Greenland with its capital Nuuk is located in North America (Northern North America, island between the Arctic Ocean and the North Atlantic Ocean). It covers some 2,166,087 square kilometres (slightly more than three times the size of Texas) with 56,375 citizens. Kalaallisut, Danish and English are the languages used by people in Greenland (consider regional differences).
Greenland is the world's largest non-continental island, in the far northeast of North America, largely within the Arctic Circle. If you stay on the typical tourist paths you do not need any permissions, but any expeditions (including any trips to the national park, which by definition are expeditions) need a special permit from the Danish polar centre.
