 In the heart of the Ontario lake country are the two areas known simply as "Muskoka" and "Haliburton" (which are both actually a district or county respectively).To most people in Ontario, the area is simply part of what is known as cottage country, in reference to the some 250,000 summer cottages on the lakes of southern Ontario.North Bay has massive pink granite, partially tree-covered cliffs, rising hundreds of feet out of the lake along the shoreline.
