Indiana’s Lake Michigan shoreline stretches just 45 miles — the shortest Great Lakes coastline of any state — but those 45 miles from the Illinois border at Hammond and Gary through Michigan City to the Michigan border at New Buffalo contain some of the most spectacular freshwater dune and shoreline scenery in North America and serve as the primary Lake Michigan boating gateway for the greater Chicago metropolitan area’s southern suburbs. The Indiana Dunes National Park — established as a national park in 2019 after decades as a national lakeshore — protects 15,000 acres of Lake Michigan shoreline, sand dunes, wetlands, and oak savanna along the Indiana shoreline and represents one of the most ecologically diverse national park units in the country despite its modest 45-mile corridor. The dunes themselves — rising up to 192 feet above the lake at Mount Baldy — create the most dramatic visual backdrop of any boating environment in the Indiana directory, and the Indiana Dunes State Park beach within the broader national park area draws millions of visitors annually who access the lake from the same shoreline that recreational boaters launch from at Washington Park Marina in Michigan City. The Indiana shoreline’s proximity to Chicago — Michigan City sits just 60 miles east of the Chicago Loop — makes this the most Chicago-influenced boating corridor in the directory outside of Illinois itself, with significant weekend boat traffic from the metropolitan area that defines the lake’s summer character and service market intensity.

The fishing along Indiana’s Lake Michigan shoreline and the immediately adjacent waters reflects the Great Lakes character of federal water with all the species that the Lake Michigan ecosystem supports. Chinook and coho salmon are the primary summer trolling target — charter operations out of Michigan City’s Washington Park Marina target salmon in the open lake from June through September with consistent results that draw serious trophy anglers from across Indiana and the Chicago suburbs. Lake trout provide year-round deep water jigging opportunities in the 60 to 120-foot water column off the Indiana shoreline. Brown trout and steelhead are available in the nearshore zone during spring and fall migration runs that draw dedicated shore casters and small boat anglers to the Indiana shoreline’s public access points. Yellow perch along the breakwaters and piers produce consistent catches for casual anglers who don’t want to venture into open lake conditions. The St. Joseph River at its Lake Michigan mouth on the Michigan border — just minutes from Indiana’s eastern shoreline limit — adds a productive river fishery for steelhead and salmon during fall and spring runs that Indiana anglers access as easily as Michigan residents.

The Indiana Dunes National Park shoreline has specific no-wake zones, swimming beach restricted areas, and seasonal wildlife protection closures — check current NPS regulations at nps.gov/indu before launching near the national park shoreline.

Book motor service in Michigan City or La Porte before the Memorial Day weekend — the Chicago suburban boating community launches simultaneously with Indiana residents and the 60-mile proximity to Chicago creates the most intense spring service demand of any Indiana hub.
