Wildlife on this route

Penguins

Emperor Penguins

The world's largest penguin breeds only in Antarctica's brutal winter. A rare and unforgettable sight.

Penguins

Gentoo Penguin

A stocky, orange-billed penguin of the genus Pygoscelis, closest kin to the Adélie and Chinstrap. Its loud, trumpeting call, delivered with head thrown back, carries across the shoreline colonies where expedition landings are made.

Whales & Dolphins

Humpback Whale

A 14–17 metre baleen whale known for breaching and long pectoral fins, often seen feeding on krill in loose groups along the ice edge.

Whales & Dolphins

Orca

Black and white apex predator instantly recognizable by its pale eye patches, the orca is the largest of the dolphins and one of the ocean's most capable hunters. Sightings often involve a tight-knit family pod working the ice edge together.
