Islands of the Arctic Ocean
The Arctic mainly consists of the Arctic Ocean, which is littered with islands, mostly fragments of the North American, European, and Asian continental masses. Some are inhabited; others are completely covered in snow and ice and therefore uninhabitable. Several of the most interesting lie in the border waters between the Arctic and northern Atlantic Oceans, 60° and northward toward the Pole.
The largest number of Arctic islands are parts of the Nunavut and Northwest Territories of Canada, and several are part of northern Russia; most of these are barren and uninhabited, and are covered (to the extent that there's anything to say about them) in their respective countries' articles.
Greenland – so large it hardly deserves to be called a mere "island" – lies largely in the Arctic Circle. Although it is arguably part of continental North America, it bears cultural and practical similarities to its smaller neighbors in the Arctic region. Likewise, Iceland barely kisses the Arctic Circle and has a fairly mild climate, but still has a sparsely-vegetated landscape and moderate accessibility issues. The Faroe Islands are closer to mainland Europe than any of the others (not much further out to sea than the Shetland Islands), but their small size leaves them somewhat more isolated. Jan Mayen and Svalbard are quintessentially Arctic – remote and harsh – but habitable.
Although they lie on or near the "great circle" routes taken by airliners between Europe and North America, the Arctic islands are generally treated as "fly-over" territories, with fewer stops since passenger planes gained the ability to cover the distance without refueling. Because of their historical ties to Europe, they are easier to get to from there than from Canada or the U.S.

Arctic scenery varies throughout the seasons. Travelers have opportunity to see an abundance of wildlife throughout the course of a cruise or land trip. Best times to go vary based on which wildlife viewing is preferred. From late May through early September one can see caribou, moose, humpback whale, beluga whales, seals, grizzlies, polar bears, Arctic foxes, muskoxen, and up to 200 species of birds.
The aurora borealis may be visible at the highlight of the dusk and nighttime hours on a cruise.
This is polar land and you need many layers of clothes to survive; see travelling in cold weather. Also beware of polar bears.
