The Ontonagon Marina is a beautiful area located just off of the south side of Lake Superior and on the Historic Ontonagon River. Our Marina serves as a Safe Harbor to enable boaters to take shelter in an emergency and we are devoted to our customers by having friendly, honest and knowledgeable staff. We have thirty one (31) seasonal slips, six (6) transient spots, picnic areas, showers, restrooms, a fish cleaning station, fuel services, and pump out services. The area provides transportation to town for shopping, meals and tourist attractions located close by. Our goal is to make the Ontonagon Marina a reoccurring visit in your vacation plans!
