Stretching from the west side of the Antarctic Peninsula to the Amundsen Sea, the Bellingshausen Sea was named after the Russian admiral and explorer who has been attributed the first confirmed sighting of mainland Antarctica, in 1820. Its waters surround, among others, two of the largest islands in the Antarctic: Alexander Island and Thurston Island. You will sail amid ice floe, blocks of sea ice and majestic icebergs. The coastal areas along the Bellingshausen Sea are home to large colonies of emperor penguins. Depending on the season, you may get the chance to observe some of these creatures in the open sea.
