Poseidon Expeditions

Poseidon Expeditions is a polar cruise specialist, running expert-led voyages to Antarctica and the Arctic. Founded in 1999, the company combines intimate small-ship travel with hands-on exploration, and it builds each trip around environmental responsibility, guest education, and wildlife conservation. The result is access to some of the most remote and unspoiled places on Earth.

A Ship Built for Polar Adventure

Poseidon Expeditions operates the M/V Sea Spirit, an ice-strengthened expedition ship built for polar navigation. With just 114 guests, it stays roomy yet intimate, which allows personalized service and longer time ashore. A fleet of Zodiacs (sturdy inflatable landing boats) carries guests close to glaciers, icebergs, and wildlife for a real hands-on expedition.

Destinations Include

• Antarctica: the Antarctic Peninsula, South Georgia, and the Falkland Islands, with their ice formations, large penguin colonies, and marine life.
• The Arctic: the Svalbard archipelago, Greenland, and Iceland, with polar bears, walruses, and dramatic Arctic landscapes, plus North Pole voyages aboard a nuclear-powered icebreaker.
• Guided landings and expert-led excursions: wildlife encounters, scenic hikes, kayaking, and lectures led by marine biologists, geologists, and polar historians.

Commitment to Sustainability and Responsible Travel

Poseidon Expeditions follows strict environmental guidelines as a member of both IAATO and AECO. IAATO is the International Association of Antarctica Tour Operators, which sets the standards for responsible Antarctic travel, and AECO is its Arctic equivalent. The company backs conservation work and scientific research, and guests can join citizen-science programs that help monitor climate change and polar ecosystems.
