Eclipse Channel is a coastal channel located within the remote Torngat Mountains National Park in Labrador, Newfoundland and Labrador. It connects a river gorge and waterfall system to the open Labrador Sea. The channel is situated in a dramatic, treeless landscape of mountainous tundra, characterized by high peaks and deep valleys. The aesthetic is one of raw, expansive wilderness, where the water meets steep, rocky terrain. The area is filled with vibrant tundra and is known for sightings of seals in the water.

This is an extremely remote and exposed coastal paddling environment. The channel is subject to significant tidal influence. Historical tide data for the station at Eclipse Channel indicates a semi-diurnal pattern with a typical range of approximately 1.0 to 1.8 meters, though predictions should be verified annually from official Canadian Hydrographic Service publications. Paddlers must plan routes around these tides, as currents can be strong where the channel meets the sea and where it receives outflow from a river gorge. This river empties into the channel via a long, abrasive gorge and a 20-meter waterfall, creating turbulent and dangerous conditions at its terminus; this area should be considered a major hazard and avoided. The open exposure to the Labrador Sea means the channel is susceptible to wind, waves, and weather systems moving in from the ocean, which can change rapidly. Polar bears are present in this region and are a serious safety threat; travel requires vigilance, local knowledge, and appropriate safety measures.

Access is exclusively by boat or expedition cruise ship, as there are no roads or established facilities for paddlers. There are no designated launches, take-outs, or amenities. Visitation is typically part of guided expedition tours, often involving zodiac landings from larger vessels. The best and only practical season for paddling is during the brief summer, coinciding with the ice-free period. The water is cold year-round. Paddling here is a true expedition undertaking, suitable only for experienced, self-sufficient groups prepared for wilderness survival, variable marine conditions, and wildlife encounters in one of Canada's most isolated national parks.
