The Unesco-protected Lapland Biosphere Reserve consists of 2784 sq km (1074 sq mi) of almost pristine wilderness and is the most accessible nature reserve in Arctic Russia. Visitors can trek through the wilderness - the best times are from March to September - or traverse it on skis, snowshoes or skidoos.

Over 1000 reindeer live on the biosphere's territory, one of the largest concentrations in Europe. Along with 33 species of mammals (including brown bears, elks and wolves), 201 bird species and 15 species of fish, there are more than 900 species of higher plants, mosses and lichens.
