It’s always been an axiom of adventure travel that heli-skiing in Antarctica is the preserve of those who can afford to charter yachts and the helicopters to go with them. Enter Geordie Mackay-Lewis, co-founder of adventure outfitters Pelorus (pelorusx.com; £15,200 per person), who’s making the rare adventure more accessible. Guests fly to King George Island, board an upgraded ice-class vessel kitted out with two helicopters and make for Livingston Island and the rest of the Antarctic Peninsula, skiing in groups of four with guides. If the weather doesn’t play nice, there are Zodiacs in which skiers can put to shore, skin up and ski down. Or they can visit penguin colonies, whale-watch – or just sit back and admire one of the last great polar wildernesses on earth.
