Algoma’s Crescent Beach Boardwalk doesn’t allow dogs. But other than that, it is perfect. The level, even walk edges a 1/2 mile stretch of sandy beach along Lake Michigan. It is capped on one end by a picturesque lighthouse (and why else have one?) and teeny changing room. On the other end is a small dog swim area. This is a great place to stop and stretch your legs or take a dip on your way to or from Door County.
