The only region of Russia, which is entirely located on islands. There are 87 of them in total, including the largest - Sakhalin. And every island is very different.
On one island, lazy seals love to wallow, on another, rare birds have arranged a real market, on a third - active volcanoes and abandoned lighthouses.
Residents of the Russian mainland can get to Sakhalin only by air or by sea, but it’s definitely worth it!
