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

Information about Astrolabe Island

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!

Port Charcot, Booth Island

Port Charcot is a small bay at the north end of Booth Island. Booth Island is a rocky and rugged Y-shaped island off the Kiev Peninsula in Graham Land. It was first mapped in 1904 when the French Antarctic expedition led by Jean-Baptise Charcot over-wintered here.

After building a few rudimentary shelters and the cairn that can still be seen at the top of the hill, the expedition used Port Charcot as its base for exploring the area, that is close to the Lemaire Channel and the division between the NW and the SW peninsula . There is the remains of a stone hut used for astronomical observations and a wooden pillar with a plaque here where you can still make out the names of the first expedition members who wrote them almost 120 years ago.

In the bay where the Français was anchored (but difficult to reach with the ice) the letter 'F' was carved onto the rocks and can still be seen.

The walk to the cairn is delightful, although you’ll be carefully led by guides as wandering off the path can be treacherous, with loose rocks and crevasses. Visitors can also walk to the east where there is a noisy Gentoo penguin colony. Chinstraps and Adelies can also be seen on the beaches here. If you are lucky, you might get all three together!

From the top the views are stunning, especially the view to the SW, towards Pléneau Island Island, overlooking 'the iceberg graveyard'. This iceberg graveyard can be explored on a spectacular Zodiac cruise, either from ships anchored off Port Charcot to the 'NW' of the Lemaire Channel, or from ships anchored off Pléneau Island and Booth Island that had sailed through through the Lemaire Channel. For full details of this Zodiac cruise refer to the details under Pléneau Island.
