Bruce National Park, located on the Bruce Peninsula, which almost cuts off Georgian Bay from Lake Huron, is a patchwork of limestone cliffs, beach and ancient forest scenery. At Tobermory, the cliffs run underwater, surfacing as the Fathom Five Islands, such as Flowerpot and Bears Rump, a separate national marine park. The dramatically varied landscape and rich natural and human history are part of the West St Lawrence Lowlands Natural Region preserved by the park. The Lake Huron shore is alternately rimmed by rock, sand and fen wetlands which, coupled with the mild climate, provide a greatly diversified habitat for animals and plants. The boundaries of its 155 square kilometres encompass the former Cyprus Lake Provincial Park and lands purchased from private owners as they become available.
