The swift flowing St. Clair River empties into Lake Saint Clair through the largest freshwater river delta in the world. It is a vast marshy landscape unlike any in Michigan.
The best views of this unique landscape are to be found on Harsens Island, a horseshoe of high ground surrounding a marshy interior. A short ferry ride across the North Channel of the St. Clair River drops you at about the middle of the crescent. A road hugs the coast in both directions.
