Poseidon Expeditions is a leading operator of polar expeditions in the cruise industry. For 25 years we are offering voyages to the Arctic and Antarctica that combine the spirit of adventure with a generous measure of onboard comfort and well-being.

Our fleet goes where other ships cannot follow. Our small expedition ship Sea Spirit can navigate into protected channels and bays that are out of bounds to larger cruise ships. Importantly, her smaller passenger numbers mean that everyone can go ashore simultaneously at landing sites in Antarctica and the Arctic where regulations limit the number of visitors ashore. Our icebreaker 50 Years of Victory is perfectly suited to cruising across the frozen Arctic Ocean. She is the only vessel currently capable of fulfilling your dream of reaching the  North Pole !

Small ship – big advantage

Our small ship maximizes travelers' time ashore by eliminating the need for group rotations during landings, which are common on larger vessels.

25 years of polar experience

Over the past 25 years, we’ve gained tremendous experience building a strong team of enthusiastic polar professionals who are all experts in their field.

Environmental responsibility

As active members of AECO and IAATO, we support cleanup initiatives, enforce no-waste policies, and reduce our footprint with our small expedition ship.

Safety and comfort

Expedition cruising with Poseidon ensures active, yet safe polar exploration. Our highly trained team of professionals will help you navigate into the polar worlds in maximum possible comfort and safety.

Expedition team excellence

Our guests continually rate our expedition team as top-notch, highlighting their expertise in their field, knowledge, professionalism, and commitment to making each expedition cruise truly unforgettable and life changing.

The balance between luxury and expedition is another important factor that we have carefully considered. We pride ourselves on offering the perfect combination of both. Our ships provide a high level of comfort and amenities, while our crew and staff deliver the extraordinary service expected by discerning cruise-travelers. At the same time, we offer exciting excursions and adventure options to satisfy your inner thrill-seeker. All of this is available on itineraries that take you deep into the most remote areas of the planet, fulfilling your desire for real expedition.

This careful balance is reflected in the elegant and easygoing atmosphere on board. On our ships you can enjoy an authentic and exciting adventure as well as relaxation with friends, all in exceptional comfort and style.

High Latitudes Loyalty Program

To express our appreciation to our loyal travellers, we’ve created the High Latitudes Loyalty Program. With this program, our guests enjoy savings on any future trips with Poseidon Expeditions and are also able to take advantage of other attractive benefits listed for each level of our Polar Circle Loyalty Cards. The amount of savings and the benefits depend on the number of trips taken with us.

These benefits are for the exclusive use of the repeat traveller. However, the Polar Circle Loyalty Card itself – and the savings discount amount – is transferrable and can be passed along to a friend or family member. It could be their entry ticket to the amazing polar world of Poseidon Expeditions.

We look forward to welcoming you back aboard!
