21500 S Pipe Is, Detour, MI, 49725
About This Home
Tucked away in the St. Marys River within the pristine waters of northern Lake Huron, South Pipe Island is a once-in-a-lifetime opportunity to own a piece of Great Lakes history. Spanning 13.56 acres, this beautifully maintained private island in De Tour Village is rich in maritime heritage and protected natural beauty. A true recreational paradise with opportunities for boating, fishing, hiking, camping, and more. At its heart stands a fully operational lighthouse, built in 1887 and now maintained by the Coast Guard, alongside the original light keeper’s house and historic boathouse- all meticulously maintained to honor their legacy. The property also includes three rustic sleeping cabins, a workshop, and even a private island theater, blending historic preservation with quiet, off-grid hospitality. A private harbor ensures convenient water access and shelter from the open lake- perfect for summer arrivals by boat. The island is protected by a conservation easement, which ensures the preservation of its natural character and prevents future development, safeguarding the landscape and history for generations to come. South Pipe Island is more than a property- it’s a living piece of Michigan’s maritime past and a peaceful sanctuary for those seeking solitude, history, and the wild beauty of the Great Lakes.
