DeTour Reef Light is a non-profit-operated lighthouse marking the southern entrance of the DeTour Passage between the eastern end of Michigan's Upper Peninsula and Drummond Island. The light is an automated active aid to navigation. It marks the northern end of Lake Huron. The passage is used by almost all of the Great Lakes commercial freighter traffic moving to and from Lake Superior, with approximately 5,000 vessel movements annually. It is said to be "the gateway to Lake Superior." In addition, many recreational boaters use the passage. The Light is located in Lake Huron, three miles south of DeTour Village.
This cache is located off one of the many trails located in Sleepy Hollow State Park. Most of the trails are hard packed making a bike a great way to get to the caches in the area. Please note there are some roots on the trails. Keep in mind during hunting season to be aware of hunters in the area. Hunting is allowed from September 15 until April 1st each year.
