Did you know one of the best places in the world to see polar bears is in Russia? Wrangel Island is not easy to visit: you need several permits, and it can only be reached by helicopter. But once you’re there, it’s breathtaking. Its harsh polar climate doesn’t stop the island from having an amazingly diverse eco-system. It has the densest population of polar bear dens in the world, and is also home to walruses, snow geese, muskoxen, arctic foxes, and reindeer.
