The spectacular aurora borealis is a natural phenomenon best viewed in the dead of winter and far away from city lights. Not surprising, as Churchill's tundra provides both requirements, its one of the best places in the world to view nature's own theatre unfold. With little pollution, clear night skies and comfortable accommodation, you won't have to stress or freeze to see the lights. Plexiglass 'aurora domes' keep you relatively warm while you wait for the show to start, but if you want to be surrounded by the dancing sky and hear the crackling of the lights overhead, contact one of the local operators to take you to their cabins by snowmobile. They often provide the necessary clothing, and layered with as much... animal as possible, you're sure to stay warm in the 40 below zero temperature while the hot cocoa will keep you satiated. The best time to view the lights are in winter from November to March. 2012-2013 is apparently the prime period to view them so get cracking and book your flight from Winnipeg, Manitoba's capital.
