Most of the Arctic consists of the Arctic Ocean, 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.
- Greenland — a vast self-governing territory of Denmark
- Iceland — the northernmost (or least-extended-to-the-south) fully independent nation on Earth
- Jan Mayen — home to a tiny Norwegian radio and weather station
- Svalbard — by far the most visited islands within the Arctic Circle, a territory of Norway
- North Pole — not actually an island, just a point on a vast shifting and floating mass of ice
- ATOW1996 — northernmost bit of land on Earth
Northern Canada includes many islands as well as much mainland territory. The islands include:
Russia has an exceedingly long arctic coast with a number of islands off it.
- Novaya Zemlya
- Severnaya Zemlya
- New Siberian Islands and a group north of them that includes Bennett Island
- Wrangel Island - a national park and World Heritage Site
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. 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.

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 Northern Lights 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 cold weather. Also beware of polar bears.
