Pictured Rocks National Lakeshore
Located along the northern coast of Michigan's upper peninsula (the "U.P."), Pictured Rocks is best seen from the water, which allows you full views of the spectacular cliff formations, stained with colors caused by mineral seepage from the rocks. A 2-1/2 hour boat tour leaves from Munising and gives great close-up views of the park.
You can also see limited views by driving into one or two access points within the park; or hike the park's trail system (the park contains more than 42 miles' worth of trails). The park is popular with hikers and campers - the lakefront campsites are incredible.
