Icy and remote, the South Shetland Islands are situated about 100 miles north of the Antarctic peninsula. The archipelago is home to a scattering of research stations, along with thousands of penguins, seals and sea lions, and you can still see the remains of Ernest Shackleton’s ship the ‘Endurance’ on the south west shore of Elephant Island.

Perched on the ragged southern edge of Argentina, where the snow-capped Andes fall away into the churning sea, Ushuaia has a frontier town feel to it, and serves as the base for expeditions into the icy waters of Antarctica.

Surrounded by notoriously treacherous waters and battered by gale force winds known as the Furious Fifties, Cape Horn is the dramatic southernmost headland of the Tierra del Fuego archipelago. This is the point where the Atlantic and Pacific Oceans meet, watched over by a lonely lighthouse.

Puerto Williams has the feel of a true frontier town, situated on windswept Navarino Island facing out across the Beagle Channel. The surrounding mountains offer a spectacular backdrop for hiking and kayaking, while to the south lies the infamous Drake Passage and, beyond that, the frozen continent of Antarctica.

Puerto Natales, situated at the southern end of the Chilean Fjords, is a major tourism hub for southern Patagonia. Formerly a fishing port, the town is now the gateway to the Torres del Paine National Park, a spectacular landscape of granite peaks, grassy steppes and azure lakes, populated by guanacos, condors, pumas and more.

The little fishing village of Caleta Tortel hugs the base of a mountain, perched above turquoise waters fed by glaciers. There are no cars or horses in Caleta Tortel - instead, the piers and houses are connected together by a remarkable network of wooden boardwalks.

Rugged and unspoilt Chiloé, situated at the southern end of Chile’s Lake District, is a unique and culturally distinct island that stands apart from the rest of the country. The main town, Castro, is notable for its colourful waterfront homes on stilts (known as palafitos), and is the gateway to the dense forests and rolling hills of the island interior.
