There are 15,000 golf courses in the United States. Yet, only one involves a mile-and-a-half, horse-drawn carriage ride between nines. And only one is laid out on a battlefield where American soldiers died in a failed attempt to wrest control of the Great Lakes from the British. Both of them are on Mackinac Island, which boasts two iconic golf courses that each are literally one of a kind. Plus, Mackinac Island is home to an incredible, natural grass putting course that’s perfect for date nights and family fun.
