See the northern lights
Nigel Tisdall: "The northern lights are one of nature’s great displays: a mysterious, multicoloured show in which the night sky is suddenly lit up with a wondrous glow that twists and swirls like a heavenly lava lamp.
"Elusive and ethereal, it is one of the great, timeless thrills of travel, a beautiful, shifting dance of nocturnal rainbows that many viewers find a humbling and spiritually uplifting experience.
