Puerto Williams is a small Chilean city on Navarino Island, south of the Beagle Channel, and it calls itself the world's southernmost city, though nearby Ushuaia also claims that title. Surrounded by dramatic, snow-dusted mountains and the Dientes de Navarino, it was originally home to the Yaghan people. Founded as a naval base in 1953, it now serves Antarctic travel and offers a quiet, village-like alternative to bustling Ushuaia.

A north-westerly outpost of the Falklands, West Point Island greets visitors with vast colonies of black-browed albatross. Formerly Albatross Island, it's home to rockhopper, Magellanic, and imperial cormorant colonies, plus sheep and a tiny human population. Hike quiet landscapes to find endemic plants like Felton's flower, dramatic cliffs, and Cliff Mountain, the archipelago's highest cliff. Offshore, look for Commerson's dolphins, whales, and fur seals.

Saunders Island, northwest of the Falklands, is remote, wild, and rich in wildlife. Settled by the British in 1765 at Port Egmont, it's now sheep-grazed land with dramatic beaches and dunes, and some of the archipelago's best birdlife. See elephant seals, silvery grebes, Peale's dolphins, king penguins, Gentoo, Rockhopper and Magellanic penguins, black-browed albatross, and rare black-necked swans. Mount Richards (457m) offers wide views to Carcass and West Point islands.

Despite its British feel, Stanley is more Patagonia than Portsmouth. The Falklands' vast, windy beauty is mixed with pubs, fish and chips, whalebone landmarks, and Union Jacks. Long disputed among France, Britain, Spain and Argentina, the islands stayed British after the 1982 war and remain in the Commonwealth. Thatcher is still a local hero. The real stars are the penguins: five species, including rockhoppers, nest here with little barrier between visitors and wildlife.

South Georgia's snow-capped mountains, giant glaciers and abundant wildlife make it a great natural island. In this remote UK territory, animals rule: elephant seals clash, birds call, and vast king penguin colonies crowd the shore, joined by macaroni penguins and wandering albatrosses. Once a whaling center, it now preserves old stations. Linked to Shackleton's 1916 survival, it holds a museum and his memorial.

Elephant Island is one of Antarctica's best-known sites, famed for its stark beauty and Shackleton's 1916 survival story. Named for the elephant seals seen there by early explorers, it was the refuge where Shackleton and 28 men spent four and a half months at Point Wild. See the Endurance Glacier, the Shackleton monument, and gentoo penguins-an iconic stop on any Antarctic cruise.

The South Shetland Islands lie off the Antarctic Peninsula, separated by the Bransfield Strait and governed by the Antarctic Treaty. They host many research bases, along with elephant seals and large penguin colonies. King George Island has most stations. Highlights include Mount Foster, Deception Island's caldera and warm Pendulum Cove, and Elephant Island, famed for Shackleton's 1916 survival.
