Have you ever wondered how does it feel to be in -40C ? Not so much fun, but if the surrounding is under heavy snow cover turning everything into real winter paradise in Santa's Land, then the experience is absolutely worth it. Frozen land of Arctic Lapland offers some great setting for capturing Northern Lights - Aurora Borealis under snowy landscape, which is often difficult to find along the coast.
Average temperatures around - 25C, with occasional -40C, dont make it particularly friendly experience, but the one which will always be treasured. I have purposely traveled there during full moon time, as I prefer the dark blue sky that moon light creates and when there was no aurora.. there was always moon to play with.
