The main access to Quttinirpaaq National Park is from the Tanquary Fiord Airport. This is the second farthest north national park in the world. (Only the one at the north end of Greenland is further.) For the most part, it is a polar desert with very little annual precipitation. It's also the second largest national park in Canada.
