Nachvak Fiord is a deep, remote Arctic fjord in northern Labrador, nearly 2 kilometers wide and 20 kilometers long. It is surrounded by the Torngat Mountains, which include some of the highest peaks in Labrador, such as Mount Razorback to the north and Mount Caubvick to the south. The fjord's western end divides into two arms: Tallek Arm and Tasiuyak Arm. The overall character is one of extreme wilderness, featuring steep cliffs, glacial valleys, and an untouched landscape. This remoteness defines the paddling experience, which is suitable only for highly experienced, self-sufficient expedition kayakers prepared for significant logistical challenges and potential hazards. A specific hazard noted for paddlers is the presence of polar bears, with one expedition report stating they observed more polar bears in Nachvak Fiord than elsewhere during a traverse of the Torngat Mountains, describing the fiord as "particularly dangerous." The area has historical significance as a former summer fishing station for Inuit and was the site of the most northerly Hudson's Bay Company post in Labrador from 1868 to 1905. Several small rivers and canoeing routes empty into the fjord, including the Palmer River, which flows into Tallek Arm.
