Lake Rosseau, Muskoka Lakes

Windermere House



Perhaps one of the most popular recreations lakes, Lake Rosseau is one of the “Big Three” (Lake Muskoka, Joseph, Rosseau) jewels of Muskoka that grace the southern end of the Canadian Shield. Approximately 15 miles long and 2 1⁄2 miles wide in most places, its numerous islands, bays, and points make it great location for water sports. 

Lake Rosseau is located just north of Lake Muskoka and northwest of Bracebridge. The village of Rosseau is on the north eastern shore. Rosseau is connected to Muskoka by a lock system at Port Carling and to Lake Joseph through the narrows and Port Sandfield and the Joseph River.
