The Marquette Underwater Preserve offers outstanding scuba diving along Lake Superior’s shoreline in two areas of Marquette County, the Marquette Unit and the Huron Islands Unit. The Marquette Unit borders 24 miles of Upper Peninsula coastline extending out into Lake Superior to a depth of 200 feet. The Huron Islands Unit embraces the clear waters surrounding the Huron Islands west of the Marquette Unit– a group of granite upcroppings rising from the bottom of Lake Superior.
Boaters can reach the Huron Islands from the Big Bay Harbor of Refuge at Big Bay or from Wirtz's Marina at Skanee in Baraga County. In either case, it is a cruise of over 12 miles to the Islands, so boaters must take appropriate precautions.
