A rare and dramatic flat-topped volcano home to over 40,000 penguins
Information about Brown Bluff
Brown Bluff is a great example of a “tuya” - a volcano that has been flattened by erupting through a glacier! These are the rarest of all volcano types and only found in areas that have seen large-scale glaciation in the past.
Brown Bluff with its distinctive “tabletop” look, lies on the Tabarin Peninsula, in the northernmost part of the Antarctic Peninsula, and on landings when there is little snow, with the rock formations it is easy to think you are in Colorado rather than Antarctica!
The landing beach here is made of pebbles and volcanic ash, rising quickly towards steep reddish-brown cliffs. The cliffs are embedded with “volcanic bombs” - large pieces of lava that were thrown out during an eruption, cooling in the air to land as solid spherical or oval shapes.
As well as the fascinating geology, the other star of the show is the birdlife. Brown Bluff is home to over 20,000 breeding pairs of Adelie penguins, as well as a small colony of gentoo penguins. And long lines of penguins walk along the beach to the preferred location to get into the water - away from areas where Leopard Seals may be hiding in hidden gullies offshore. Other breeding residents for what is landing on the main peninsula, include storm petrels, Cape petrels, Snow Petrels and Kelp gulls.
Weddell seals often haul out on the beach here, and it’s also common to see Leopard seals hunting in the waters close to the shore.

Highlights Close to Brown Bluff
A gateway to the ultimate adventure that only a few will be lucky enough to experience.
Located at the northerly tip of the Antarctic Peninsula, the Sound is a remarkable onslaught for the senses as you come face-to-face with monstrous slabs of ice, now floating free as enormous tabular icebergs. These have broke away from ice shelves in the Weddell Sea and drifted into the Sound.
Treacherous to early explorers, the first vessel to successfully navigate the Sound was The Antarctic, the vessel of the Swedish Nordenskjold expedition of 1903. Unfortunately, she was trapped in the Weddell Sea by ice the following year and crushed - one of several vessels to have that fate over the decade.
Fortunately, modern polar cruising vessels have no such worries with their strengthened hulls and modern navigation technology. As you enter the monochromatic beauty of white ice and grey sea you will know that that you are soon going to experience some of the remarkable sights and encounter the wonderful wildlife that makes its home in these islands of snow, ice, and rock.
