D’Hainaut Island, Mikkelsen Harbour, Trinity Island

Home to a bustling Gentoo penguin colony and many artefacts from a past of whaling and exploration.

Information about D’Hainaut & Trinity Island

D’Hainaut Island is a tiny rock island in Mikkelsen Harbour. It’s less than half a square mile in size, and it’s approached through a small bay that’s lined with dramatic cliffs of ice. It was first mapped by a French expedition in 1910.

The island often remains snow-covered until very late in the season, and the captain of your Antarctic cruise vessel will expertly navigate through the shallow reefs that are in the bay.

This island was used extensively for whaling, and there are artifacts and bones dotted around the island. D’Hainaut is one of the few Antarctic visitor sites where you can roam freely around the whole island, taking care not to disturb any of the artifacts and watching your step on the rocks, of course.

There is a small historic refuge here that was built originally by the Argentine Navy in the 1950s, then again in the 1970s, and most recently in 2017. However, the refuge can’t be entered except in emergencies.

There is also plenty of evidence of the whaling industry on the island. You can find the wrecks of several boats as well as many whale bones. There is a lively Gentoo penguin colony here, and you can often find Fur Seals basking in the sun.

Interesting facts about D’Hainaut & Trinity 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.
