Which Should You Visit?
Both islands ban cars and require ferry passage, but their personalities diverge sharply. Block Island sits 13 miles off Rhode Island's coast, delivering weathered New England authenticity with dramatic bluffs, pristine beaches, and a landscape shaped by Atlantic storms. Its 17 square miles feel genuinely remote, with bike paths threading between stone walls and wind-swept moors. Mackinac Island, positioned between Michigan's peninsulas, operates more like an elaborate Victorian theme park. Horse-drawn carriages clip-clop down streets lined with fudge shops, while the Grand Hotel's 660-foot porch overlooks manicured gardens. Block Island attracts those seeking solitude and natural beauty, while Mackinac Island caters to families wanting structured entertainment and nostalgic Americana. The choice hinges on whether you prefer raw coastal isolation or orchestrated 19th-century fantasy.
