DeTour DeTour is surrounded on three sides by water, Lake Huron, the St. Mary's River and DeTour Passage. As you might have guessed our primary business is tourism in both the summer and winter. Our summer highlight is the 88 slip DNR Marina with full services, along with three local boat ramps with ample parking (including a launch ramp on Caribou Lake). We have miles of beaches, some sandy, where you rarely see another sunbather. There are several waterfront picnic areas and the "northern-most" Botanical Garden in Michigan all with views of passing Freighters. In the winter we have over 50 miles of groomed local snowmobile trails, a large parking/staging area and easy access to thousands of miles of E.U.P. and Canadian trails, via Drummond Island. So, checkout our web site but more importantly come on U.P. for a visit, just hang a right 15 miles north of the Mackinac Bridge, on M-134 and follow the signs to DeTour Village.
