Expedition Semi-Circumnavigation Antarctica: A Route That Only A Few Have Ever Completed

Ushuaia, the southernmost city in the world, is a captivating blend of history, vibrant culture, and natural beauty, making it a unique port of call in Argentina. Must-do experiences include savoring local delicacies like centolla and exploring the breathtaking landscapes of nearby Los Glaciares National Park. The best time to visit is during the summer months of December to March, when the weather is mild, and the scenery is at its most stunning.

The Shetland Islands, Britain's most northerly archipelago, offer a dramatic blend of Norse heritage, spectacular seabird colonies, and raw Atlantic landscapes 60 degrees north. Must-dos include the puffin colonies at Sumburgh Head, the ancient Mousa Broch, and sampling Shetland lamb and hand-dived scallops. Visit May through August for the magical "simmer dim" near-perpetual daylight.

Cape Royds on Ross Island is a remarkable Antarctic site where Shackleton's 1908 expedition hut stands perfectly preserved beside the world's southernmost Adélie penguin colony, with Mount Erebus's volcanic plume rising behind. Must-dos include entering the Shackleton hut to see provisions frozen in time, observing the Adélie penguin colony, and viewing Mount Erebus's lava lake from a distance. Visit January for the warmest conditions, accessible only via Ross Sea expedition cruises.

Balleny Islands, New Zealand, showcases the Southern Hemisphere's remarkable natural heritage—pristine coastlines, unique wildlife, and landscapes of ancient geological drama. Must-do experiences include sampling the exceptional local seafood and exploring the surrounding national parks. The most rewarding visiting window is November through February, when the austral summer brings the longest days and mildest conditions. Cruise lines including Ponant feature this port on their most compelling itineraries. Whether you have a few hours or a full day, the port rewards exploration at every pace and in every direction.

Oban on Stewart Island is New Zealand's southernmost settlement, gateway to Rakiura National Park's pristine native forest and some of the world's best wild kiwi viewing. Must-dos include an evening kiwi-spotting excursion to Ocean Beach, birdwatching on predator-free Ulva Island, and eating blue cod at the South Sea Hotel. Visit December to February for the warmest weather or March to May for Bluff oyster season and southern lights.
