Our Sub-Antarctic Sea Voyages

Our Sea Voyages to the Sub-Antarctic region are high-end wilderness adventures. All of these trips are on board our newest and most modern polar vessel, Magellan Explorer. Feeling more like a private yacht, our small expedition ship gives you privileged access to Antarctica, South Georgia, the Falkland Islands, and Patagonia & Chilean Fjords.

With a smaller number of guests, disembarkation is fast and efficient so you spend time exploring the following destinations:

The Falklands Islands
The Falklands Islands (Islas Malvinas) are a mix of rich wildlife, interesting culture, and storied history.

South Georgia
On this island, filled with snowy peaks jutting out of the sea, there are no permanent human residents, and wildlife rules.

Patagonia & Chilean Fjords

With rugged mountains, glaciers, and pristine lakes, this region is characterized by striking natural beauty. It is also home to the Southern Patagonian Ice Field, one of the largest ice fields outside the Polar Regions.

Antarctic Peninsula
See peaceful bays dotted with colossal icebergs, cruise along deep fjords and see massive glaciers, and be amazed by the extraordinary wildlife on land and at sea.

Small Ship, Big Adventures

Vessels Custom-Built for Polar Exploration

Feeling more like private yachts than cruise ships, our small expedition vessels give you privileged access to Antarctica and southern latitudes, taking you where larger ships cannot. With fewer passengers, disembarkation is fast and efficient, so you spend more time exploring, not waiting your turn to disembark and explore on Zodiac or on land.

Expert team of polar guides

Unparalleled Value

Your expedition will be led by an expert team of at least 12 polar guides. Our sea voyages have one of the highest staff-to-traveler ratios in the industry and offer an extensive list of trip inclusions for you to enjoy. Our rates start at only $6,495 USD per person, making these wilderness expeditions of extraordinary value.
