Antarctica

The northernmost finger of the Antarctic mainland, reaching toward South America; the most visited and most temperate region of the continent, with the majority of all Antarctic research stations and tourist landings concentrated along its western coast.

A volcanic island in the South Shetland Islands, forming the caldera of an active submarine volcano with a flooded crater that ships enter through a narrow channel; notable for geothermal activity, whaling history, and large Antarctic fur seal colonies.

A dramatic navigable channel between the Antarctic Peninsula and the mainland, approximately 11 kilometres long and flanked by steep glaciated mountains; considered one of the most scenic passages in Antarctica and a highlight of expedition cruise itineraries.

A series of ice-free valleys along the McMurdo Sound coast near Ross Island, representing one of Earth's most extreme deserts; characterised by bare gravel, ancient glacial deposits, and unique microbial ecosystems, and designated a UNESCO Specially Managed Area under the Antarctic Treaty.

A broad, sheltered harbour on the west coast of the Antarctic Peninsula named for its exceptional beauty; home to Argentina's Primavera research station and a favoured Zodiac landing site for expedition cruises.

A natural harbour on the western side of the Antarctic Peninsula, home to a restored British research station built in 1944 and designated as the first Historic Monument under the Antarctic Treaty; now a living museum and a noisy gentoo penguin colony.
