Medium-sized marina with multiple docks, several small buildings along the waterfront, and a striped surface parking lot with visible vehicles adjacent to railroad tracks.
Dune Harbor is a marina located in Portage, Indiana, along the southern shore of Lake Michigan, part of the Great Lakes system, and is situated near the Indiana Dunes National Park, offering a blend of coastal dunes and freshwater lakefront scenery. It primarily serves recreational boating and sailing enthusiasts who explore the vast waters of Lake Michigan, known for its strong winds and diverse navigational challenges. This region in northwestern Indiana provides access to both sheltered bays and open lake expanses for boating activities.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
