Halibut Rock, just off the rocky shore of Peggy's Cove Point, Nova Scotia, is a navigation hazard, laying slightly below the surface. Extreme low tides sometimes offer a quick glimpse of its flat surface protruding above the tough of a swell. Most times cresting waves reveal its location, just southwest of the lighthouse. Halibut Rock is charted on the Nautical Chart of St. Margaret's Bay D7-4386.[1]
