Douglas Beach is a small public beach just outside of Saugatuck, MI, just over an hour's drive from Kalamazoo. Access is down a steep flight of stairs. The park is in a residential neighborhood perched on the dunes above Lake Michigan and the upper part has parking for about a dozen cars, restrooms, and a couple of picnic tables. The lower part is a nice sandy beach.
While the public beach is relatively small, the Michigan Supreme Court affirmed the public's right to walk along privately-owned beachfront, so it's possible to walk for miles along the water.
It's easy to find the beach by following the signs for the Rosemont Inn.
