About Poseidon Expeditions

Poseidon Expeditions was founded in the U.K. in 1999 and has since grown into a leading polar cruise operator. With its headquarters in Cyprus and representations and offices in the UK, US, Germany, and China, the company markets travel programs worldwide.
Whether you seek to explore the Arctic with destinations like Greenland, Svalbard, the British Isles, and Iceland or venture to the White Continent to see Antarctica, South Georgia, and the Falkland Islands, Poseidon Expeditions knows how to make this adventure the trip of a lifetime.
Poseidon Expeditions is passionate about old-school expedition cruising, where the most important part is the time travelers spend off the ship, enjoying untouched nature and iconic wildlife. For this reason, Poseidon Expeditions has chosen the small expedition vessel M/V Sea Spirit, with a maximum capacity of about 100 guests. The Sea Spirit is highly maneuverable and capable of navigating the narrow fjords of Greenland and entering the small bays of Spitsbergen, as well as allowing all guests to have maximum time on shore in Antarctica, where no more than one hundred guests can land at one site at the same time.
Poseidon’s edutainment program and friendly atmosphere ensure that guests are not only active outdoors but also enjoy every single moment aboard. Polar experts and special guests provide fascinating lectures and presentations, bringing the world of the Arctic and Antarctica closer to the passengers.
The company is also committed to safe and environmentally responsible polar travel. It is a member of the International Association of Antarctica Tour Operators (IAATO) and the Association of Arctic Expedition Cruise Operators (AECO).
