Grand Rapids is a moderate city with enough of a downtown to be considered large and enough pleasantries to keep that small town charm. Tourists certainly don't flock here, which is a bonus for any quick stop or through trip.
Heritage Hills is an underappreciated stretch, lined with historic mansions that vary stylistically and historically. The Frank Lloyd Wright designed Meyer May House is pristinely restored and available for walkthroughs. The Voigt House Victorian Museum offers décor that predates the Meyer, ripe with elegance and distinction.
Grand Rapids also has the Fredrick Meijer Gardens and Sculpture Park, which is a vast and beautiful link to the natural world.
Nearby Grand Haven and the Lake Michigan Waterfront offer various activities and sightseeing opportunities. You can rent a charter or map out your own trip along the far-reaching coastline.
