. In fact, the last time we operated this itinerary was 10 years ago โ€” which makes its return truly special.

Over 10 days, weโ€™ll explore Iceland from every side: dramatic fjords, volcanic landscapes, remote coastal villages, seabird cliffs, waterfalls, and wild places that feel made for expedition cruising.

๐Ÿ“… Dates: June 1โ€“10, 2027

Some places in Antarctica feel dramatic even before you step ashore โ€” and Deception Island is one of them. A volcanic island defined by black sand and rugged cliffs, it feels unlike anywhere else in the Antarctic.

Its wildest side, Bailey Head, is home to a vast chinstrap penguin colony โ€” penguins everywhere, crossing the black volcanic shore and gathering in huge groups. The sheer scale instantly reminded us of South Georgia ๐Ÿง

Bailey Head is not a place every expedition gets to visit. But with the right conditions โ€” and the right expedition team โ€” moments like this become possible.

Join us to explore places few travelers ever get to see!
