Michigan is the Great Lakes State, uniquely surrounded by four of the five Great Lakes and offering 3,288 miles of freshwater shoreline — more than any other state except Alaska. From the dunes of Sleeping Bear National Lakeshore to the vibrant arts scene of Detroit, Michigan combines stunning natural landscapes with world-class cities, a rich automotive heritage, and a thriving food and craft beer culture.

Michigan has a temperate continental climate with four distinct seasons. The Great Lakes have a moderating effect on temperatures but also increase snowfall in the 'snow belt' areas downwind of the lakes (particularly western Lower Michigan and the UP). Summers are warm with occasional heatwaves; winters range from cold-but-manageable in the south to severe in the Upper Peninsula. Lake Michigan beaches are best July-August. Fall foliage is spectacular in September-October.
