TOBERMORY, ONTARIO is located at the tip of the Bruce Peninsula, a narrow finger of land separating Lake Huron from the Georgian Bay. The Georgian Bay, in many people's opinion, should have been designated the sixth Great Lake, but Samuel de Champlain, the first European to explore and map the area in 1615, saw it as a bay of Lake Huron and called it La Mer doucethe calm sea. Boaters have been working and playing on that calm sea ever since.Tobermory is one of the premier towns on the Georgian Bay and has the good fortune of being home to two national parksone above the water and one below. It is also set in the heart of a World Biosphere Reserve. Tobermory is uniquely suited to be a northern boater's paradise.
