St. Margarets Bay is a coastal bay on the Atlantic coast of Nova Scotia, Canada. The bay's shoreline offers several access points for paddlers. A formal boat launch site is located on Highway 3, approximately three kilometers west of Queensland Beach Provincial Park. Another known entry point is beside Todd Island Road. Bay Lookout Park, located at 7124 St. Margarets Bay Road in Boutiliers Point, is a day-use park with a boat launch administered by the Halifax Regional Municipality and is free to use. The bay is a popular area for recreational boating, including sailing adventures and commercial kayak tours, indicating the presence of other boat traffic that paddlers should be aware of. The bay's character includes a mix of developed shoreline and natural vistas, with one paddling route noted for passing an iconic castle cottage viewpoint and returning along a golden shoreline. The St. Margarets Bay Trail, a 32km stretch of the Rum Runners Trail, runs along the coast, providing potential overland access points and scenic views. For paddlers using their own craft, early morning and evening are great times to be on the water. The bay is a saltwater feature subject to Atlantic Ocean conditions, including tides, winds, and potential swell, which are critical factors for trip planning that paddlers must independently research prior to departure.
