Northeast Greenland National Park
Northeast Greenland National Park is the world’s largest, a 375,000-square-mile (972,000-km2) U.N. Biosphere Reserve covering the northeastern quarter of this North Atlantic island wilderness. Beyond its towering cliffs meeting the sea in walls of glacial ice and ancient rock—some of the oldest on earth—live musk oxen, polar bears, caribou, arctic wolves, foxes, hares, and delicate flora. Whales, seals, and walruses shelter in fjords. Long closed to all but scientific teams, it’s now open to private groups, though with limited facilities and difficult access. The short visitor season is early July–September. Permit applications must be in by December of the year prior to a visit.
