The aim on this voyage is to head as far south as ice and weather permit. After a few days exploring the 'deep south', there are further shore excursions on the northerly route along the Antarctic Peninsula. The ship is small enough to navigate through the narrow Lemaire Channel, with glacial walls towering high on both sides, leading to a jigsaw of jewel-like islands that are home to huge penguin rookeries, Elephant seals and countless seabirds. There are also whales: imagine a pair of Humpbacks, at least 30 tonnes of mammal, rising imperiously against a turquoise ice-wall viewed from a Zodiac only metres away, and you have the essence of the Antarctic.
