If a gruelling 42-hour, 126-kilometre open water swim doesn't appeal, Aurora Expeditions wide-range of expedition cruises offer passengers the chance to have the ultimate adventure through a number of different activities ranging from an easy 20-second 'Polar Plunge' to a 50-kilometre trek across an a subantarctic island.
Antarctica comes in at number one as an adventurer's playground and passengers can choose from an array of optional activities. Camp on the ice like an Antarctic explorer, paddle a sea kayak though waters teeming with wildlife, or any good swimmer can don a dry suit and plunge into the icy cold waters to snorkel with penguins.
If those options don't cut it, experienced adventurers can test their skills at climbing one of the Antarctic Peninsula's thousand-feet peaks, scuba dive below Antarctic waters where ice walls sparkle and marine life flourishes, or follow in the footsteps of one of the world's most famed Antarctic explorer - Sir Ernest Shackleton - on a three-day, 50-kilometre crossing of South Georgia's interior.
In the Northern Hemisphere, visit Greenland, the birthplace of kayaking, and paddle amidst spectacular mountain scenery and towering icebergs the size of high-rises. In Alaska, beginners can learn to stand up paddle board, or enjoy some easy-paced kayaking and polar snorkelling.
Closer to home, passengers who enjoy the bush can sign up for a 10-kilometre, rock hopping trek through Western Australia's Kimberley wilderness to visit the old Kunmunya Ruins, an old Presbyterian Aboriginal mission from the early 1900s as well as the base camp of expedition leader Mike Cusack and his wife Susan's during their year in the Kimberley as Australian Geographic's first Wilderness Couple in 1987. The exclusive opportunity to join Mike on his yearly pilgrimage back to the site is only available on Aurora Expeditions Kimberley Coast voyages.
