Astrolabe Island

Astrolabe Island

Come face to beak with chinstrap penguins on a crescent moon-shaped beach.

Astrolabe Island in 3 miles long, and can be found about 14 miles off the Cape Ducorps in the Bransfield Strait on the Trinity Peninsula. It was discovered in 1837 and named after the French expedition ship that found it.

There is a wonderful crescent beach on the northern shore which is where you will land. Depending on the time of year you might have to pick your landing spot carefully to avoid the Antarctic fur seals who breed here and can be aggressive if they have very young pups.

The main attraction is the chinstrap penguin colony, several thousand strong. On your way in or out of this site, you will no doubt sail close to a group of impressive rocks that stick out of the sea to the northeast, known as the Dragon’s Teeth. Some of our expert Antarctic cruise guides have decided that if your ship sails in between any of the teeth, that means you have “flossed” Astrolabe Island!

Mawson’s Huts and Cape Denison

Cape Denison is at the eastern edge of the Australian Antarctic Territory at the head of Commonwealth Bay. The peninsula is mostly free of ice and made up of a series of rocky valleys and ridges. The importance of the Cape to Antarctic human history lies in the collection of buildings known as Mawson’s Huts. These were built and lived-in during an Australian Antarctic Expedition that ran from 1911 to 1914, led by the explorer and geologist Sir Douglas Mawson. The huts that now bear his name are very rare, being only one of six sites that still remain from the so-called “heroic era” of Antarctic exploration. There are several buildings that were constructed to house scientific instruments, including taking magnetic readings and astronomical observations. There was also a radio hut - the first time radio transmission was used in the Antarctic. The main hut at Cape Denison has undergone some preservation work but snowfall can still often get inside. Because of the delicate nature of the hut, only 4 people at any time are allowed inside. There you can find an amazing time capsule from the early 20th century, including the cast-iron stove, bottles, jars, cans, and other everyday items. Some of the storage shelves have the names of the men who placed their belongings there written on them with the date - still legible after 120 years. Apart from Mawson’s Huts, Cape Denison is a popular spot for breeding wildlife. Weddell seals can often be seen with pups during the breeding season, and there are also bird colonies including skuas, petrels, and penguins.
