Each year, hundreds of Sami herd their reindeer flocks across Scandinavia's northernmost parts, a journey which takes two months, covering hundreds of miles.
Around 3,500 reindeer and dozens of Sami make the annual trip across the snow, dashing from Karasjok, the Sami capital of Norway, over the snowy plains of northern Scandinavia, and across the Finnish border.
The Sami are the indigenous people of Scandinavia and live in the Arctic parts of Norway, Sweden, Finland and Russia, in an area recognised as Sapmi.

Long way to go: Around 3,500 reindeer made the annual trip across the snow, which took nearly two months in total
Although traditionally associated with reindeer herding, only ten per cent of the Sami remain in the reindeer business, with some 2,800 living as full-time semi-nomadic herders.
