Torch Lake at 19 miles (31 km) long is Michigan's longest inland lake and at approximately 18,770 acres (76 km²) is Michigan's second largest inland lake. Surrounding it are several townships including Torch Lake Township, Central Lake Township, Forest Home Township, Helena Township, and Milton Township in Antrim County and Clearwater Township in Kalkaska County, Michigan. Several villages and hamlets lie along its shore, including Alden, Eastport, Clam River, and Torch Lake.
The lake is known for nature activities including hiking, canoeing, fishing and diving. Owing to the low amount of boat activity, it is a nature-lovers paradise. Noted for its exceptional beauty; its waters are unusually clear and exhibit a bright turquoise hue, often resembling Caribbean waters. This quality has made the lake a popular spot for the development of resorts and second homes with notables including Kid Rock, Eminem, and Michael Moore owning vacation homes on the lake.
