Snow Hill Island


You’ve got one main reason – or perhaps 10,000 – to visit remote Snow Hill Island off the east coast of the Antarctic Peninsula. Snow Hill Island is home to a rarely-visited colony of 4,000 pairs of breeding Emperor penguins and their offspring. That’s about 10,000 penguins in one relatively small space. The survival and breeding habits of this particular type of penguins have long fascinated nature-lovers. Not only do they thrive in bitterly cold temperatures – as low as -60°C (-76°F)–but they’re the only species of penguin to breed – and incubate their eggs – on ice rather than on shore.

Reaching Snow Hill Island is a challenge only a handful of travelers have achieved. In addition to crossing the notoriously rough Drake Passage, determined travelers must navigate the icy Weddell Sea by polar ship, and then take a helicopter flight before completing the trek on foot to the emperor penguin rookery.

Emperor Penguins at Snow Hill
Emperor Penguins

Emperor penguins are a fascinating breed. The largest of the 17 penguin species, Emperors (1.15 m or 45 inches tall) can dive deeper than any other bird, often reaching depths of 565 m (1,850 ft.), to hunt for fish, krill and squid. They can stay underwater for up to 22 minutes. Emperors are built to survive in -60°C (-76°F) temperatures and withstand blizzards of 200 km/hour (124 mph). Their four layers of scale-like feathers provide waterproofing and protection from harsh winds.

Unlike other penguins, Emperors breed on sea ice, not on shore. The female, after laying her egg, leaves the colony to hunt for food – but only after giving the egg to her male partner who carefully puts it on his feet and covers it with a layer of feathery skin called his brood pouch. The male will typically huddle with other adult males to protect their precious eggs from the frigid Antarctic conditions.

Tabular Icebergs

There are just as many types of icebergs in the Antarctic as there are penguins, especially in the Weddell Sea: Dome-shaped, wedge-shaped, tilted and blocky. Tabular icebergs are a particularly eye-catching iceberg. They’re created when icebergs break away from the ice shelf and are floating in the open water, easily recognizable by their plateau-like flat top and steep sides.

Iceberg Alley, Weddell Sea

One visitor described Iceberg Alley in the Weddell Sea as “…colossal tabular icebergs bigger than downtown buildings…luminescent in their blueness.” Iceberg Alley is the name given to a large concentration of icebergs in the western Weddell Sea. Imagine hundreds of icebergs of various sizes, as well as growlers (which are small icebergs) and bergy bits (chunks of glacier ice).

When to Go

Preferred Season

The preferred time to visit is November when it’s still possible to observe the newly-hatched baby penguins before they disperse. Ice conditions are more ideal at this time.

Special Insights from Our Guests

I feel very privileged to have been able to visit Emperor Penguin colonies on Snow Hill Island, Antarctica. This was of course made possible by Quark whose staff, as always, did an outstanding job of efficiency, flexibility and organization.
