Cow Head Harbour is a coastal harbour on the Gulf of St. Lawrence, adjacent to the Cow Head Peninsula within Gros Morne National Park. The harbour is connected to the larger Shallow Bay. The paddling experience here is characterized by open ocean conditions, suitable only for paddlers with significant sea kayaking experience. The area is known for high rolling swells that can become large, though they are often manageable rollers. The primary hazard is submerged rocks near shore that are difficult to see until a paddler is directly upon them. The prevailing wind is from the southwest, which can generate stronger driving waves, particularly when turning into Cow Cove (also known locally as Back Cove) on the peninsula's eastern side. Winds can arise quickly, making it essential to constantly identify potential landing sites along the route.

A common access point for paddlers approaching from the south is the boat launch in St. Paul's, located just past the steel bridge at the north end of town on Route 430. A popular route is a 10 km out-and-back trip from St. Paul's to Cow Head, taking approximately three hours. Upon reaching Cow Cove, paddlers can take out anywhere along the shore where a small back road runs close to the water, next to several small fishing sheds. From Cow Cove, a short 20-30 meter portage across the causeway allows access into Cow Head Harbour and Shallow Bay for further exploration. The back of the Cow Head Peninsula offers unique geology to observe. For the return trip to St. Paul's, paddlers should anticipate a headwind and plan for a diagonal crossing from the tip of Cow Head Peninsula to the coast near St. Paul's Point for safety. The best seasons for paddling are summer and fall. There are no specific paddling restrictions mentioned, but consulting with local knowledge about dangerous spots around the bay is highly recommended before heading out.
