This is what we came here for. It can't be guaranteed, obviously, but the northern lights are one of the main reasons people go to Lapland in the winter. We were lucky to see them several nights, the strongest of which happened the first night of our snowmobiling trip. We were cruising along a frozen lake, one hour after sunset. Suddenly, a faint green wave started moving towards us. We stopped the snowmobiles, killed the engines and grabbed our camera equipment. For the next two hours, we shot the aurora as it glistened across the sky. Eventually, it meandered off in the distance and disappeared. It was a magical experience, akin to the sunrise at Machu Picchu or a whale breaching next to your kayak. I like to believe that even the most hardened and cynical of travelers would be brought to their knees by the sight. Pure bliss.
