Georgian Bay is a freshwater bay off of Lake Huron in the province of Ontario. It is around 190 kilometres (120 miles) in length and 80 kilometres (50 miles) in width, covering approximately 15,000 square kilometres (5,800 sq miles), which makes it nearly 80% the size of Lake Ontario. The region is known for its rugged beauty, with Eastern Georgian Bay comprising part of the southern edge of the Canadian Shield. Granite rock formations and windswept eastern white pines characterize the islands and much of the bay’s shoreline. This sailing location is great for all levels of sailing experience, with generally peaceful weather and picturesque towns like Midland and Penetanguishene.
