Russia's vast nature has always fascinated people.
Four spectacular regions are representative of 'Russia's hidden paradises': The exclave of the Curonian Spit forms the westernmost tip of Russia with the oldest ornithological research station in the world. In the far east on Kamchatka, Lake Kuril offers a paradise for the world's largest brown bears. High in the north on Yamal live the reindeer herds of the Nenets. Climate change and gas production are rapidly changing their icy world. In the south the mighty Caucasus borders the country. The ancient mountain forests of North Ossetia are ideal habitats for Europe's largest primeval cattle.
