After Lake Nipissing and Trout Lake, Otter Lake is the largest lake in North Bay. The Otter Lake area is a pristine, undeveloped, very large natural area with exciting geographical and natural history. It is just 15 minutes from downtown North Bay, making this area possibly the best-kept secret of the city. It is an excellent area in which to hike, canoe, orienteer and snowshoe. No buildings exist on the entire shoreline. Not regularly maintained.
