Gathered around a Norwegian campfire, 350km into the Arctic Circle, huddled from head to toe in exploration overalls and snow boots we had one of those life-affirming moments. Experiencing the Northern Lights in Tromso is one of those occasions when you really feel alive.
We only had to stare into the clear pinpricks of the Milky Way, spread across the night sky in a haze of primordial luminescence, whilst our tour mates clanked about with torches and cameras attempting to capture the faint Aurora Borealis in rolling hazy streams over our heads. You know, those moments.
