Weddell Sea Antarctica Cruises & Tours for 2026-2027

As you round the Antarctic Sound in the northeastern corner of the Antarctic Peninsula, huge tabular icebergs announce your arrival to the Weddell Sea, where Shackleton’s ship Endurance was famously trapped and crushed. Late summer cruises have the best chance of charting a safe course through the ice-clogged Weddell Sea, and if the ice flow is too thick, cruises may be diverted to clearer waters around the western side of the Antarctic Peninsula. In the Weddell Sea, you'll spot Antarctic fur seals and southern elephant seals as you hike and kayak along the icy coastline. Camping is available on some cruises and sites are decided based on prevailing ice and weather conditions. Explore the islands of Dundee, James Clark, and Ross. On Devil Island, you will see a large Adélie penguin rookery and, if you are lucky, a view of Mount Erebus.
