About Lake Michigan
Lake Michigan is one of North America’s five Great Lakes and the only one entirely within the United States. It covers about 58,000 square kilometers and is a major freshwater resource and transport corridor.
Beaches, dunes and urban waterfronts line a shoreline that runs thousands of kilometers; popular recreational areas include the Indiana Dunes, the Door Peninsula and the lakefront parks of Chicago. The lake reaches a maximum depth of about 281 meters and supports commercial shipping, sport fishing and ferries.
The lake basin was carved by glacial ice during the last Ice Age and has been central to indigenous settlement and later European colonization, trade and industrial development on its shores. Port cities grew in the 19th and 20th centuries as rail and shipping networks expanded.
Lake Michigan is bordered by the U.S. states of Michigan, Indiana, Illinois and Wisconsin and lies west of Lake Huron, linked to it by the Straits of Mackinac.
- Connection to Lake Huron: The Straits of Mackinac connect to Lake Huron and keep the two lakes at essentially the same water level, allowing shipping between them without locks.
- Shoreline cities: Major cities on its shores include Chicago, Milwaukee and Green Bay, all of which have extensive lakefronts and ports.

How to Get to Lake Michigan
Lake Michigan has many public access points along Michigan’s west coast. On the Michigan side, drive via US‑31 (the principal lakeshore route) or I‑94 to lakeshore towns such as Muskegon, Holland, Grand Haven and St. Joseph; most public beaches and parks have nearby parking and are a short walk from town centres or designated lots.
Tips for Visiting Lake Michigan
- To avoid the busiest beach crowds, visit Lake Michigan shoreline parks and towns on weekday mornings or in shoulder seasons (late spring or early fall); popular spots draw heavy weekend and holiday traffic in summer.
- If you plan boat or lighthouse trips, use smaller harbors and local tour operators rather than the biggest marinas-smaller departures often mean fewer passengers and access to less-visited points along the shore.
- For sailing, expect winds to pick up in the afternoon; mornings are generally calmer for light-wind cruising or lake crossings, so book early departures when possible.
