The Komaktorvik Lakes are a pair of elongated lakes situated in the Torngat Mountains of northern Labrador, within Torngat Mountains National Park. Together, the two lakes form roughly ten miles of connected water, separated near the eastern end by a moraine. The valley they occupy is nearly ten miles long and no more than half a mile wide at its broadest point, with mountain walls rising to approximately 4,000 feet on either side. From the outlet of the lower (smaller) lake, the ocean lies about fifteen miles distant.

The lakes are part of the Komaktorvik River watershed and are accessible by floatplane, as commercially guided float plane landings are permitted on Komaktorvik Lake under Parks Canada regulations. Landing permits are required for any aircraft or helicopter landing within the park and must be applied for in advance through the Parks Canada office in Nain. Currently, landings are limited to commercial aircraft companies and commercially guided trips for the purpose of dropping off and picking up clients. Paddlers planning a visit should contact the Nain office well ahead of their trip to arrange permits and registration.

The lakes are known for arctic char, which undertake spawning runs in the Komaktorvik River system. Arctic char are described as the most northerly of freshwater fish and represent the large boreal ancestor of the brook trout. The surrounding terrain is remote wilderness, and the valley's extreme narrowness relative to its length, combined with the towering mountain walls, gives the paddling environment a pronounced sense of enclosure and scale.

The area falls within Torngat Mountains National Park and is also adjacent to Labrador Inuit Lands administered by the Nunatsiavut Government; access to or across those lands requires the consent of the Nunatsiavut Government. Given the park's location in the high subarctic, the water is described as ice cold. The remoteness of the location means paddlers should plan for self-sufficiency, as communications can be unreliable due to the earth's magnetic field affecting radio equipment in the region.
