Sail to Antarctica the challenging way aboard an icebreaker that crosses the Ross Sea. Dutch polar cruise company Oceanwide Expeditions ratchets up the adventure factor with two cruises from South America to the Antarctic Peninsula.
There's a 30-day cruise from South America to New Zealand and another 30-day cruise in return, from New Zealand to South America.
Participants aboard the Ortelius will visit remote locations such as Peter I Island, the huts of British explorers Ernest Shackleton and Robert Falcon Scott on Ross Island, the famed McMurdo Station in Antarctica, and an area known as the Dry Valleys, which has a Mars-like landscape.
In terms of wildlife, you can expect good sightings of birds such as emperor and adelie penguins, skuas and petrels. Orca and minke whales as well as Weddell and crabeater seals ply the waters of the Ross Sea.
