Frederik Meijer Gardens and Sculpture Park
“One of the nation’s most significant sculpture and botanic experiences, Meijer Gardens [Grand Rapids] includes Michigan’s largest tropical conservatory; five indoor theme gardens; outdoor gardens, nature trails and boardwalk; sculpture galleries and permanent sculpture collection; library; café; gift shop; education center; and meeting rooms. Both indoors and outdoors, the 158-acre main campus is barrier free and handicap accessible.” Thank you to Larisa Draves for letting me know about this.

All the paths through the gardens are wide and accessible. These include the Leslie E. Tassell English Perennial & Bulb Garden, the Gwen Frostic Woodland Shade Garden with its Kettle Pond, and the Richard and Helen DeVos Japanese Garden.
