DeTour Passage Underwater Preserve

The DeTour Passage is located at the easternmost tip of Michigan’s Upper Peninsula is a natural point channeling ships bound from Lake Huron to the locks at Sault Ste. Marie into a narrow strait between the eastern tip of Michigan's Upper Peninsula and Drummond Island.

Shore accessible dive sites are frequent along the coast of the Upper Peninsula and Drummond Island. These include the hulls of abandoned wooden ships. Visitors should be aware of private property rights when accessing shore locations. Permission of property owners should be obtained when appropriate before crossing or accessing private property.

The remains of lost ships rest there in fairly shallow waters easily accessible to divers. Divers should be prepared to locate the various shipwrecks themselves for diving. Boat captains and divers should take care to avoid anchoring into the wrecks and doing unnecessary damage.
