Vast swaths of beautiful, unfenced wilderness give adventurers unique freedom to wander at will, whether on foot, by ski or by dogsled. With virtually no roads, transportation is expensive, but splurging on helicopter and boat rides is worth every penny. These whisk you over truly magnificent mountainscapes and glaciers or through some of the planet's most spectacular fjords. Greenland also offers world-beating but charmingly uncommercialised opportunities for sea kayaking, rock climbing and salmon fishing.
