The Sami are some of Europe's last indigenous peoples, reindeer herders who for thousands of years have lived a nomadic lifestyle in the Arctic wilderness. In their homeland, spread across northern Norway, Sweden, Finland, and Russia, the notion of time is untethered from the cycles of the sun and is tied instead to something far more important: the movement of the reindeer. Experience spectacular aurora displays and visualizations of local folktales about the aurora as you accompany the Sami on their annual "reindeer walk" 200 miles north of the Arctic Circle.
